在键盘可见时，iOS按钮点击不会触发？

Question

我有一个很奇怪的问题，里面有UITableView和UIButtons。

我的表格包含3个部分，每个部分有1个原型单元格。最后一个类型包含4个按钮（其中2个触发连接到Web服务的过程，并触发segue进入下一页）。我也有UITextField第一类UITableViewCell。

我的逻辑工作正常，除了一种情况 - 当我在里面编辑和我的键盘是可见的 - 我滚动（不退出编辑模式）。当我按下两个按钮中的一个时，我只能退出编辑模式 - 按钮的轻击不会被触发。

任何想法，可能是原因？

我拦截Gesture Recognizer，但视图的标记是0--无论我将它设置为-1300。我使用的代码：

UIView *view = gestRecognzr.view; 
NSLog(@"%d", view.tag);//By tag, you can find out where you had tapped. 

我说明键盘使用的通知和下面的代码：

// Add code for keyboard management 
[[NSNotificationCenter defaultCenter] addObserver:self 
             selector:@selector(keyboardShow:) 
              name:UIKeyboardWillShowNotification 
              object:nil]; 
[[NSNotificationCenter defaultCenter] addObserver:self 
             selector:@selector(keyboardHide:) 
              name:UIKeyboardWillHideNotification 
              object:nil];

您需要实现UIGestureRecognizerDelegate和bypa如果视图是你的按钮，那么ss gesturerecognizer动作。

- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldReceiveTouch:(UITouch *)touch { 
    return (touch.view != yourButton); 
}
