iOS uitableView响应事件被拦截

   

     //加入手势，点击屏幕其它区域关闭键盘操作
        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;
}
