Ios 当用户通过语音输入时，应用程序崩溃uitextview

当用户在UITextView中通过语音输入文本时，应用程序崩溃

碰撞方法

点击文本视图，然后按键盘上的麦克风按钮，然后讲话，然后按完成，使该应用程序崩溃。

在我的情况下，uitextview没有做任何特殊的处理

控制台输出

}

在每个设备上崩溃

任何帮助都将不胜感激
谢谢
首先要做的是将UITextView子类化，并在该子类中覆盖func accessibilityActivate（）->Bool。然后创建一个委托，处理激活TextView时发生的事情，并通过重写方法调用它

然后根据UIAccessibilityVoiceOverwring（）设置TextView的委托，因此如果正在运行voice Overwring（），则将UITextViewDelegate设置为nil，以防止崩溃发生，然后激活操作由您在上面的子类中重写的方法处理。最后，s
@property(strong,nonatomic) UITextView *addressTextView;
- (void)viewDidLoad {
    [super viewDidLoad];
    addressTextView.delegate = self;
    addressTextView.text = [self.dictionaryEditObject objectForKey:@"location"];
}
-(void)textViewDidBeginEditing:(UITextView *)textView
{

}
- (BOOL)textViewShouldBeginEditing:(UITextView *)textView
{
    NSLog(@"textViewShouldBeginEditing:");

    return YES;
}

-(void)textViewDidEndEditing:(UITextView *)textView
{
    NSLog(@"textViewDidEndEditing");
}
