我将singTap和doubleTap添加到如下代码的视图中：
- -(void)awakeFromNib{
- [self setUserInteractionEnabled:YES];
- //
- UITapGestureRecognizer *doubleTapGesture = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(handleDoubleTapGesture:)];
- doubleTapGesture.numberOfTapsrequired = 2;
- [self addGestureRecognizer:doubleTapGesture];
- UITapGestureRecognizer *singleTapGesture = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(handleSingleTapGesture:)];
- singleTapGesture.numberOfTapsrequired = 1;
- [self addGestureRecognizer:singleTapGesture];
- }
- -(void)handleSingleTapGesture:(UITapGestureRecognizer *)singleTapGesture{
- [[self delegate] singleTapOnView];
- }
- -(void)handleDoubleTapGesture:(UITapGestureRecognizer *)doubleTapGesture{
- [[self delegate] doubleTapOnView];
- }
当doubleTap时,singleTap也会开火.如何在doubleTap时禁用singleTap？谢谢！
解决方法
告诉单击识别器它需要双击识别器在触发之前失败：
- [singleTapGesture requireGestureRecognizerToFail:doubleTapGesture];
(这实际上是UIGestureRecognizer docs for this method中的典型示例.)
