左右手勢的滑動，來切換頁面

    //向左滑動的時候的手勢

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

    [leftSwipeGestureRecognizer setDirection:UISwipeGestureRecognizerDirectionLeft];

    [self.view addGestureRecognizer:leftSwipeGestureRecognizer ];

    //向右滑動時候的手勢

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

    [rithSwipeGestureRecognizer setDirection:UISwipeGestureRecognizerDirectionRight];

    [self.view addGestureRecognizer:rithSwipeGestureRecognizer ];

- (void)presentRightMenuViewController:(UISwipeGestureRecognizer *)dddd

{

    [self.navigationController popViewControllerAnimated:YES];

}

那么問題來咯，現在返回上一個頁面后，會崩潰，錯誤原因，  -------待結果
