ios如何使UITextView检测一下？

- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event{
    NSLog(@"touchesBegan");
 
    //test
    UITouch *touch = [event allTouches] anyObject];
    if ([touch tapCount] == 2) {
        NSLog (@"tapcount 2");
        [self.textview becomeFirstResponder];
 
    }   
 
     else if ([touch tapCount] == 1) {
         NSLog (@"tapcount 1");
         [self.textview becomeFirstResponder];
         [self.view performSelector:@selector(select:)];
 
 
     }
 
}
 
- (void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event{
    [super touchesBegan:touches withEvent:event];
    NSLog(@"touchesMoved");
}
 
- (void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event{
    NSLog(@"****touchesEnded");
    [self.nextResponder touchesEnded: touches withEvent:event]; 
    NSLog(@"****touchesEnded");
    [super touchesEnded:touches withEvent:event];
    NSLog(@"****touchesEnded");
}
 
- (void)touchesCancelled:(NSSet *)touches withEvent:(UIEvent *)event{
    [super touchesCancelled:touches withEvent:event]; 
    NSLog(@"touchesCancelled");
}

我的问题：

我想在UITextView上点击一次即可模拟两个水龙头,这是该代码中的textview.但是当我在textview上点击一次或两次时,我只能从一个和两个水龙头得到NSLog,只有在外面.我应该怎么做才能使它工作？

解决方法

可能我会在这里使用两个 gesture recognizers.

//...some stuff above here probably in you're controllers viewDidLoad
 
UITapGestureRecognizer *singleTap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(singleTapRecognized:)];
singleTap.numberOfTapsrequired = 1;
[someTextView addGestureRecognizer:singleTap];
[singleTap release];
 
UITapGestureRecognizer *doubleTap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(doubleTapRecognized:)];
doubleTap.numberOfTapsrequired = 2;
[someTextView addGestureRecognizer:doubleTap];
[doubleTap release];

选择器就像：

- (void)singleTapRecognized:(UIGestureRecognizer *)gestureRecognizer {
    NSLog(@"single tap");
    // ...etc
}
 
- (void)doubleTapRecognized:(UIGestureRecognizer *)gestureRecognizer {
    NSLog(@"double tap");
    // ...etc
}
