How can I detect from an iOS Keyboard Extension if the keyboard is interrupted, for example an incoming phone call.如果键盘中断，例如来电，我如何从 iOS 键盘扩展中检测到。

I have added observers for applicationWillResignActive and applicationDidBecomeActive in UIInputViewController's viewDidLoad .我在 UIInputViewController 的viewDidLoad为applicationWillResignActive和applicationDidBecomeActive添加了观察者。 I have also added logging in those, plus logging in viewWillAppear and viewWillDisappear .我还添加了这些日志，以及viewWillAppear和viewWillDisappear日志。

When I get an incoming phone call with my keyboard displayed -- I do not reliably get applicationWillResignActive , nor do I reliably get viewWillDisappear .当我在显示键盘的情况下接到来电时 - 我不能可靠地获得applicationWillResignActive ，也不能可靠地获得viewWillDisappear 。

I set Xcode "logging" breakpoints on the observers willResignActive and didBecomeActive to log the name of the breakpoint.我在观察者willResignActive和didBecomeActive上设置了 Xcode“记录”断点以记录断点的名称。 Xcode logged willResignActive every time my phone received a call and didBecomeActive every time the call ended.每次我的手机接到电话时，Xcode 都会记录willResignActive每次电话结束时都会记录didBecomeActive 。 I am realizing that calls to NSLog and "watching for them" in the Console App on my Mac may not be the correct approach.我意识到在我的 Mac 上的控制台应用程序中调用 NSLog 和“监视它们”可能不是正确的方法。 NSLog/Console seems flaky: ie, drops NSLog messages. NSLog/Console 似乎不稳定：即，丢弃 NSLog 消息。
