iOS Today Extension 中奇怪的 NSInternalInconsistencyException 和 PKService 崩溃
Strange NSInternalInconsistencyException and PKService crash in iOS Today Extension
我在我的 iOS Today Extension 上安装了 Crashlytics，但我遇到了这个奇怪的崩溃。有谁知道为什么会这样？
Fatal Exception: NSInternalInconsistencyException
removing inactive plug-in com.somecompany.someapp.TodayExtension(1.0)>
崩溃的行是
11 PlugInKit -[PKService unregisterPersonality:] + 188
在我今天的扩展中，在 viewDidLoad 中，它将获取用户的当前位置，然后发出网络请求以获取有关该位置的数据。发生这种情况是因为我的操作花费的时间太长并且 iOS 正在终止我的扩展吗？我无法重现这一点，但我认为用户看到的是一个空白 space 扩展名应该在的地方，或者除了扩展名的标题外什么都没有显示。

我在 Crashlytics 上看到了完全相同的东西。
根据 Apple 的说法，此崩溃是 iOS 8（包括 8.3 beta）中的一个已知错误。崩溃仅在扩展程序关闭时发生，这意味着用户不会看到扩展程序崩溃。
所以我们现在唯一能做的就是忽略这次崩溃
