iOS uitableView响应事件被拦截

   

     //添加手势，点击屏幕其他区域关闭键盘操作        UITapGestureRecognizer *gesture = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(SEL)];        gesture.numberOfTapsRequired = 1;        gesture.delegate = self;        [self.view addGestureRecognizer:gesture];

#pragma mark - UIGestureRecognizerDelegate- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldReceiveTouch:(UITouch *)touch{    // 若为UITableViewCellContentView（即点击了tableViewCell），则不截获Touch事件    if ([NSStringFromClass([touch.view class]) isEqualToString:@"UITableViewCellContentView"]) {        return NO;    }    return  YES;}
