在已经响应UITapGestureRecognizer的UIView中清晰的响应UIButton点击事件

今天码代码。。发现我自己在UIScrollView的UIButton老是不响应，开始以为是委托的问题，后来找了半天发现是我已经响应了UITapGestureRecognizer

UITapGestureRecognizer *singleTap = [[UITapGestureRecognizer alloc] initWithTarget:self
action:@selector(tapButton:)];
[cba addGestureRecognizer:singleTap];
[singleTap release];

如果要清晰响应UIButton那就需要下面这段代码：

- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldReceiveTouch:(UITouch *)touch
{
UIView* touchedView = [touch view];
if([touchedView isKindOfClass:[UIButton class]]) {

return NO;
}

return YES;
}
