左右手势的滑动，来切换页面

    //向左滑动的时候的手势

    UISwipeGestureRecognizer *leftSwipeGestureRecognizer = [[UISwipeGestureRecognizer alloc]initWithTarget:self action:@selector(presentRightMenuViewController:)];

    [leftSwipeGestureRecognizer setDirection:UISwipeGestureRecognizerDirectionLeft];

    [self.view addGestureRecognizer:leftSwipeGestureRecognizer ];

    //向右滑动时候的手势

    UISwipeGestureRecognizer *rithSwipeGestureRecognizer = [[UISwipeGestureRecognizer alloc]initWithTarget:self action:@selector(presentRightMenuViewController:)];

    [rithSwipeGestureRecognizer setDirection:UISwipeGestureRecognizerDirectionRight];

    [self.view addGestureRecognizer:rithSwipeGestureRecognizer ];

- (void)presentRightMenuViewController:(UISwipeGestureRecognizer *)dddd

{

    [self.navigationController popViewControllerAnimated:YES];

}

那么问题来咯，现在返回上一个页面后，会崩溃，错误原因，  -------待结果
