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
}
