Apple on Thursday released an updated version of its iTunes software following a series of announcements made during the company’s press conference in New York City. The Cupertino, California-based firm unveiled its new interactive iPad textbook product alongside iBooks 2 Thursday morning, and it also took the wraps off of an updated iTunes U service that includes new tools for teachers and a new iPad app. To accommodate Apple’s new features, the company also pushed out iTunes 10.5.3, which is available for download immediately. Apple’s official change log follows below.

What’s new in iTunes 10.5.3

iTunes 10.5.3 allows you to sync interactive iBooks textbooks to your iPad. These Multi-Touch textbooks are available for purchase from the iTunes Store on your Mac or from the iBookstore included with iBooks 2 on your iPad.

iBooks textbooks are created with iBooks Author — now available as a free download on the Mac App Store

Apple has just seeded iOS 5.1 beta 2 to developers, and hopefully, battery life is fixed for good. We’re combing through the update and will let you know what we find (it looks like you can now delete photos from Photo Stream from your iOS device), but for now, we have the full change log after the break!

Thanks, Austin!

Developing…

Notes and Known Issues

With iOS 5 being released on October 12th to everyone (well, everyone who has relatively recent Apple device), Apple is making it available to developers today for testing. It just hit Apple’s developer site, and we’re in the process of getting it installed on our devices. We’ll update you with any new changes we find, and you do the same, alright? In the mean time, the full change log we received is after the break!

Thanks, Jean!

Notes and Known Issues

The following issues relate to using the 5 SDK to develop code.

Apple’s iOS 5 will be released on October 12th for the iPhone 4, iPhone 3GS, iPad, iPad 2 and the last two iPod touch generations. We’re expecting the Gold Master to be released for developers later today. Apple’s free iOS 5 software update brings over 200 new features to the platform including some big ones like redone notifications, iMessage, built-in Twitter integration, Newsstand and more.

Apple has just seeded iOS 5 beta 7 to developers for iPhone, iPad and iPod touch testing. Apple is expected to release iOS 5 for consumers in the coming weeks. The full change log is after the break.

Accounts

• When creating an iCloud account, you can use any Apple ID as long as it is a full email address and not a MobileMe account. If you have a MobileMe account, you can move that account to iCloud. You can find more information on iCloud at: http://developer.apple.com/icloud

AirPlay

• Starting in iOS 5, video content in applications and websites are AirPlay-enabled by default.
• iOS 5 supports AirPlay of video via AV Foundation.

API Validation

• NEW: Starting in iOS 5.0 development tools beta 7, it is possible to extract APIs used by an application and have them checked for private APIs usage. This option will be offered at Validation time.

Apple TV

• Apple TV Software beta enables users to mirror the contents of an iPad 2 to an Apple TV (2nd generation) using AirPlay. This beta software also enables Photo Stream on Apple TV so users can access photos stored in iCloud. Apple TV Software beta is being provided to test the latest AirPlay functionality with your iOS 5 apps and web sites. If you wish to install Apple TV Software beta on your device, you must first register your device UDID in the iOS Developer Program Portal.
• Slideshow settings are not remembered for slideshow playback (always plays back in Reflections theme). Screen savers settings are behaving properly.

Binary Compatibility

• On applications linked against the iOS 5.0 SDK, scroll view content offsets will no longer be rounded to integral pixels during a pinch gesture.

Calendar

• Birthday calendars are not currently available via the icloud.com website or in Windows. They will be available in a future release.

Core Image

• Several filters have been added since beta 1. The current list now includes the following filters:CIAdditionCompositing, CIAffineTransform, CICheckerboardGenerator, CIColorBlendMode, CIColorBurnBlendMode, CIColorControls, CIColorCube, CIColorDodgeBlendMode,CIColorInvert, CIColorMatrix, CIColorMonochrome, CIConstantColorGenerator, CICrop, CIDarkenBlendMode, CIDifferenceBlendMode, CIExclusionBlendMode, CIExposureAdjust,CIFalseColor, CIGammaAdjust, CIGaussianGradient, CIHardLightBlendMode, CIHighlightShadowAdjust, CIHueAdjust, CIHueBlendMode, CILightenBlendMode, CILinearGradient,CILuminosityBlendMode, CIMaximumCompositing, CIMinimumCompositing, CIMultiplyBlendMode, CIMultiplyCompositing, CIOverlayBlendMode, CIRadialGradient,CISaturationBlendMode, CIScreenBlendMode, CISepiaTone, CISoftLightBlendMode, CISourceAtopCompositing, CISourceInCompositing, CISourceOutCompositing,CISourceOverCompositing, CIStraightenFilter, CIStripesGenerator, CITemperatureAndTint, CIToneCurve, CIVibrance, CIVignette, and CIWhitePointAdjust

iBooks

• iBooks 1.2.2 may fail to display some text or images in books. Please update to iBooks 1.3 in the App Store.

iCloud Backup

• If you enable iCloud Backup, automatic backup with iTunes when syncing will be disabled. We also suggest that you manually back up your device with iTunes. Backups made with earlier versions of iOS 5 beta will soon become incompatible, and will no longer be available. It is strongly advised you upgrade to this version of the iOS 5 beta in order to continue backing up your devices.

iCloud Storage

• NEW: Starting in iOS 5 beta 7, the requirements for specifying container identifier strings in your application’s entitlements have changed. Each container identifier that does not include a wildcard character must exactly match the bundle identifier of an application published using the same team ID as your application. You are not required to include an entitlement that matches your app’s own bundle identifier; for example, a lite and pro version of your app could both specify the pro app’s bundle identifier to share the same container. The requirements for container identifiers that include wildcard characters have not changed, but you may need to update existing wildcard identifiers after changing any non-wildcard identifiers in your application’s entitlements to match the new rules.
• NEW: In this beta of iOS 5.0 the number of times an app can synchronize in quick succession with the servers has been reduced. If you are debugging your app and want to see whether your synchronize requests are being throttled, you can call the -[NSUbiquitousKeyValueStore _printDebugDescription] method directly in gdb. Please note that -[NSUbiquitousKeyValueStore _printDebugDescription] is an SPI so you are strongly advised not to use it in your app.
• On KVS, the per-key limit has been raised to 64Kb (to match the per-app limit); and the maximum number of keys has been raised to 256.
• During the iOS 5 beta period, any documents stored on the servers might be purged periodically before GM. Therefore, it is highly recommended that you do not store any critical documents or information on the servers.
• Provisioning Profiles no longer need to be enabled for iCloud in the iOS Provisioning Portal. All newly generated provisioning profiles are now automatically enabled for iCloud. If you are using an Xcode managed Team Provisioning Profile, click refresh in the Xcode Organizer to obtain a new iCloud-enabled profile. To enable all other provisioning profiles for iCloud, simply regenerate your profiles in the iOS Provisioning Portal.
• If your application is using the NSMetadataQuery class, you must set a predicate, the predicate is now honored. But the predicate is an NSPredicate-style predicate, not a Spotlight-style predicate an example of this is that you must use LIKE instead of = for wild card matching. The differences are defined in more detail at:http://developer.apple.com/library/mac/#documentation/Cocoa/Conceptual/Predicates/Articles/pSpotlightComparison.html#//apple_ref/doc/uid/TP40002370-SW1
• In this beta, the setSortDescriptors: method of NSMetadataQuery is not supported.
• To use iCloud prior to beta 5, you had to manually specify various container identifiers (your application’s Display set) within an Entitlements file for both of your Mac OS X and iOS projects.Starting in beta 5, to enable iCloud storage within your apps, simply click the “Enable Entitlements” checkbox in the Summary pane of your project. Xcode will create a custom entitlements file for your project that automatically includes your Team ID. You can add additional iCloud Container values as required by your application. (Note that you must regenerate your existing provisioning profiles, either with Xcode or in the iOS Provisioning Portal, to use iCloud storage.)If you specify a custom identifier string for your iCloud Key-Value Store or iCloud Container entitlement values, you no longer need to prepend your Team ID to the beginning of the string. Xcode will prepend your Team ID to these entries automatically
• The container identifier string you pass to the URLForUbiquityContainerIdentifier: method of NSFileManager MUST include the team ID at the beginning of the string. As a convenience, if you passnil, Foundation uses the first document container ID specified in your app’s entitlements.
• There are issues using the Cloud Storage document API in conjunction with protected data which can lead to data corruption.
• In this beta, file presenters (objects that adopt the NSFilePresenter protocol) do not receive some of the messages that they’re supposed to receive, especially:
  • presentedSubitemDidAppearAtURL:
  • presentedSubitemDidChangeAtURL:

  You can workaround this by implementing the relinquishPresentedItemToWriter: method and checking to see if the writer actually wrote when your file presenter reacquires.

  File presenters do receive presentedItemDidChange: messages in this beta.

• While reporting a bug related to the iCloud storage interfaces, please include the logs collected during your debugging session. To generate these logs, you must install a special debug profile on your device.The debug profile can be obtained from http://connect.apple.com. This profile enables the generation of debug logs that are needed to diagnose any problems using iCloud storage. The instructions to collect the logs are:
  1. Install the profile. (The easiest way to do this is to mail it to yourself and open the attachment on their device.)
  2. Reproduce the bug.
  3. Sync with iTunes to pull the logs off your device.
  4. Attach the logs to your bug report. You can find the logs in ~/Library/Logs/CrashReporter/MobileDevice/DeviceName/DiagnosticLogs.

  These logs can grow large very quickly, so you should remove the profile after you have reproduced the problem and pulled the logs for the bug report.

• File names are case-insensitive in OS X but case-sensitive in iOS. This can lead to problems when syncing files between the two. You should take steps on iOS to avoid creating files whose names differ only by case.

Find My iPhone

• After OTA update Find My iPhone does not work. To make it functional you can toggle the the Find My iPhone from OFF to ON in Settings.

GameKit

• NEW: Auto-matching with the Turn-based view controller does not work. Invites or the direct auto-match API can be used as a workaround.
• Match data for turn based matches is currently limited to 4 KB of data.
• FIXED: Events will be passed to the delegate whenever a turn is made on a match, instead of just when it becomes the local player’s turn.

iMessage

• iMessage beta 1 will be unable to communicate with iMessage users on beta 2 or later.
• FIXED:Setup Assistant does not provide AppleID password as an input for the FaceTime in iMessage.

interface Builder

• FIXED: When editing the value of a constraint in the inspector, the constraint remains selected, and the outline view continues to show the constraint as selected.
• In XCode 4.2 when copying views (either a single view or multiple views), both the user defined constraints directly on the selected view and the user defined constraints between the views being copied are copied to the pasteboard.
• Changing the segment style of an NSSegmentedControl object to “Automatic” might crash in documents using Cocoa Auto Layout. To workaround the issue use an explicit segment style such as Round or Textured, and at runtime, change the segment style to automatic using the setSegmentStyle: method.

iTunes

• NEW: When trying to restore an iPhone 3GS or iPod touch 3rd generation device running Beta 6 to Beta 7 using iTunes, you will have to set the device into DFU or you can OTA update to Beta 7. To enter DFU mode you will have to:
  1. Connect the device to USB on your Mac.
  2. Turn the device off.
  3. Launch iTunes on your Mac.
  4. Hold down the Home and Power buttons for 10 seconds.
  5. Continue holding the Home button but let go of the Power button.
  6. Hold Home button for 13 seconds or until the device shows up in iTunes.
• The version of iTunes that comes with beta 7 cannot sync devices that have the beta 6 software installed. To avoid this problem, do the following:
  1. Sync any devices that have beta 6 installed to the version of iTunes that came with beta 6.
  2. Upgrade iTunes to the version that comes with beta 7.
  3. Connect the device and install the beta 7 software. (Understand that you might see a failure to sync error when you first connect the device.)
  4. After installing the beta 7 software, restore from your the backup you made in step 1.

Mail

• When changing the host name of an email account in settings, blank messages may be seen in the unified inbox. As a workaround, delete and re-add the account instead of changing its host name.

Music Player

• When deleting a song or video from Music/Videos on the device it crashes the app.

OpenGLES

• FIXED: After the lighting stage, whether lighting is enabled or not, the resulting color values are not clamped in GLKit/GLKEffects with either GLKLightingTypePerVertex or GLKLightingTypePerPixel set on the effect. As a result it is not uncommon to see differences in lighting between the two, especially when multiple lights are enabled. This differs from OpenGLES 1.1 which clamps color values after the lighting stage regardless of whether or not lighting is enabled.

OTA Software Update

• Users who installed iOS 5 beta 6 over the air from iOS 5 beta 3 must first erase all content and settings by choosing Settings > General > Reset > Erase All Content and Settings in order to install iOS 5 beta 7 over the air. This only impacts users who did not update to iOS 5 beta 4.
• If you are doing an OTA software update, you will need to re-sync your photos with iTunes.”
• FIXED: There may be some cases where purchases from the App Store or iTunes Store appear to be stalled because the device is downloading something else in the background. A workaround is to disconnect the device from power (unplug the device).
• NEW: If you have a passcode set, it must be removed before updating to seed 7 from previous seeds. It can be re-enabled after the update is complete. Failure to do so may require iMessage to be re-enabled in settings.

Reminders

• FIXED: If reminders syncing is enabled for a Yahoo account and there is no reminders collection on the server, it will continually get recreated by the phone. Due to a Yahoo server bug, that collection will show up as an event calendar.

Security

• In iOS 5.0 signing of certificates with MD5 signatures is not supported. Please ensure that certificates use signature algorithms based on SHA1 or SHA2.

Simulator

• Location services are not functional in iOS 4.3 simulator running on Mac OS 10.7 with Xcode 4.2.

Springboard

• Push and local notifications for apps appear in the new Notification Center in iOS 5. Notification Center displays notifications that are considered “unread.” In order to accommodate push and local notifications that have no “unread” status, developers can use their application badge count to trigger a clearing of notifications from Notification Center. When an application clears its badge count (by setting it to zero), iOS 5 will clear its notifications from Notification Center.

UI Automation

• There is a known issue when using the performTaskOnHost API in a UI Automation script. If the task being performed with the API outputs excessively (say, thousands of lines of text) to standard out or standard error, the task may deadlock until the timeout is reached, at which point it will throw a javascript exception.
• The lock() and unlock() functions of UIATarget have been replaced with the lockForDuration(<seconds>) function.
• Starting in iOS 5 beta 2, you can now trigger the execution of an UI Automation script on an iOS device from the host terminal by using the instruments tool. The command is:
  • instruments -w <device id> -t <template> <application>
• When using the cli instruments for UI Automation you can now target the default Automation Template and pass the script and results path into the tool as environment variable options. For example:
  • instruments -w <device id> -t /Developer/Platforms/iPhoneOS.platform/Developer/Library/Instruments/PlugIns/AutomationInstrument.bundle/Contents/Resources/Automation.tracetemplate <application> -e UIASCRIPT <script> -e UIARESULTSPATH <results path>

UIKit

• In iOS 5.0 UIPickerView doesn’t send its pickerView:didSelectRow:inComponent: delegate message due to a programatic selection.
• Starting in iOS 5 beta 3, the exclusiveTouch property of UIControl has returned to its original default value of NO.
• Returning nil from the tableView:viewForHeaderInSection: method (or its footer equivalent) is no longer sufficient to hide a header. You must override tableView:heightForHeaderInSection:and return 0.0 to hide a header.
• In the iOS 5 beta, the UITableView class has two methods to move one cell from one row to another with defined parameters. These APIs are:
  • moveSection:toSection:
  • moveRowAtIndexPath:toIndexPath:
• Using the UIWebView class in Interface Builder, setting transparent background color is possible in iOS 5. Developers compiling against the new SDK can check their XIB for the UIWebView transparent setting.
• In the iOS 5 beta, the UINavigationBar, UIToolbar, and UITabBar implementations have changed so that the drawRect: method is not called on instances of these classes unless it is implemented in a subclass. Apps that have re-implemented drawRect: in a category on any of these classes will find that the drawRect: method isn’t called. UIKit does link-checking to keep the method from being called in apps linked before iOS 5 but does not support this design on iOS 5 or later. Apps can either:
  • Use the customization API for bars that in iOS 5 and later, which is the preferred way.
  • Subclass UINavigationBar (or the other bar classes) and override drawRect: in the subclass.
• The indexPathForRow:inSection:, section, and row methods of NSIndexPath now use NSInteger instead of NSUInteger, so that these types match with methods defined on UITableView.
• We have changed the behavior of scrollToRowAtIndexPath:atScrollPosition:animated: such that UITableViewScrollPositionTop and UITableViewScrollPositionBottom now adjust for the top and bottom portions of the contentInset property.
• NEW: In releases prior to iOS 5.0, the UIPopoverController class would unconditionally set the autoresizing masks of view controllers which were the content view controller of the popover controller. It would also unconditionally set the autoresizing masks of the views of view controllers pushed on to a UINavigationController object which was the content view controller of the popover controller.In iOS 5.0, the UIPopoverController class will no longer do this for applications linked on iOS 5.0 or later. Developers should ensure that the autoresizing masks of views are set properly to allow for arbitrary resizing within any container, not just popovers. A mask of (UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight) would not be unreasonable.
• The completion handler for saveToURL:forSaveOperation:completionHandler: is now being called outside of the coordinated write block, where it used to be called inside.
• FIXED: The autosaveWithCompletionHandler: method will now only be called for period-based saves and it is safe to return without saving. Documents must save, though, if thesaveToURL:forSaveOperation:completionHandler: method is invoked.

Safari and WebKit

• In iOS 5, a new inherited CSS property, -webkit-overflow-scrolling, is available. The value touch allows the web developer to opt in to native-style scrolling in an overflow:scroll element. The default value for this property is auto, which allows single-finger scrolling without momentum.
• The WebKit framework has picked up a newer WebKit engine, which closely matches Safari 5.1. Some areas to be aware of with the new WebKit framework on iOS:
  • There is a new HTML5-compliant parser.
  • Text layout width may change slightly because word-rounding behavior now has floating-point-based precision.
  • There is improved validation of the <input type=number> form field, which includes removing leading zeros and number formatting.
  • Touch events are now supported on input fields.
  • window.onerror is now supported.
  • There is a new user agent that does not have locale information in the User Agent string.
  • URLs are now canonicalized by making the scheme all lowercase. If a fake URL is used to pass information from a UIWebView back to native code, make sure that the scheme is always lowercase, or that the native code compares the scheme in a case-insensitive manner.

Wi-Fi Syncing

• In iOS 5 beta 4 and later, wireless syncing is now available on Windows as well as the Mac. (This support requires OS X 10.6.8 or Lion.) You will see an option to enable wireless syncing when you connect your device to iTunes with the USB cable. It is recommended you perform your initial sync with a cable after restoring your device.
  • Wireless syncing is triggered automatically when the device is connected to power and on the same network as the paired computer. Or, you can manually trigger a sync from iTunes or from Settings > General > iTunes Sync (same network as paired computer required).
  • If you find issues with apps, media and/or photos synced to your device, you can reset then resync. From Settings > General > Reset, choose Erase all Content and Settings. Then reconnect to iTunes and sync again.

Xcode

• NEW: Starting with Xcode 4.2 in iOS 5.0 beta 7, support to run and debug applications in the iOS 4.3 Simulator and on devices with iOS versions older than 4.2 is made optional and installed on demand. This support is no longer shipped as part of the core tools packaging, and made available for download and installation through the “Downloads” pane of the Xcode Preferences panel. A valid iOS developer ADC account is required to obtain this content.To obtain the iOS 4.3 Simulator, select the “More Simulators…” item from the Run Destinations popup in the main toolbar. This will present the Downloads pane of the Preferences with UI to initiate the installation of the simulator.To obtain iOS device support for pre-iOS 4.2 devices, connect a device and activate it for development in the Organizer. Xcode will provide a prompt to initiate the download of the device support components.If the Xcode 4.2 in iOS 5.0 beta 7 is installed over a previous Xcode 4.2 beta or Xcode 4.1, the iOS 4.3 Simulator and device support from the previous install will already be present, and the additional components will display as “Installed” in the Downloads pane of the Xcode Preferences.The installation packages for the downloaded components will be stored in ~Library/Developer/Xcode. When a new version of Xcode (beta or GM) will be installed, subsequent requests to install these components will use the local packages without requiring a new download.
• In some cases, Xcode 4.2 Organizer does not display a device that is in restore mode. As a workaround you can use iTunes to restore.
• In iOS 5 beta 5, iOS Simulator is not compatible with previous releases of the iCloud Developer Seed for OS X. It is highly recommended that you update to the latest iCloud Developer Seed to ensure compatibility.
• iOS 5.0 SDK supports both iOS 4.3 and iOS 5.0 simulators.

Apple on Friday release iOS 5 beta 6 to developers. The new build is available as a 144MB over-the-air (OTA) update for developers with iOS 5 beta 3 and later installed on their iPhone, iPads or iPod touch devices. Of note, Apple does not recommend wiping your device prior to updating with this new build, as it did with beta 5. In addition, Apple also released updated builds of iTunes (10.5 beta 6) and Xcode (4.2 preview 3). The full change log for iOS 5 beta 6 follows below.

Thanks, Jean!

Notes and Known Issues

The following issues relate to using the 5.0 SDK to develop code.

Accounts

• When creating an iCloud account, you can use any Apple ID as long as it is a full email address and not a MobileMe account. If you have a MobileMe account, you can move that account to iCloud. You can find more information on iCloud at: http://developer.apple.com/icloud
• FIXED: When setting up an iCloud or MobileMe account using the setup assistant and leaving Find My iPhone on, it might actually turn Find my iPhone off after the setup. Please verify in Settings/Mail, Contacts, Calendar/YourAccount that Find my iPhone is toggled On after leaving the setup assistant.
• FIXED: Enabling iCloud services in Setup Assistant may not always be saved correctly. After completing Setup Assistant you should visit Settings > iCloud to verify the state of the iCloud account. If you have multiple iCloud or MobileMe accounts configured on the device you should also visit each of those accounts in Settings > Mail, Contacts, Calendar to verify each account.
• FIXED: It is recommended that you disable Bookmarks on multiple accounts. If they are enabled, the results might be undefined.

AirPlay

• Starting in iOS 5, video content in applications and websites are AirPlay-enabled by default.
• iOS 5 supports AirPlay of video via AV Foundation.

Apple TV

• Apple TV Software beta enables users to mirror the contents of an iPad 2 to an Apple TV (2nd generation) using AirPlay.

Apple TV Software beta is being provided to test the latest AirPlay functionality with your iOS 5 apps and web sites. If you wish to install Apple TV Software beta on your device, you must first register your device UDID in the iOS Developer Program Portal.
• Apple TV may return to the main menu when exiting a TV show played via Home Sharing.
• Music playlists are inaccessible via Home Sharing.

Binary Compatibility

• On applications linked against the iOS 5.0 SDK, scroll view content offsets will no longer be rounded to integral pixels during a pinch gesture.

Calendar

• Birthday calendars are not currently available via the icloud.com website or in Windows. They will be available in a future release.
• FIXED: The default calendar is still the On My iPhone calendar despite setting up an iCloud account during Setup Assistant. As a workaround, reset the default Calendar after finishing Setup Assistant in Settings > Mail, Contacts, Calendar > Default Calendar.
• FIXED: Pushing iCloud Calendar data is not working in iOS. To sync your iCloud Calendar, launch the Calendar app or refresh the calendars manually using the Calendars button in the top left corner.

Core Image

• Several filters have been added since beta 1. The current list now includes the following filters:CIAdditionCompositing, CIAffineTransform, CICheckerboardGenerator, CIColorBlendMode, CIColorBurnBlendMode, CIColorControls, CIColorCube, CIColorDodgeBlendMode, CIColorInvert,CIColorMatrix, CIColorMonochrome, CIConstantColorGenerator, CICrop, CIDarkenBlendMode, CIDifferenceBlendMode, CIExclusionBlendMode, CIExposureAdjust, CIFalseColor, CIGammaAdjust,CIGaussianGradient, CIHardLightBlendMode, CIHighlightShadowAdjust, CIHueAdjust, CIHueBlendMode, CILightenBlendMode, CILinearGradient, CILuminosityBlendMode,CIMaximumCompositing, CIMinimumCompositing, CIMultiplyBlendMode, CIMultiplyCompositing, CIOverlayBlendMode, CIRadialGradient, CISaturationBlendMode, CIScreenBlendMode,CISepiaTone, CISoftLightBlendMode, CISourceAtopCompositing, CISourceInCompositing, CISourceOutCompositing, CISourceOverCompositing, CIStraightenFilter, CIStripesGenerator,CITemperatureAndTint, CIToneCurve, CIVibrance, CIVignette, and CIWhitePointAdjust

GameKit

• Match data for turn based matches is currently limited to 4 KB of data.
• NEW: Events will be passed to the delegate whenever a turn is made on a match, instead of just when it becomes the local player’s turn.
• FIXED: When logging in to Game Center, the password may clear and login may not complete. Trying a second time will succeed.
• FIXED: In this beta, GameKit Invites may fail. As a workaround, try restarting the device.

iBooks

• iBooks 1.2.2 may fail to display some text or images in books. Please update to iBooks 1.3 in the App Store.

iCloud Backup

• As this is beta software, it is recommended that you do not use the iCloud services to store any critical data or information. If you enable iCloud Backup, automatic backup with iTunes when syncing will be disabled. We also suggest that you manually back up your device with iTunes. Backups made with earlier versions of iOS 5 beta will soon become incompatible, and will no longer be available. It is strongly advised you upgrade to this version of the iOS 5 beta in order to continue backing up your devices. If you encounter errors restoring from a backup, or enabling a backup more than one hour after signing into iCloud, try deleting your iCloud account from Settings and adding it back. If errors persist, please try erasing your device and initiating the restore again.

iCloud Storage

• NEW: If you call either stringByResolvingSymlinksInPath or stringByStandardizingPath on a path descended from your container, you’ll never be able to use the result to successfully perform a coordinated read.
• NEW: On KVS, the per-key limit has been raised to 64Kb (to match the per-app limit); and the maximum number of keys has been raised to 256.
• During the iOS 5 beta period, any documents stored on the servers might be purged periodically before GM. Therefore, it is highly recommended that you do not store any critical documents or information on the servers.

• There are issues using the Cloud Storage document API in conjunction with protected data which can lead to data corruption.
• FIXED: In this beta, document-based applications cannot always detect when files change, move, or are deleted out from underneath them.
• In this beta, file presenters (objects that adopt the NSFilePresenter protocol) do not receive some of the messages that they’re supposed to receive, especially:
  • presentedItemDidChange
  • presentedSubitemDidAppearAtURL:
  • presentedSubitemDidChangeAtURL:

  You can workaround this by implementing the relinquishPresentedItemToWriter: method and checking to see if the writer actually wrote when your file presenter reacquires. You can also use FSEvents to observe file system changes

• In this beta, messages about changes to files in a directory are not getting delivered to objects that adopt the NSFilePresenter protocol.
• While reporting a bug related to the iCloud storage interfaces, please include the logs collected during your debugging session. To generate these logs, you must install a special debug profile on your device.The debug profile can be obtained from http://connect.apple.com.

  These logs can grow large very quickly, so you should remove the profile after you have reproduced the problem and pulled the logs for the bug report.

• File names are case-insensitive in OS X but case-sensitive in iOS. This can lead to problems when syncing files between the two. You should take steps on iOS to avoid creating files whose names differ only by case.

iMessage

• iMessage beta 1 will be unable to communicate with iMessage users on beta 2 or later.
• NEW:Setup Assistant does not input AppleID password in for FaceTime of iMessage.

interface Builder

• NEW:The top-level views in a document that uses autolayout cannot have width and height constraints added. To workaround this you can add desired width or height constraint manually in code.
• NEW:In Interface Builder documents using autolayout and constraints that Xcode generates cannot be deleted. You can “delete” these constraints by creating a user constraint for the behavior you are expecting. For example, if you drag out a button and Xcode generates a leading constraint to the button’s superview, and you wanted a trailing edge to the superview constraint, creating one manually using “Add Constraint => Trailing Constraint to Superview” would remove the leading edge to superview constraint.
• NEW:It is known that equal widths/heights constraints can be broken on views that fill a container when resizing the window. If you resize the window and a equal widths/height constraint is broken, re-adding it will properly adjust the window to accommodate the constraint.
• NEW: When editing the value of a constraint in the inspector, the constraint remains selected, and the outline view continues to show the constraint as selected.
• NEW:In XCode 4.2 when copying views (either a single view or multiple views), both the user defined constraints directly on the selected view and the user defined constraints between the views being copied are copied to the pasteboard.
• NEW:In Xcode 4.2 for a document using Cocoa Auto Layout, “Select All” in the canvas no longer selects the constraints and subviews of the edited view. If a view is selected, it will only select views. If a constraint is selected, “Select All” will select all constraints.
• NEW:Changing the segment style of an NSSegmentedControl to “Automatic” might crash in documents using Cocoa Auto Layout. To workaround the issue use an explicit segment style such as Round or Textured, and at runtime, change the segment style to automatic using -[NSSegmentedCell setSegmentStyle:]

iPod

• FIXED: When using the volume buttons on the device, or on headphones, the volume slider in the UI of applications may not update even though the volume level has changed.

iTunes

• The version of iTunes that comes with beta 5 cannot sync devices that have the beta 4 software installed. To avoid this problem, do the following:
  1. Sync any devices that have beta 4 installed to the version of iTunes that came with beta 4.
  2. Upgrade iTunes to the version that comes with beta 5.
  3. Connect the device and install the beta 5 software. (Understand that you might see a failure to sync error when you first connect the device.)
  4. After installing the beta 5 software, restore from your the backup you made in step 1.
• Videos purchased from the iTunes Store do not play on a 2nd generation AppleTV over AirPlay with iTunes 10.5.

Mail

• When changing the host name of an email account in settings, blank messages may be seen in the unified inbox. As a workaround, delete and re-add the account instead of changing its host name.

OTA Software Update

• If you are doing an OTA software update, you will need to re-sync your photos with iTunes.”

Photos

• FIXED: When restoring photo libraries from an iTunes backup, some photos may not appear in the Photos application after restore. Please back up your photos before updating to iOS Beta 5.

Reminders

• NEW: If reminders syncing is enabled for a Yahoo account and there is no reminders collection on the server, it will continually get recreated by the phone. Due to a Yahoo server bug, that collection will show up as an event calendar.

Simulator

• Location services are not functional in iOS 4.3 simulator running on Mac OS 10.7 with Xcode 4.2.

Springboard

• Push and local notifications for apps appear in the new Notification Center in iOS 5. Notification Center displays notifications that are considered “unread.” In order to accommodate push and local notifications that have no “unread” status, developers can use their application badge count to trigger a clearing of notifications from Notification Center. When an application clears its badge count (by setting it to zero), iOS 5 will clear its notifications from Notification Center.
• FIXED: The UIPrerenderedIcon key (in the Info.plist file) is not honored in this beta.

StoreKit

• FIXED: In-App purchase will not work for developers testing their apps with the iTunes Sandbox.

UI Automation

• NEW: There is a known issue when using the performTaskOnHost API in a UI Automation script. If the task being performed with the API outputs excessively (say, thousands of lines of text) to standard out or standard error, the task may deadlock until the timeout is reached, at which point it will throw a javascript exception.
• The lock() and unlock() functions of UIATarget have been replaced with the lockForDuration(<seconds>) function.
• Starting in iOS 5 beta 2, you can now trigger the execution of an UI Automation script on an iOS device from the host terminal by using the instruments tool. The command is:
  • instruments -w <device id> -t <template> <application>
• When using the cli instruments for UI Automation you can now target the default Automation Template and pass the script and results path into the tool as environment variable options. For example:
  • instruments -w <device id> -t /Developer/Platforms/iPhoneOS.platform/Developer/Library/Instruments/PlugIns/AutomationInstrument.bundle/Contents/Resources/Automation.tracetemplate <application> -e UIASCRIPT <script> -e UIARESULTSPATH <results path>

UIKit

• Starting in iOS 5 beta 3, the exclusiveTouch property of UIControl has returned to its original default value of NO.
• Returning nil from the tableView:viewForHeaderInSection: method (or its footer equivalent) is no longer sufficient to hide a header. You must override tableView:heightForHeaderInSection: and return0.0 to hide a header.
• In the iOS 5 beta, the UITableView class has two methods to move one cell from one row to another with defined parameters. These APIs are:
  • moveSection:toSection:
  • moveRowAtIndexPath:toIndexPath:
• Using the UIWebView class in Interface Builder, setting transparent background color is possible in iOS 5. Developers compiling against the new SDK can check their XIB for the UIWebView transparent setting.
• In the iOS 5 beta, the UINavigationBar, UIToolbar, and UITabBar implementations have changed so that the drawRect: method is not called on instances of these classes unless it is implemented in a subclass. Apps that have re-implemented drawRect: in a category on any of these classes will find that the drawRect: method isn’t called. UIKit does link-checking to keep the method from being called in apps linked before iOS 5 but does not support this design on iOS 5 or later. Apps can either:
  • Use the customization API for bars that in iOS 5 and later, which is the preferred way.
  • Subclass UINavigationBar (or the other bar classes) and override drawRect: in the subclass.
• The indexPathForRow:inSection:, section, and row methods of NSIndexPath now use NSInteger instead of NSUInteger, so that these types match with methods defined on UITableView.
• Touch events are not getting forwarded to the view in the cameraOverlayView property of UIImagePickerController.
• We have changed the behavior of scrollToRowAtIndexPath:atScrollPosition:animated: such that UITableViewScrollPositionTop and UITableViewScrollPositionBottom now adjust for the top and bottom portions of the contentInset property.
• NEW: In releases prior to iOS 5.0, the UIPopoverController class would unconditionally set the autoresizing masks of view controllers which were the content view controller of the popover controller. It would also unconditionally set the autoresizing masks of the views of view controllers pushed on to a UINavigationController object which was the content view controller of the popover controller.In iOS 5.0, the UIPopoverController class will no longer do this for applications linked on iOS 5.0 or later. Developers should ensure that the autoresizing masks of views are set properly to allow for arbitrary resizing within any container, not just popovers. A mask of (UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight) would not be unreasonable.
• The completion handler for saveToURL:forSaveOperation:completionHandler: is now being called outside of the coordinated write block, where it used to be called inside.
• NEW: The autosaveWithCompletionHandler: method is now called only for period-based saves and it is safe to return without saving. Documents must save, though, if thesaveToURL:forSaveOperation:completionHandler: method is invoked.

Safari and WebKit

• In iOS 5, a new inherited CSS property, -webkit-overflow-scrolling, is available. The value touch allows the web developer to opt in to native-style scrolling in an overflow:scroll element. The default value for this property is auto, which allows single-finger scrolling without momentum.
• FIXED: In beta 5, accessing sites that use client side SSL certificates does not work and may cause the application to crash.
• The WebKit framework has picked up a newer WebKit engine, which closely matches Safari 5.1. Some areas to be aware of with the new WebKit framework on iOS:
  • There is a new HTML5-compliant parser.
  • Text layout width may change slightly because word-rounding behavior now has floating-point-based precision.
  • There is improved validation of the <input> form field, which includes removing leading zeros and number formatting.
  • Touch events are now supported on input fields.
  • window.onerror is now supported.
  • There is a new user agent that does not have locale information in the User Agent string.
  • FIXED: URLs are now canonicalized by making the scheme all lowercase. If a fake URL is used to pass information from a UIWebView back to native code, make sure that the scheme is always lowercase, or that the native code compares the scheme in a case-insensitive manner.

Wi-Fi Syncing

• In iOS 5 beta 4 and later, wireless syncing is now available on Windows as well as the Mac. (This support requires OS X 10.6.8 or Lion.) You will see an option to enable wireless syncing when you connect your device to iTunes with the USB cable. It is recommended you perform your initial sync with a cable after restoring your device.
  • Wireless syncing is triggered automatically when the device is connected to power and on the same network as the paired computer. Or, you can manually trigger a sync from iTunes or from Settings > General > iTunes Sync (same network as paired computer required).
  • If you find issues with apps, media and/or photos synced to your device, you can reset then resync. From Settings > General > Reset, choose Erase all Content and Settings. Then reconnect to iTunes and sync again.
• FIXED: In some cases, your device may fail to sync contacts, calendars and account settings, or back up to iTunes. If this happens, reboot your device and re-sync.

Xcode

• In some cases, Xcode 4.2 Organizer does not display a device that is in restore mode. As a workaround you can use iTunes to restore.
• In iOS 5 beta 5, iOS Simulator is not compatible with previous releases of the iCloud Developer Seed for OS X. It is highly recommended that you update to the latest iCloud Developer Seed to ensure compatibility.
• iOS 5.0 SDK supports both iOS 4.3 and iOS 5.0 simulators.
• FIXED: Xcode fails to build a Page-based template. You can work around this issue by adding the Core Graphics framework to your project.

Apple just pushed iOS 5 beta 5 out to developers and wouldn’t you know, we’ve got the full change log for you to feast your eyes on. Hit the jump for all the iOS 5 changes you can handle.

Thanks, Jean!

Notes and Known Issues

The following issues relate to using the 5.0 SDK to develop code.

Accounts

• When creating an iCloud account, you can use any Apple ID as long as it is a full email address and not a MobileMe account. If you have a MobileMe account, you can move that account to iCloud. You can find more information on iCloud at: http://developer.apple.com/icloud
• When setting up an iCloud or MobileMe account using the setup assistant and leaving Find My iPhone on, it might actually turn Find my iPhone off after the setup. Please verify in Settings/Mail, Contacts, Calendar/YourAccount that Find my iPhone is toggled On after leaving the setup assistant.
• NEW: Enabling iCloud services in Setup Assistant may not always be saved correctly. After completing Setup Assistant you should visit Settings > iCloud to verify the state of the iCloud account. If you have multiple iCloud or MobileMe accounts configured on the device you should also visit each of those accounts in Settings > Mail, Contacts, Calendar to verify each account.
• It is recommended that you disable Bookmarks on multiple accounts. If they are enabled, the results might be undefined.

AirPlay

• Starting in iOS 5, video content in applications and websites are AirPlay-enabled by default.
• iOS 5 supports AirPlay of video via AV Foundation.

Apple TV

• Apple TV Software beta enables users to mirror the contents of an iPad 2 to an Apple TV (2nd generation) using AirPlay. This beta software also enables Photo Stream on Apple TV so users can access photos stored in iCloud. Apple TV Software beta is being provided to test the latest AirPlay functionality with your iOS 5 apps and web sites. If you wish to install Apple TV Software beta on your device, you must first register your device UDID in the iOS Developer Program Portal.

Calendar

• Birthday calendars are not currently available via the icloud.com website or in Windows. They will be available in a future release.
• NEW: The default calendar is still the On My iPhone calendar despite setting up an iCloud account during Setup Assistant. As a workaround, reset the default Calendar after finishing Setup Assistant in Settings > Mail, Contacts, Calendar > Default Calendar.
• NEW: Pushing iCloud Calendar data is not working in iOS. To sync your iCloud Calendar, launch the Calendar app or refresh the calendars manually using the Calendars button in the top left corner.

Core Image

• Several filters have been added since beta 1. The current list now includes the following filters:CIAdditionCompositing, CIAffineTransform, CICheckerboardGenerator, CIColorBlendMode, CIColorBurnBlendMode, CIColorControls, CIColorCube, CIColorDodgeBlendMode, CIColorInvert,CIColorMatrix, CIColorMonochrome, CIConstantColorGenerator, CICrop, CIDarkenBlendMode, CIDifferenceBlendMode, CIExclusionBlendMode, CIExposureAdjust, CIFalseColor, CIGammaAdjust,CIGaussianGradient, CIHardLightBlendMode, CIHighlightShadowAdjust, CIHueAdjust, CIHueBlendMode, CILightenBlendMode, CILinearGradient, CILuminosityBlendMode,CIMaximumCompositing, CIMinimumCompositing, CIMultiplyBlendMode, CIMultiplyCompositing, CIOverlayBlendMode, CIRadialGradient, CISaturationBlendMode, CIScreenBlendMode,CISepiaTone, CISoftLightBlendMode, CISourceAtopCompositing, CISourceInCompositing, CISourceOutCompositing, CISourceOverCompositing, CIStraightenFilter, CIStripesGenerator,CITemperatureAndTint, CIToneCurve, CIVibrance, CIVignette, and CIWhitePointAdjust

GameKit

• Match data for turn based matches is currently limited to 4 KB of data.
• NEW: When logging in to Game Center, the password may clear and login may not complete. Trying a second time will succeed.
• NEW: In this beta, GameKit Invites may fail. As a workaround, try restarting the device.

iBooks

• iBooks 1.2.2 may fail to display some text or images in books. Please update to iBooks 1.3 in the App Store.

iCloud Backup

• As this is beta software, it is recommended that you do not use the iCloud services to store any critical data or information. If you enable iCloud Backup, automatic backup with iTunes when syncing will be disabled. We also suggest that you manually back up your device with iTunes. Backups made with earlier versions of iOS 5 beta will soon become incompatible, and will no longer be available. It is strongly advised you upgrade to this version of the iOS 5 beta in order to continue backing up your devices. If you encounter errors restoring from a backup, or enabling a backup more than one hour after signing into iCloud, try deleting your iCloud account from Settings and adding it back. If errors persist, please try erasing your device and initiating the restore again.

iCloud Storage

• During the iOS 5 beta period, any documents stored on the servers might be purged periodically before GM. Therefore, it is highly recommended that you do not store any critical documents or information on the servers.
• NEW: Provisioning Profiles no longer need to be enabled for iCloud in the iOS Provisioning Portal. All newly generated provisioning profiles are now automatically enabled for iCloud. If you are using an Xcode managed Team Provisioning Profile, click refresh in the Xcode Organizer to obtain a new iCloud-enabled profile. To enable all other provisioning profiles for iCloud, simply regenerate your profiles in the iOS Provisioning Portal.
• If your application is using the NSMetadataQuery class, you must set a predicate, even though the predicate itself is ignored.
• In this beta, the setSortDescriptors: method of NSMetadataQuery is not supported.
• FIXED: To use iCloud prior to beta 5, you had to manually specify various container identifiers (your application’s Display set) within an Entitlements file for both of your Mac OS X and iOS projects.Starting in beta 5, to enable iCloud storage within your apps, simply click the “Enable Entitlements” checkbox in the Summary pane of your project. Xcode will create a custom entitlements file for your project that automatically includes your Team ID. You can add additional iCloud Container values as required by your application. (Note that you must regenerate your existing provisioning profiles, either with Xcode or in the iOS Provisioning Portal, to use iCloud storage.)If you specify a custom identifier string for your iCloud Key-Value Store or iCloud Container entitlement values, you no longer need to prepend your Team ID to the beginning of the string. Xcode will prepend your Team ID to these entries automatically
• The container identifier string you pass to the URLForUbiquityContainerIdentifier: method of NSFileManager MUST include the team ID at the beginning of the string. As a convenience, if you pass nil, Foundation uses the first document container ID specified in your app’s entitlements.
• There are issues using the Cloud Storage document API in conjunction with protected data which can lead to data corruption.
• FIXED: In this beta, document-based applications cannot always detect when files change, move, or are deleted out from underneath them.
• In this beta, file presenters (objects that adopt the NSFilePresenter protocol) do not receive some of the messages that they’re supposed to receive, especially:
  • presentedItemDidChange
  • presentedSubitemDidAppearAtURL:
  • presentedSubitemDidChangeAtURL:

  You can workaround this by implementing the relinquishPresentedItemToWriter: method and checking to see if the writer actually wrote when your file presenter reacquires. You can also use FSEvents to observe file system changes

• In this beta, messages about changes to files in a directory are not getting delivered to objects that adopt the NSFilePresenter protocol.
• While reporting a bug related to the iCloud storage interfaces, please include the logs collected during your debugging session. To generate these logs, you must install a special debug profile on your device.The debug profile can be obtained from http://connect.apple.com. This profile enables the generation of debug logs that are needed to diagnose any problems using iCloud storage. The instructions to collect the logs are:
  1. Install the profile. (The easiest way to do this is to mail it to yourself and open the attachment on their device.)
  2. Reproduce the bug.
  3. Sync with iTunes to pull the logs off your device.
  4. Attach the logs to your bug report. You can find the logs in ~/Library/Logs/CrashReporter/MobileDevice/DeviceName/DiagnosticLogs.

  These logs can grow large very quickly, so you should remove the profile after you have reproduced the problem and pulled the logs for the bug report.

• NEW: File names are case-insensitive in OS X but case-sensitive in iOS. This can lead to problems when syncing files between the two. You should take steps on iOS to avoid creating files whose names differ only by case.

iMessage

• iMessage beta 1 will be unable to communicate with iMessage users on beta 2 or later.

iPod

• NEW: When using the volume buttons on the device, or on headphones, the volume slider in the UI of applications may not update even though the volume level has changed.

iTunes

• The version of iTunes that comes with beta 5 cannot sync devices that have the beta 4 software installed. To avoid this problem, do the following:
  1. Sync any devices that have beta 4 installed to the version of iTunes that came with beta 4.
  2. Upgrade iTunes to the version that comes with beta 5.
  3. Connect the device and install the beta 5 software. (Understand that you might see a failure to sync error when you first connect the device.)
  4. After installing the beta 5 software, restore from your the backup you made in step 1.
• Videos purchased from the iTunes Store do not play on a 2nd generation AppleTV over AirPlay with iTunes 10.5.

Location

• FIXED: The startMonitoringSignificantLocationChanges method of CLLocationManager does not cause applications to be resumed or launched in the background for significant location change updates. However, if a backup from a previous software version (where an application was monitoring significant location changes) is restored to the device, significant location change monitoring will continue to cause that application to be resumed or launched in the background.

Mail

• FIXED: Forwarding a message with attachments included does not attach the file and the message compose screen does not change from “Loading….”
• NEW: When changing the host name of an email account in settings, blank messages may be seen in the unified inbox. As a workaround, delete and re-add the account instead of changing its host name.

Music Library

• FIXED: Some songs are missing their album artwork after changing the device library via syncing.

OpenGL ES

• FIXED: In iOS 5.0 beta 4, several OpenGL ES extensions have been moved from the APPLE namespace to the EXT namespace, causing some API to be renamed. The altered extensions are EXT_color_buffer_half_float,EXT_occlusion_query_boolean, EXT_separate_shader_objects, EXT_shadow_samplers, EXT_texture_rg, EXT_debug_label, and EXT_debug_marker.

OTA Software Update

• If you are doing an OTA software update, you will need to re-sync your photos with iTunes.”

Personal HotSpot

• FIXED: In this beta, iPhone 4 device cannot join personal hotspot even if it is on due to a non functional Wi-Fi tethering on these devices.

Photos

• FIXED: If you apply red-eye adjustments in iOS, and import your image into the iPhoto seed build, the red-eye adjustments will not appear on that image in iPhoto. As a result, subsequent syncing of your image back to the iOS device from iPhoto will not show the red-eye adjustments.
• NEW: When restoring photo libraries from an iTunes backup, some photos may not appear in the Photos application after restore. Please back up your photos before updating to iOS Beta 5.

Simulator

• Location services are not functional in iOS 4.3 simulator running on Mac OS 10.7 with Xcode 4.2.

Springboard

• Push and local notifications for apps appear in the new Notification Center in iOS 5. Notification Center displays notifications that are considered “unread.” In order to accommodate push and local notifications that have no “unread” status, developers can use their application badge count to trigger a clearing of notifications from Notification Center. When an application clears its badge count (by setting it to zero), iOS 5 will clear its notifications from Notification Center.
• FIXED: iOS 5.0 terminates VoIP applications that are resumed in the background for incoming network traffic with extreme frequency. Developers are encouraged to make sure all incoming data is read from VoIP sockets to avoid this condition.
• NEW: The UIPrerenderedIcon key (in the Info.plist file) is not honored in this build.

StoreKit

• NEW: In-App purchase will not work for developers testing their apps with the iTunes Sandbox.

Twitter

• FIXED: When tweeting your location from Safari and exiting before the location can be established, the location arrow will stay in the status bar. The arrow can be removed by killing Safari from the task switcher.

UI Automation

• FIXED: Instruments overwrites the loaded automation script, even if another program is editing it.
• FIXED: The play and record buttons in the Automation instrument script editor may not work properly after targeting an application that was launched by a trace session and has ended. They may also not work if you target an application that was suspended. If you run into this problem and it persists, you may need to close and reopen the trace document to get back into a functional state.
• FIXED: When capturing actions into a script using the Automation instrument, interfaces with web views or table cells that contain a high number of off screen elements may take an extremely long time before returning with an expression.
• The lock() and unlock() functions of UIATarget have been replaced with the lockForDuration(<seconds>) function.
• Starting in iOS 5 beta 2, you can now trigger the execution of an UI Automation script on an iOS device from the host terminal by using the instruments tool. The command is:
  • instruments -w <device id> -t <template> <application>
• When using the cli instruments for UI Automation you can now target the default Automation Template and pass the script and results path into the tool as environment variable options. For example:
  • instruments -w <device id> -t /Developer/Platforms/iPhoneOS.platform/Developer/Library/Instruments/PlugIns/AutomationInstrument.bundle/Contents/Resources/Automation.tracetemplate <application> -e UIASCRIPT <script> -e UIARESULTSPATH <results path>

UIKit

• Starting in iOS 5 beta 3, the exclusiveTouch property of UIControl has returned to its original default value of NO.
• Returning nil from the tableView:viewForHeaderInSection: method (or its footer equivalent) is no longer sufficient to hide a header. You must override tableView:heightForHeaderInSection: and return0.0 to hide a header.
• In the iOS 5 beta, the UITableView class has two methods to move one cell from one row to another with defined parameters. These APIs are:
  • moveSection:toSection:
  • moveRowAtIndexPath:toIndexPath:
• Using the UIWebView class in Interface Builder, setting transparent background color is possible in iOS 5. Developers compiling against the new SDK can check their XIB for the UIWebView transparent setting.
• In the iOS 5 beta, the UINavigationBar, UIToolbar, and UITabBar implementations have changed so that the drawRect: method is not called on instances of these classes unless it is implemented in a subclass.

• The indexPathForRow:inSection:, section, and row methods of NSIndexPath now use NSInteger instead of NSUInteger, so that these types match with methods defined on UITableView.
• Touch events are not getting forwarded to the view in the cameraOverlayView property of UIImagePickerController.
• We have changed the behavior of scrollToRowAtIndexPath:atScrollPosition:animated: such that UITableViewScrollPositionTop and UITableViewScrollPositionBottom now adjust for the top and bottom portions of the contentInset property.

WebKit

• In iOS 5, a new inherited CSS property, -webkit-overflow-scrolling, is available. The value touch allows the web developer to opt in to native-style scrolling in an overflow:scroll element. The default value for this property is auto, which allows single-finger scrolling without momentum.

• The WebKit framework has picked up a newer WebKit engine, which closely matches Safari 5.1. Some areas to be aware of with the new WebKit framework on iOS:
  • There is a new HTML5-compliant parser.
  • Text layout width may change slightly because word-rounding behavior now has floating-point-based precision.
  • There is improved validation of the <input> form field, which includes removing leading zeros and number formatting.
  • Touch events are now supported on input fields.
  • window.onerror is now supported.
  • There is a new user agent that does not have locale information in the User Agent string.
  • NEW: URLs are now canonicalized by making the scheme all lowercase. If a fake URL is used to pass information from a UIWebView back to native code, make sure that the scheme is always lowercase, or that the native code compares the scheme in a case-insensitive manner.

Wi-Fi Syncing

• In iOS 5 beta 4 and later, wireless syncing is now available on Windows as well as the Mac. (This support requires OS X 10.6.8 or Lion.) You will see an option to enable wireless syncing when you connect your device to iTunes with the USB cable. It is recommended you perform your initial sync with a cable after restoring your device.
  • Wireless syncing is triggered automatically when the device is connected to power and on the same network as the paired computer. Or, you can manually trigger a sync from iTunes or from Settings > General > iTunes Sync (same network as paired computer required).
  • If you find issues with apps, media and/or photos synced to your device, you can reset then resync. From Settings > General > Reset, choose Erase all Content and Settings. Then reconnect to iTunes and sync again.
• In some cases, your device may fail to sync contacts, calendars and account settings, or back up to iTunes. If this happens, reboot your device and re-sync.
• FIXED: In some cases, syncing photos may result in only thumbnails on your device. If this happens, unsync Photos then re-sync again.

Xcode

• FIXED: In beta 4, device restores using Xcode were disabled. This has been fixed. Device restores are now enabled and work in Xcode.
• In some cases, Xcode 4.2 Organizer does not display a device that is in restore mode. As a workaround you can use iTunes to restore.
• In iOS 5 beta 5, iOS Simulator is not compatible with previous releases of the iCloud Developer Seed for OS X. It is highly recommended that you update to the latest iCloud Developer Seed to ensure compatibility.
• iOS 5.0 SDK supports both iOS 4.3 and iOS 5.0 simulators.
• NEW: Xcode fails to build a Page-based template. You can work around this issue by adding the Core Graphics framework to your project.

Last night we told you that iPhone OS 3.1 beta was released to developers and we’re pretty sure each and every one of them has had a pretty long night of playing, err, working with the new OS. Thankfully however, one anonymous tipster took a break from getting his or her 3.1 on to send us a quick breakdown of the changes so far in this build:

• Options for MMS are back on AT&T, but not sending or receiving.
• Non-destructive video editing means trimming a clip no longer saves over the original video but gives you the option to “Save as copy…”
• Voice Control now works over Bluetooth
• iPhone vibrates when moving icons
• Updated AT&T profile to 4.2
• Updated modem firmware to 5.08.01
• Improvements to OpenGL and Quartz
• APIs to allow third party apps to access videos and edit them
• You can now paste phone numbers into the phone app’s dialer. This wasn’t possible under 3.0
• While pasting phone numbers, a neat feature is that it will convert alphanumeric phone numbers into a real phone number (e.g. 1-800-FLOWERS becomes 1-800-356-9377)
• Calendar appointment popup notifications now display the “Location” field from the calendar entry
• Ability to save video attachments in emails to your camera roll

One item we notice to be MIA from the listed changes is a fix for the widespread squealing issue we broke last month. Considering Apple’s refusal to comment on the matter, perhaps the company is just hoping everyone forgets about it. Then again, maybe Cupertino will swoop in under the radar and sneak a fix past us in the release build. Yeah, we hope the latter is the case — and our ear drums hope so, too.

Thanks, Jeff / The iPhone Blog!
