使用的代码

@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");
}

试了一下 iOS：10.2,9.3 设备：iPad，iPod，iPhone 5s 在每台设备上崩溃

任何帮助将不胜感激感谢

要做的第一件事是继承UITextView并在该子类中覆盖func accessibilityActivate（） - ＆gt;布尔。然后创建一个委托来处理激活TextView时发生的事情并通过重写方法调用它。

然后根据UIAccessibilityIsVoiceOverRunning（）设置TextView的委托，因此如果正在运行语音，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覆盖的方法处理。最后，为UIAccessibilityVoiceOverStatusChanged设置一个监听器，并在从off到on时将UITextViewDelegate设置为nil，并将其设置为相反方案的原始委托类。

当用户通过语音输入时，应用程序崩溃uitextview
