UIButtons UITapGestureRecognizer後，將無法正常工作添加

Question

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

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

[self.view addGestureRecognizer:tap]; 

我的問題是，當我按其它UIButton S（按鈕是在IB創建）與UITapGestureRecognizer的觀點相同，沒有任何反應。

我想我只向gestureRecognizer添加一個動作（userTapped :)，但是如何添加與創建的其他按鈕的交互？

Answer 1

嘗試

tap.cancelsTouchesInView = NO; 

或

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