Objective c 当点击文本视图成为第一响应者后，如何识别它？

当点击UITextView时，我希望它继续作为第一响应程序工作，但我还需要触发其他事件。UITapGestureRecognitor在UITextView不是第一响应者之前工作良好，但在其聚焦后，tap不再被识别

  UITapGestureRecognizer *singleTap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(singleTapRecognized:)];
  singleTap.numberOfTapsRequired = 1;
  [txtView addGestureRecognizer:singleTap];
  [singleTap release];

  -(IBAction)singleTapRecognized:(id)sender
  {
     //Does not enter here with a tap after txtView is first responder
  }

在

ViewDidLoad（）

方法中使用以下代码，并确保包括

[yourTextView setUserInteractionEnabled:YES] 

UITapGestureRecognizer *gestureRecognizer = [[UITapGestureRecognizer alloc]initWithTarget:self action:SEL(textViewTapped:)];

 [gestureRecognizer setNumberOfTapsRequired:1];  
 [yourTextView addGestureRecognizer:gestureRecognizer];`

---

应在手势识别器代理上实现以下方法：

-(BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldRecognizeSimultaneouslyWithGestureRecognizer:(UIGestureRecognizer*)otherGestureRecognizer {
    return YES;  
}

---

在我的代码中创建手势识别器是在viewdidload中完成的。我看不出我的代码和这个代码有什么区别。我还试着将交互设置为启用状态，但没有任何区别。我认为UITextView的交互启用默认情况下是正确的。您找到过解决方案吗？
