用户通过语音输入时，App会崩溃uitextview [英] App Crashes uitextview when user inputs via voice

问题描述

当用户在UITextView中通过语音输入文本时，应用程序崩溃

崩溃方法

使textview成为第一响应者，方法是单击它，然后按键盘上的麦克风按钮，然后讲话，然后按完成应用程序崩溃。。

在我的情况下，uitextview没什么特别的。

控制台输出

解决方案

首先要做的是对UITextView进行子类化，并在该子类中重写func accessibilityActivate（）-> Bool。然后创建一个处理TextView激活时发生的委托，并通过重写的方法对其进行调用。

然后根据UIAccessibilityIsVoiceOverRunning（）设置TextView的委托，因此如果正在运行画外音，则将UITextViewDelegate设置为nil，以防止崩溃发生，然后激活动作由您在上述子类中覆盖的方法处理。最后，为UIAccessibilityVoiceOverStatusChanged设置一个侦听器，并从关闭状态切换为打开状态时将UITextViewDelegate设置为nil，然后将其设置为相反情况下的原始委托类。

App crashes when user inputs text via voice in UITextView,

Crash Method

make textview first responder by clicking on it then Press on mic button in keyboard then speech something then press Done the app crashes..

Nothing special is done with uitextview in my case..

Console Output

tried on iOS: 10.2,9.3 device: iPad, iPod, iPhone 5s crash on every device

Any Help Would be appreciated Thanks

解决方案

The first thing to do is to subclass UITextView and in that subclass override func accessibilityActivate() -> Bool. Then make a delegate that handles what happens when the TextView is activated and call it through the overridden method.

Then set the delegate of the TextView based on UIAccessibilityIsVoiceOverRunning(), so if voice over is running then set the UITextViewDelegate to nil which prevents the crash from happening and then the activation action is handled by the method you overrode in the subclass above. Finally, set up a listener for UIAccessibilityVoiceOverStatusChanged and set the UITextViewDelegate to nil when going from off to on, and setting it to the original delegation class for the opposite scenario.
