使用滑动手势浏览视图

问题描述

| 如何使用滑动手势垂直切换视图？     

解决方法

        我找到了答案。我正在发布代码供您参考。谢谢 ：-） 在

viewDidLoad

  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];
}

如果您需要更多说明，请在此处发布。     ,        实施（下载）

//........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];   

然后这个：

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

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

    ,        当然！只需将viewController设置为

UIGestureRecognizerDelegate

，然后声明

UISwipeGestureRecognizer *swipeLeftRecognizer;

（还保留并合成）。然后，在实现中，使用

    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所需的操作

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

您在此处执行的操作特定于您的应用程序。您可以切换tabBar选择，跳过navigationController，以模态显示另一个视图，或者只是在过渡中做一个简单的幻灯片。     ,        快速添加手势

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) {

}

    ,        供参考PengOne，这是您在上面的注释中引用的代码。我将其保存在Mac上，因为我认为有一天可能会有用...：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\"];
