Patch release to fix a bug affecting tag migration for tags set through UAPush. This only affects devices that migrate to SDK 12.0.x-12.1.1. This patch release fixes the bug by combining previous tags with tags that have been set since the update to 12.x. Applications using 12.0.x-12.1.1 should update.

Custom channel attributes are currently a beta feature. If you wish to participate in the beta program, please complete our signup form.

As of SDK 13 static libraries will be removed from the binary distribution. Apps currently using these should begin migrating to the new xcframeworks replacing them.

Changes

• Added a new UAAttributeMutations class
• Added a new applyAttributeMutations method to UAChannel

Version 12.0.2 - November 5, 2019

Patch release to fix stability issues with in-app automation. Applications using in-app automation should update.

Note for apps that directly schedule In-App Messages using the SDK

Some apps may be using the UAInAppMessageManager's scheduleMessageWithScheduleInfo or scheduleMessagesWithScheduleInfo methods to directly schedule In-App messages through the SDK. The first time the app runs with this version of the SDK, any In-App Messages that were directly scheduled by the app will be canceled and removed. The app will need to re-schedule those messages.

Apps whose in-app messages are scheduled only through the Airship message composers (go.urbanairship.com) don't need to take any additional action after upgrading to this version.

6.2.2 - September 17, 2015

• Disabled modules in the static library to resolve Xcode 7 module cache warnings. Note: While this change should be backwards compatible with most existing apps, Swift apps built against the static library will need to explicitly link against CoreTelephony.framework when building with Xcode 6.4.

6.2.1 - September 14, 2015

• Added a separate build compiled with Xcode 7 for bitcode support.
• Updated UAirship, UAPush, UAInbox, and UAUser nullability attribute to be null_unspecified instead of nullable.

It is strongly recommended to link the Settings app instead of providing an in-app toggle to turn on and off push. This is to work around ongoing bugs in iOS8 (Radar #17878212).
• Modernized public BOOL properties to include the prefix "is" on the getter.
• Reduced the number of internal singletons. UAPush, UAInbox, UAUser, UAActionRegistry shared methods have been deprecated and are now accessible from class methods on UAirship.

New Features

• Full support for iOS 8, including compatibility with Swift applications.
• Includes an Embedded.framework for use in applications with a minimum SDK version of 8.0.
• Includes support for interactive notifications and the new iOS 8 notification registration model.
  • Includes more than 25 built-in interactive notification sets, including button resources for 9 languages.
  • Additional/replacement localization strings may be added to built-in actions.
• Includes a new action for social sharing that can be called from pushes or web views.
• Includes support for defining custom events in our reporting system.
• Background push can now be used without an opt-in prompt (request remote-notification background type in your Info.plist).
• The inbox now stores local state for read/delete. The UI no longer needs to block while updates are made.
• Inbox core data operations are now performed on a background queue.

Major API Changes

• User notifications (badge, alert, sound) now default to OFF. This change is designed to make it easier to prompt for permission in the right spot. If you were relying on the old default (push enabled at start), you will need to update your registration logic.
• Supports iOS 6+. (Support for iOS 5 has been removed).
• UA location now handles iOS8-style authorization. Once location reporting is started and an authorization prompt is presented, changes to the authorization level are not possible without updating the app in the App Store. By default, "always" authorization will be requested. To request "when in use" set the property 'requestAlwaysAuthorization' to NO on UALocationService.
• Replaced existing tag modifiers on UAPush with more concisely named methods: addTag, addTags, removeTag, and removeTags.
• FOR DETAILED INFO: http://docs.urbanairship.com/topic_guides/ios_migration.html

Sample UI Changes

• Removed UAInboxUI and UAPushUI protocols. Sample code now displays views directly.
• Refactored the localization in both sample projects.
• Moved sample resources to a new common folder (including those used in the interactive notifications).
• Sample projects now include targets that use the embedded framework (static library still used in the original targets).

General Modernization

• Modernized init and factory methods. All now return instancetype rather than id or concrete classes.
• NS_ENUM and NS_OPTIONS are now used throughout.
• Removed previously deprecated methods and classes.
• Removed use of methods deprecated in iOS 6 (now that iOS 5 support has been dropped).

Documentation Updates

• The SDK distribution now includes the API reference documentation in the reference-docs folder.
• The generated (header) documentation (in reference-docs) now has complete coverage of our public interface, including enums and block types.

4.0.4 - September 10, 2014

• Fixed iOS 8 push prompt on first-run and immediate opt-out.
• Fixed quiet time setting not persisting between application restarts.
• Added work around for iOS 8 registration bug where disabling push registering prevents registering for notification types without a device restart. Instead of registering for 0 notification types, the device will just be marked as opted-out. This only affects newer iOS 8 devices. For more information, see the documentation for allowUnregisteringUserNotificationTypes on UAPush.
• UA location is now compatible with iOS 8 authorization modes. If building against Xcode 6, make sure to add the new authorization keys (NSLocationAlwaysUsageDescription and NSLocationWhenInUseUsageDescription) to the application's info.plist. You must also manually request the correct authorization before starting location on Urban Airship by calling either requestWhenInUseAuthorization or requestAlwaysAuthorization on CLLocationManager.

4.0.3 - August 28, 2014

• Use background tasks for all registration and analytics traffic.
• Refactored Urban Airship JavaScript interface injection and webview url interception into UAWebViewTools and UIWebView+UAAdditions.
• Deprecated Urban Airship scheme "ua" in favor of the new scheme "uairship".

• New AirshipConfig.plist format. The new key names match the property names on UAConfig, though the old keys are still valid.
• Added an auto-integration feature. By default, it is no longer necessary to add remote notification callbacks to your app delegate or explicitly register for push. This can be configured with a UAConfig option.
• The UA app key can now be automatically toggled between development and production based on the status of an app as indicated in the embedded .mobileprovision file.
• Push conversion events are now automatically collected - no integration required.
