的第一件事要做的iPad，iPod，iPhone手机5S 崩溃是继承的UITextView并在该子类中重写func accessibilityActivate（） - > Bool。然后创建一个委托来处理TextView被激活时发生的情况，并通过重写的方法调用它。

然后根据UIAccessibilityIsVoiceOverRunning（）设置TextView的委托，因此如果voice over正在运行，则将UITextViewDelegate设置为nil，以防止发生崩溃，然后通过您在子类中覆盖的方法处理激活操作以上。最后，为UIAccessibilityVoiceOverStatusChanged设置一个侦听器，并将UITextViewDelegate设置为从关闭到打开为止，并将其设置为相反方案的原始代理类。
