如何在iphone sdk中更改滑动时的视图控制器？

我想通过像我一样滑动控制器来更改视图控制器，当我滑动时，消息框应该从ViewController1->ViewController2和ViewController1滑动谢谢。我知道这一点，但这将改变视图控制器，就像改变iphone中的页面一样。你到底想做什么？请下载mobli应用程序，并通过滑动Feed->Me->Popular->等检查他们是否正在改变视图控制器。。。我想做一些类似的事情，但我想通过滑动来更改iPhone Message->Email MessageController的视图。你需要什么样的滑动？就像换页一样，只需轻扫和轻扫。然后打开emailcomposer或messagecomposer，就像你可以在iPad中通过滑动找到的那样。当应用程序打开超过2次时，4个手指在屏幕上

- (void)goToNext{
    //your code to load youn next view controller
}

- (void)goToBack{
    //your code to load your previous view controller
}

- (void)viewDidLoad{
    [super viewDidLoad];

    UISwipeGestureRecognizer *recognizer;

    recognizer = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(goToNext)];
    [recognizer setDirection:(UISwipeGestureRecognizerDirectionRight)];
    [[self view] addGestureRecognizer:recognizer];
    [recognizer release];

    recognizer = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(goToBack)];
    [recognizer setDirection:(UISwipeGestureRecognizerDirectionUp)];
    [[self view] addGestureRecognizer:recognizer];
    [recognizer release];
}
