Does iOS 8 support dynamic linking?

阅读更多关于 Does iOS 8 support dynamic linking?

问题 Up until iOS7, Apple did not support dynamic linking due to security concerns. Code reuse between developers usually relied on static libraries, which were built as part of the executable of the app. Introducing extensions in iOS8 seems to change this a bit, because extensions are separate executables. Sharing code between an extension and its containing app is done via a framework. Apple is saying this in their release notes: Frameworks for iOS. iOS developers can now create dynamic

iOS App Extension with xib instead of storyboard

阅读更多关于 iOS App Extension with xib instead of storyboard

问题 I'm writing an iOS 8 App Extension (widget) for the Today view. The default template in xcode comes with a storyboard. How can I use an xib file instead of an storyboard?

Today Extension height for iPad much larger than specified

阅读更多关于 Today Extension height for iPad much larger than specified

My Today extension needs to have a dynamic height based on the contents the widget is displaying. I was able to achieve this by adding a constraint on my bottom-most element: bottom layout guide's top is less than or equal to the bottom most element's bottom, with a constant of 0, priority 999, multiplier 1. This works exactly as expected on iPhones - the widget height fits all content plus the default bottom margin is applied before the next widget is shown. But on iPad it seems to be setting my widget's height equal to the max height Notification Center will allow a widget to be - there's a

阅读更多关于 Can't use keyboard extension in Spotlight after 8.3

Since I updated my keyboard extension project to Swift 1.2 and my devices to iOS 8.3, I am no longer able to use my extension in Spotlight search. My extension is not in the list if I press and hold the "globe" key, and if it's the active keyboard when entering Spotlight the system keyboard is used instead. Other 3'rd party keyboards seems to work in Spotlight - and my own keyboard works in any other app I've tried it in (Notes, Mailbox, Safari etc). It used to work in Spotlight in all iOS 8.X versions up to 8.3. Did anything change in 8.3 that I need to handle to be able to use my keyboard in

阅读更多关于 What is the purpose of widgetPerformUpdateWithCompletionHandler in iOS 8 Today Widget?

问题 Been looking around for an answer but everything seems vague or unclear. Anyways, just want to know what the purpose of the function: widgetPerformUpdateWithCompletionHandler does in the today widget. According to Apple: This method is called to give a widget an opportunity to update its contents and redraw its view prior to an operation such as a snapshot. When the widget is finished updating its contents (and redrawing, if necessary), the widget should call the completion handler block,
