关于点击键盘，手势会穿透键盘，点击到键盘底下的Cell，这是什么原因？

当键盘显示或消失时，系统会发送相关的通知:

 UIKeyboardWillShowNotification
 UIKeyboardDidShowNotification
 UIKeyboardWillHideNotification
 UIKeyboardDidHideNotification

截取通知

 [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(keyboardWillShow:) name:UIKeyboardWillShowNotification object:nil];
(void)keyboardWillShow:(NSNotification *)noti {
 //键盘输入的界面调整
 //键盘的高度 float height = 216.0;
 CGRect frame = self.view.frame;
 frame.size = CGSizeMake(frame.size.width, frame.size.height - height);
 [UIView beginAnimations:@"Curl"context:nil];//动画开始
 [UIView setAnimationDuration:0.30];
 [UIView setAnimationDelegate:self];
 [self.view setFrame:frame];
 [UIView commitAnimations]; }

大概就是这么个思路
