UIButtons UITapGestureRecognizer后，将无法正常工作添加

Question

我有下面的代码，我添加UITapGestureRecognizer我的看法：

UITapGestureRecognizer *tap = [[UITapGestureRecognizer alloc] initWithTarget:self 
                     action:@selector(userTapped)]; 

[self.view addGestureRecognizer:tap]; 

我的问题是，当我按其它UIButton S（按钮是在IB创建）与UITapGestureRecognizer的观点相同，没有任何反应。

我想我只向gestureRecognizer添加一个动作（userTapped :)，但是如何添加与创建的其他按钮的交互？

Answer 1

尝试

tap.cancelsTouchesInView = NO; 

或

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