你知道如何在安卓系统中实现相同的功能吗？ - Prabs

Answer 1

我找到了答案。 我将代码发布供您参考。 谢谢 :-)

在 viewDidLoad 中

  UISwipeGestureRecognizer *swipeGesture = [[[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(swipedScreendown:)] autorelease];
  swipeGesture.numberOfTouchesRequired = 1;
  swipeGesture.direction = UISwipeGestureRecognizerDirectionDown;
  [m_pImageView addGestureRecognizer:swipeGesture];

现在

- (void)swipedScreendown:(UISwipeGestureRecognizer*) swipeGesture {
  m_pViewController = [[ViewController alloc] initWithNibName:@"ViewController" bundle:nil];
  CATransition *transition = [CATransition animation];
  transition.duration = 0.75;
  transition.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut];
  transition.type = kCATransitionPush;
  transition.subtype = kCATransitionFromBottom;
  transition.delegate = self;
  [self.view.layer addAnimation:transition forKey:nil];
  [self.view addSubview:PadViewController.view];
}

如果您需要更多的澄清，请在这里发布。

我该如何实现上下交换？ - Raju

Answer 2

实现这个（didload）

//........towards right Gesture recogniser for swiping.....//
UISwipeGestureRecognizer *rightRecognizer = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(rightSwipeHandle:)];
rightRecognizer.direction = UISwipeGestureRecognizerDirectionRight;
[rightRecognizer setNumberOfTouchesRequired:1];
[urView addGestureRecognizer:rightRecognizer];
[rightRecognizer release];

//........towards left Gesture recogniser for swiping.....//
UISwipeGestureRecognizer *leftRecognizer = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(leftSwipeHandle:)];
leftRecognizer.direction = UISwipeGestureRecognizerDirectionLeft;
[leftRecognizer setNumberOfTouchesRequired:1];
[urView addGestureRecognizer:leftRecognizer];
[leftRecognizer release];   

然后这样：

- (void)rightSwipeHandle:(UISwipeGestureRecognizer*)gestureRecognizer 
{
//Do moving
}

- (void)leftSwipeHandle:(UISwipeGestureRecognizer*)gestureRecognizer 
{
// do moving
}

谢谢 rptwsthi。请问在“do moving”中我应该做什么？只加载一个视图控制器就可以了吗？ - Akshay

抱歉晚了，是的，你可以加载、控制器或添加子视图，但我不知道如何进行动画处理。 :I - rptwsthi

@rptwsthi 这段代码完美无缺！非常感谢你！ - cardmagik

@cardmagik为您服务。 :) - rptwsthi

这个可以工作，但导航非常快。有没有办法减慢它的速度或者让它像苹果一样（在设置中）工作？ - software is fun

为此，您可能需要使用平移手势识别器进行工作！ - rptwsthi

Answer 3

当然可以！只需将您的视图控制器设置为UIGestureRecognizerDelegate，并声明UISwipeGestureRecognizer *swipeLeftRecognizer;（还要保留和综合）。然后，在实现中，使用以下代码设置识别器：

    UIGestureRecognizer *recognizer;
    // RIGHT SWIPE
    recognizer = [[UISwipeGestureRecognizer alloc] initWithTarget:self 
                                                           action:@selector(handleSwipeFrom:)];
    [self.view addGestureRecognizer:recognizer];
    [recognizer release];
    // LEFT SWIPE
    recognizer = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(handleSwipeFrom:)];
    self.swipeLeftRecognizer = (UISwipeGestureRecognizer *)recognizer;
swipeLeftRecognizer.direction = UISwipeGestureRecognizerDirectionLeft;
    [self.view addGestureRecognizer:swipeLeftRecognizer];
self.swipeLeftRecognizer = (UISwipeGestureRecognizer *)recognizer;
    [recognizer release];

然后使用该方法触发您想要的操作。

- (void)handleSwipeFrom:(UISwipeGestureRecognizer *)recognizer {
    if (recognizer.direction == UISwipeGestureRecognizerDirectionLeft) {
        // load a different viewController
    } else {
        // load an even different viewController
    }
}

这里所做的是针对您的应用程序进行特定操作。您可以切换选项卡栏选择，通过导航控制器跳转，以模态方式呈现不同的视图，或仅执行简单的滑动过渡。

谢谢您的快速响应，PengOne。还有一个问题 - 我想让这个视图像滚动屏幕一样加载。我该怎么做？ - Akshay

动画...你可以使用简单的UIViewAnimationTransition或者做一个更加花哨的自定义动画。在谷歌上搜索一些不错的例子。 - PengOne

我知道我之前在SO上看到过一篇帖子，其中提供了获取类似于navigationControllers默认的漂亮滑动转换效果的指令，但是我现在找不到它了。我相信只要你使用几个关键词搜索就能找到它。祝你好运！ - PengOne

Answer 4

在Swift中添加手势

func addSwipes() {
    // Left Swipe
    let swipeLeft = UISwipeGestureRecognizer(target: self, action: "swipeLeft:")
    swipeLeft.direction = .Left
    self.view.addGestureRecognizer(swipeLeft)

    // Right Swipe
    let swipeRight = UISwipeGestureRecognizer(target: self, action: "swipeRight:")
    swipeRight.direction = .Right
    self.view.addGestureRecognizer(swipeRight)
}

func swipeLeft(gestureRecognizer: UISwipeGestureRecognizer) {
}

func swipeRight(gestureRecognizer: UISwipeGestureRecognizer) {

}

参考 PengOne，这是你在上面的评论中提到的代码。我保存了它在我的 Mac 上，因为我认为有一天它可能会有用... :D

// Manual navigation push animation
UIImage* image = [UIImage imageNamed:@"CurrentView"];
UIImageView* imageView = [[UIImageView alloc] initWithImage:image];
imageView.frame = self.view.bounds;
[self.view addSubview:imageView];
[imageView release];
CATransition *transition = [CATransition animation];
transition.type = kCATransitionPush;
transition.subtype = kCATransitionFromRight;
[self.view.layer addAnimation:transition forKey:@"push-transition"];
