Setelah Apple merilis iOS 7 Beta 6 secara mendadak pada Developer, kini Apple merilis beberapa catatan penting dan bugs apa saja yang terdapat pada iOS 7 beta 6 ini, Berikut adalah post note resmi dari Apple :
Introduction
iOS SDK 7.0 provides support for developing iOS apps, and it includes the complete set of Xcode tools, compilers, and frameworks for creating apps for iOS and OS X. These tools include the Xcode IDE and the Instruments analysis tool, among many others.
With this software you can develop apps for iPhone, iPad, and iPod Touch running iOS 7. You can also test your apps using the included iOS emulator, which support iOS 7. iOS SDK 7.0 requires a Mac computer running OS X 10.8.4 ( Mountain Lion ) or Later.
This version of iOS is intended for installation only on devices regostered with Apple Developer Program. Attempting to install this version of iOS in an un authorized manner could put your device in an unusable state.

Important Information about Music and Videos Libraries
This update addresses an issue with iTunes in the Cloud, where some purchases may download or play unexpected items. If you have any devices running previous versions of iOS 7 beta, you should:
1. Install iOS 7 beta 6
2. Install the Reset Music And Videos Libraries configuration profile from the iOS Dev Center.
3. From Setting > Music, Tap the Reset Media Library button.
4. Restart the devices.
Notes and Known Issues
The following issues relate to using iOS SDK 7.0 to develop code.
Address Book
Notes
- The classes in the AddressBookUI framework no explicitly disallow subclassing. For apps linked against the iOS 7 SDK, attempting to initialze a subclass of one of these classes return nil. For apps linked against older SDKs, the only behavior change is a warning logged to the console.
AirDrop
- As of Seed 4, privacy support for the AddressBookUI framework is reenabled for apps linked against the iOS 7 SDK. Apps linked against older SDKs are not changed. if your app uses any of the Address Book view controllers, you should verify that it still behaves as expected.
Notes
- AirDrop in iOS 7 Seed 2 or later is not compatible with AirDrop in iOS 7 Seed 1.
Your are logged in to iCloud.
- Contacts Only support requires that:
The sender and receiver have each other's Apple ID email addresses in Contacts on their devices.
AV Foundation
Notes
AVCaptureSession now uses your app's AVAudioSession by default.
Core Animation
Notes
When the UIViewGroupOpacity key is not present, the default value is now YES. The default was previously NO.
This mean That subviews of a transparent view will first be composited onto that transparent view, then the precomposited subtree will be drawn as a whole onto the background. A NO setting results in less expensive, but also less accurate, compositing: each view in the transparent subtree is composited onto what's underneath it. according to the parent's opacity, in the normal painter, algorithm order.
Exchange
Notes
In Seed 4 and late, the Exchange DeviceIdentifier has been changed back to the behavior of iOS 6 where it uses the serial number.
Fonts
Notes
New font line heights were introduced in Seed 4. If you had manually aligned your font in earlier seeds, it may move slightly up vertically in later seeds.
Foundation
Notes
NSPredicate *p = [NSComparisonPredicate
- An NSMetadataQuery with ubiquitous scope can now uses kMDItemContentTypeTree in predicates. For example:
preficateWithLeftExpression:[NSExpression
expressionForKeyPath:@"kMDItemContentTypeTree"]
rightExpression:[NSExpression expressionForConstantValue:@"public.frt"]
modifier:NSAnyPredicateModifier
type:NSLikePredicateOperatorType
option:o];
iCloud
- When called on results returned by queries with ubiquitous scopes, -[NSMetadataItemvalueForAttribute:NSMetadataItemDisplayNameKey] now produces the same value as -[NSURL getResourceValue: forKey: NSURLLocalizedNameKey], matching nonubiquitous queries.
Notes
- If you use iCloud Keychain with recovery, you may see a dialog indicating recovery has been disabled due to a server change. This is intentional. To reenable functionality, follow the instruction in the notification. If you see multiple alert or observe issues with reenabling recovery, pelase file a bug report.
- iCloud Keychain in iOS 7 Seed 3 or later is not Backward compatible with iOS 7 Seed 2 or OS X MAvericks Seed 2. If you had iCloud Keychain and/or Keychain Restore enabled from iOS 7 Seed 2, Both features are disabled upon updating to iOS 7 Seed 3 or later. After updating to iOS 7 Seed 3 or later, go to Settings . iCloud > Keychain and reenable iCloud Keychain on your devices. See OS X v10.9 Release Notes for more details.
- Activation Lock, a new feature of Find My iPhone, is turned on automatically when Find My iPhone is enabled on any device running iOS 7. Activation Lock requires users to enter their Apple ID and password to turn off Find My iPhone, sign out of iCloud, erase the device, or reactivate the device after an erase. It's important to do one of the following before transferring a device to a new user.
Sign our of iCloud
Turn off Activation Lock in Settings > iCloud > Find My iPhone.
Known Issues
Password field are not displayed in alert views for apps in landscape ( for example, Game Center authentication or In-App Purchase ) . Text entry still works, though you can't see what you are typing.
MapKit
Notes
If the calls to renderInContext on the layer backing an MKMapView are made off the main thread, they should be eliminated or moved to the main thread. Failure to do so can cause an app crash. Instead of using renderInContext, use the new MKMapSnapshotter APIs.
Media
Notes
iOS now remembers the last used media app across reboot and app crashes. Media apps that can receive remote control events should be prepared to be launched in the background and potentially receive a remote control event to begin playback .
Additionally, it's important that media apps monitor and handle the media server reset event, since the media app may receive a remote request to resume playback after a reset.
Notifications to monitor these media server events are available in AVAudioSession and proper handling is described in General Recommendations for handling kAudioSessionProperty_ServerDied.
Multipeer Connetivity
Notes the MCSession APIs function as they were presented ar WWDC. Major changes and enchancements include :
- The following new method on MCSession has been implemented: -(NSOutputStream *)startStreamWithName:(NSString *)streamName toPeer:(MCPeerID *)peerID error:(NSError **)error
- This delegate method has been implemented: - (void)session:(MCSession *)session didReceiveStream:(NSInputStream *)Stream withName:(NSString *) StreamName fromPeer:(MCPeerID *)peerID
- The following new method on MCSession has been implemented: - (NSProgress *)sendResourceAtURL:(NSURL *)resourceURL withName:(NSString *)resourceName toPeer:(MCPeerID *)peerID withCompletionHandler:(void(ˆ)(NSError *error))completionHandler
- The delegate method to start receiving a resource from remote peer has been implemented as: - (void)session:(MCSession *)session didStartReceivingResourceWithName:(NSString *)resourceName fromPeer:(MCPeerID *)peerID withProgress:(NSProgress *)progress
- The delegate method to finish receiving a resource from remote peer and save the content in a temporary location is implemented as: - (void)session:(MCSession *)session didFinishReceivingResourceWithName:(NSString *)resourceNamefromPeer:(MCPeerID *)peerID atURL:(NSURL *)localURL withError:(NSError *)error
- Note:
The app is responsible for moving the file to a permanent location within its sandbox.
- MCAdvertiserAssistant is a convenience class for implementing an Advertiser, which handles invitations and connections to anMCSession.
- MCSession has a new initWithPeer: method.
- sendResource has added "with"to the completionHandlers.
For more information on these APIs, watch the video for WWDC 2013 Session 708, "Nearby Networking with Multipeer Connectivity."
- The timeout has been removed from connectPeer:withNearbyConnectionData.
Multitasking
Notes
- AVAudioSession can no longer become active by apps in the background that wake due to Background Fecth, Background Transfer, and Remote Notification Events.
- The policy for the task completion API has changed back to match the iOS 6 behavior, but the time limit for task completion has decreased from 10 minutes in iOS 6.
Networking
Notes
- The cellular fallback technology present in previous seeds has been removed as of Seed 5.
- Two low-level networking APIs that used to return a MAC addres now return the fixed value 02:00:00:00:00:00. The APIs is question are sysctl (NET_RT_IFLIST) and ioctl (SIOCGICONF). Developers using the value of the MAC address should migrate to identifiers such as -[UIDevice identifierForVendor]. This change affects all apps running on iOS 7.
Objective-C Runtime
Notes
Due to changes in how the isa field is implemented, *self may change during enumeration ( for example, if the container is retained ).
Workaround : When implementing countByEnumeratingWithState, do not set state- >mutationsPtr = self.
Passbook
Notes
- As of iOS 7 Seed 4, Passbook has been addes support for major and minor fields to better match the rest of the iBeacon ecosystem. The new major and minor keys are independently variable optional alongside proximityUUID (rquired) in each dictionary in the beacons array.
- In previous versions of the iOS SDK, Passbook did not validate the back fields on passes completely. The validation rules have not changed, but validation is now including back fields. Please check the console log for additional logs.
- As of iOS 7 Seed 3, PKPassLibrarryDidCancelAddPasses is a new status code in the PKPassLibraryAddPassesStatus enum. It signifies that the user tapped Cancel in an add-passes alert.
Photos
Notes
Upon upgrading from an earlier seed, photo thumbnails in the Photos app will not appear for a short while.
Security
Notes
- -[UIDevice uniqueIdentifier] is no longer accepted in submissions to the App Store. In iOS 7, apps that are already on the store or on users device that call this removed API will no longer be returned the UDID. Instead, -[UIDevice uniqueIdentifier] will return a 40-character string starting with FFFFFFFF, followed by the hex value of -[UIDevice identifierForVendor]. It is important to consider how this will affect existing apps. Consider submitting updates that no longer access the UDID.
- iOS now requests user consent for apps to use audio input on all iOS 7 devcies. For devices sold in Chine, iOS will also request user consent for apps to use the camera hardware. The operating system will present the consent alert when you set the category of the istantiated AVAudioSession. The AVAudioSession categories that will present the alert are AVAudioSessionCategoryRecord and AVAudioSessionCatehoryPlayAnd Record. If the user doesn't allow access, The audio session data will be all zeros (Silence). For devices where camera access is requested and denied by the user, the video capture session is a black screen.
- The API gethostuuid () has been removed and will not be accepted for submission to the store, regardless of the targeted OS. For exiting apps running os iOS 7, the function will return auuid_t presentation of the vendor identifier (-[UIDeviceidentifierForVendor).
Siri
Notes
This seed includes development version of news male and female Siri voices for U.S English, French, and German.
Social
Notes
- Through iOS 6, when using TWTweetComposeViewController and SLComposeViewController (the latter only for Twitter and Weibo, but not Facebook), if the caller supplies a completionHandler, the supplied completionHandler is responsible for dismissing the view controller. As of iOS 7, if the app links against the iOS 7 SDK, the view controller will dismiss itself even if the caller supplies a completionHandler. To avoid this, the caller's completionHandler should not dismiss the view controller.
Springboard
- When using the iOS 6.1 SDK on OS X 10.8 Mountain Lion, if you use the iOS 5.0 or iOS 5.1 Legacy SDK in iOS Simulator, you will not be able to use Twitter features: attempting to sign in to Twitter vie the Settings pane will fail, and Twitter.framework will not work correctly. if you need to test Twitter features, you will need to choose either an iOS 6.1 or iOS 6.0 Simulator run destination, or you can test with iOS 5.x on a device.
Notes
- Active touches are no longer canceled when the user takes a screenshot.
Spire Kit
- Dynamic wallpaper is not available on iPhone 4.
Notes
+[AVPlayer playerWithItem:] return an AVPlayer object, but the current item will return nil if the player was created on another thread.
Store
Known Issues
App downloads can get stuck in the "Waiting" state.
Workaround: Reboot your device once or twice to resolve the issue and allow subsequent downloads to continue.
UIKit
Notes
- Before Seed 4, the snapshot API (snapshotView and resizableSnapshotViewFromRec:withCapInsets:) would defer taking the snapshot if the view had never been committed or had been addes to the view hierarchy in the current transaction. This behavior has changed. Snapshots now always represent the current, committed state of the view. Attempting to snapshot a view that never been committed logs a message and now returns nil.
- Snapshotting methods have been updated and now take an argument: afterUpdate, When set to YES, this instructs the snapshot to wait until all pending changes to the hierarchy have been committed. To maintain the pre-Seed 4 behavior, pass NO and the snapshot will capture what is currently on screen. See UIView.h for more details.
- When there isn't enough room in the navigation bar layout for the full text of the back button tittle, the navigation bar will subtitute a generic short back title (in English, "Back"). Id even that string is too long, the bar will show the back indicator chevron with no title.
- +[UIPasteboard pasteboardWithName:create:] and +[UIPasteboard pasteboardWithUniqueName] now unique the given name to allow only those apps in the same application group to access the pasteboard. If the developer attempts to create a pasteboard with a name that already exist and they are not part of the same app suite, they will get their own unique and private pasteboard. Note that this does not affect the system provided pasteboards, genereal, and find.
- Starting with Seed 2, apps default to using the new view controller-based status bar management system. To opt out of this, add a value of No for the UIViewControllerBasedStatusBarAppearance key to your info.plist.
- When using Auto Layout to position a UIButton, if you set the content compression resistance or content hugging priority to minimum, the button will have ambiguous layout. Workaroud: Don't use a content compression resistance or contetn hugging priority of less than 2 for UIButton.
- UIScreenEdgePanGestureRecognizer allows you to perform actions in response to swiper over the edge of the screen using the same heuristics that the system uses for its own gestures. Use this if you have a navigation semantic of your own that doesn't use UINavigationController but should include this gesture (e.g. Safari). This gesture recognizer has property that describes the edges on which it's active. UIRectEdge is a new enum type that this property and -[UIViewController edgesForExtendedLayout] can share. UIrectEdge replace UIExtendedEdge, which will be removed. The members of both have the same values. Use Xcode to replace all instances of "UIExtendedEdge"in project with ÜIRectEdge".
- Blurred layers are not available on iPhone 4.
- Parallax is not available on iPhone 4.
Known Issues
- Letterpress text is not available on iPhone 4.
Password fields are not displayed in alert views for apps in landscape. Text entry still works, Though you can't see what you are typing.
Weather
Notes
Weather conditions are not animated on iPhone 4.
WI-FI
Notes
Seed 4 and later includes changes to AWDL such that technologies that use it-such as AirDrop and MultiPeerConnectivity APIs-will not work properly with older seeds.
