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

- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldReceiveTouch:(UITouch *)touch{    UIView* touchedView = [touch view];    if([touchedView isKindOfClass:[UIButton class]]) {       return NO;    }    return YES;}
