- (void)viewDidLoad

    [super viewDidLoad];
    
    UISwipeGestureRecognizer *leftGesture = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(swipe:)];

    UISwipeGestureRecognizer *rightGesture = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(swipe:)];
    rightGesture.direction = UISwipeGestureRecognizerDirectionUp;
    [self.tableView addGestureRecognizer:rightGesture];
}

- (void)swipe:(UISwipeGestureRecognizer *)gesture
