iOS beta 8.2 2

  iOS 8.2 beta 2 was released last evening by the Apple company, the new version of the operating system being currently available only for developers of applications for the iOS platform. Although we are talking about iOS beta 8.2 2 came three weeks away from the first version released by Apple, unfortunately we do not have as many news as we would have expected, those from Cupertino only solving operational problems, without implementing other new functions.

  Despite the lack of visible news for iOS beta 8.2 2, we still have a changelog with news provided by the Apple company in the portal dedicated to developers on its website, describing the invisible changes made by the igniters from Cupertino. Below you have the entire list of news designed by the Apple company to provide developers with the necessary information regarding the Internet changes of iOS 8.2 beta 2, so you will know exactly what's new inside it.

  iOS 8.2 beta 2 can be downloaded from the dedicated portal developers if you have an annual developer subscription.

iOS 8.2 beta 2 - here's what's new

Notes and Known Issues

The following issues relate to using iOS SDK 8.2 to develop code.

CloudKit

Footnotes

A single CKAsset instance can no longer be set as a value on multiple CKRecords.

Document Providers

Notes

  • Your app needs the iCloud entitlement to be able to be used as a document provider.

  • The com.apple.developer.icloud-container-identifiers entitlement is required.

Known Issues

  • After rotating the document picker to landscape, the status bar is hidden.

  • Upon bringing up the document picker in landscape, the containing view may be shifted beneath the navigation bar.

App extensions

Notes

  • App extensions need an arm64 slice to run on 64-bit devices. If you try to run the armv7 slice on a 64-bit device it won't work.

  • Apps need to have an arm64 slice if the bundle contains a framework that both the app and the app extension link against.

File System

Footnotes

The file system layout of app containers has changed on disk. Rather than relying on hard-coded directory structure, use theNSSearchPathForDirectoriesInDomains function or the URLForDirectory:inDomain:appropriateForURL:create:error:method of the NSFileManager class. EEA Accessing Files and Directories in File System Programming Guide.

Fonts

Footnotes

The Thai system font has increased in size to improve readability. This will cause clipping in many places in your UI if you don't take appropriate action:

  1. Use UILabel as much as possible. If you use Interface Builder, make sure that Clip Subviews is not checked. UIKit will grow the clipping region as necessary to not clip text.

  2. Use Dynamic Type. This will ensure that you do not have overlapping glyphs in multiline labels or text fields.

If you can't do 1 and 2 because you implement your own views, you must implement measures not to clip. You can use CoreText to figure out the appropriate clipping region for a line of text by calling:

CTLineGetBoundsWithOptions(lineRef, kCTLineBoundsIncludeLanguageExtents);

To avoid overlapping glyphs in multiline text elements, adjust the line height. An additional 30% is recommended.

This measure will also help your app perform better in other languages, including Arabic, Hindi, and Vietnamese.

iCloud

Footnotes

Mail handoff and AirDrop may stop working after changing your iCloud password at appleid.apple.com.

Workaround: Sign out and back into iCloud on the device.

iCloud Drive

Footnotes

URLForUbiquityContainerIdentifier: might return nil when running your application in Xcode. If so, open System Preferences, navigate to iCloud > iCloud Drive, and enable Xcode.

keyboards

Fixed in beta 2

Additional keyboards, including 3rd party keyboards, may not appear in Safari, Maps, or 3rd party apps in iOS Simulator.

Messages

Known issue

Your device may get into a state where tapping into Messages conversations can take a long time.

Workaround: Reboot the device.

Notification Center

Footnotes

The schedule and intended use of widgetPerformUpdateWithCompletionHandler: is intended as a convenient home for all data/model update logic. If implemented, the system will call at appropriate times for the widget to update its state, both when the Notification Center is visible, as well as in the background. An implementation is required to enable background updates. It's expected that the widget will perform the work to update asynchronously and off the main thread as much as possible. Widgets should call the argument block when the work is complete, passing the appropriate NCUpdateResult. Widgets should NOT block returning fromviewWillAppear: on the results of this operation. Instead, widgets should load cached state in viewWillAppear: in order to match the state of the view from the last viewWillDisappear:, then transition smoothly to the new data when it arrives.

NSURLSession

Footnotes

The NSURLSessionTask class provides a new "priority" property with three associated constants: NSURLSessionTaskPriorityDefault,NSURLSessionTaskPriorityLowand NSURLSessionTaskPriorityHigh. NSURLSessionTask priorities can be used to specify how multiple requests and responses to the same host should be prioritized. Note that the priority is a hint and not a strict guarantee ofNSURLSessionTask performance.

For complete usage details of NSURLSessionTask priorities, refer to the NSURLSession.h header file, which is provided by the Foundation framework.

Phone Number

Footnotes

To activate Wi-Fi Calling functionality for T-Mobile (US only), follow these steps:

  • Go to Settings > Phone > Wi-Fi Calling.

  • Toggle the Wi-Fi Calling switch to ON.

  • If the carrier does not have the user's registered emergency address, you will be asked to add it before the feature is activated.

Photos

Notes

  • Maintain a backup of your photo library before enabling and while using iCloud Photo Library beta by:

    • Importing to your Mac using iPhoto

    • Importing to your Mac using Image Capture

  • iCloud Photo Library beta will not download photos and videos that were synced to your device from iTunes. Any photos and videos synced to your device from iTunes will be removed when you enable iCloud Photo Library beta.

  • iPhoto for iOS will not launch on iOS 8 beta. Launching Photos.app will migrate your iPhoto edits to the iOS 8 Photo Library. Make sure your iPhoto for iOS data is included in your device backup.

  • The ability to automatically optimize device space is enabled for all accounts larger than 5GB.

  • When using iCloud Family Sharing, both iCloud Photo Sharing and My Photo Stream are enabled.

  • The WKInterfaceController method initWithContext: has been deprecated. Please use awakeWithContext: instead. The designated initializer for WKInterfaceController is Now init.

  • A page-based WatchKit app can dynamically resequence the pages at the root level usingreloadRootControllersWithNames:contexts:.

  • Rows in a WKInterfaceTable now have a default appearance. This appearance can be overridden by specifying the values ​​for background color, margin, corner radius, and height for the row in Interface Builder.

Fixed in beta 2

  • When you click Build and Run it doesn't launch the watch window.

  • The custom sash color for notification controllers does not currently appear in Interface Builder but does in iOS Simulator.

  • Installing WatchKit apps may stop working in iOS Simulator.

  • The WKInterfaceController method addMenuItemWithImage:title:action: does not work in iOS Simulator.
