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.)
