ios – 禁用UIPageViewController弹跳

参见英文答案 > Disable UIPageViewController bounce8个
我一直在制作一个在UIViewControllers之间滚动的示例应用程序,但重点是我想在滚动结束时和返回第一个UIViewController时禁用弹跳效果.

这是我的代码：

class PageViewController: UIPageViewController,UIPageViewControllerDataSource,UIPageViewControllerDelegate{
 
    var index = 0
    var identifiers: NSArray = ["FirstNavigationController","SecondNavigationController"]
    override func viewDidLoad() {
 
        self.dataSource = self
        self.delegate = self
 
        let startingViewController = self.viewControllerAtIndex(self.index)
 
        let viewControllers: NSArray = [startingViewController]
        self.setViewControllers(viewControllers as [AnyObject],direction: UIPageViewControllerNavigationDirection.Forward,animated: false,completion: nil)
    }
 
    func viewControllerAtIndex(index: Int) -> UINavigationController! {
 
        let storyBoard : UIStoryboard = UIStoryboard(name: "Main",bundle:nil)
        //first view controller = firstViewControllers navigation controller
        if index == 0 {
 
            return storyBoard.instantiateViewControllerWithIdentifier("FirstNavigationController") as! UINavigationController
 
        }
 
        //second view controller = secondViewController's navigation controller
        if index == 1 {
 
            return storyBoard.instantiateViewControllerWithIdentifier("SecondNavigationController") as! UINavigationController
        }
 
        return nil
    }
    func pageViewController(pageViewController: UIPageViewController,viewControllerAfterViewController viewController: UIViewController) -> UIViewController? {
 
        let identifier = viewController.restorationIdentifier
        let index = self.identifiers.indexOfObject(identifier!)
 
        //if the index is the end of the array,return nil since we dont want a view controller after the last one
        if index == identifiers.count - 1 {
 
            return nil
        }
 
        //increment the index to get the viewController after the current index
        self.index = self.index + 1
        return self.viewControllerAtIndex(self.index)
 
    }
 
    func pageViewController(pageViewController: UIPageViewController,viewControllerBeforeViewController viewController: UIViewController) -> UIViewController? {
 
        let identifier = viewController.restorationIdentifier
        let index = self.identifiers.indexOfObject(identifier!)
 
        //if the index is 0,return nil since we dont want a view controller before the first one
        if index == 0 {
 
            return nil
        }
 
        //decrement the index to get the viewController before the current one
        self.index = self.index - 1
        return self.viewControllerAtIndex(self.index)
 
    }
 
}

解决方法

我不知道你能不能. UIPageController不是很容易定制的.

就个人而言,当我想在UIViewController之间滚动时,我更喜欢使用一个简单的UIViewController,它将是一个容器,里面有一个UIScrollView.然后我以编程方式添加UIScrollView的contentSize中的所有控制器.您必须将所有控制器添加为容器的子级.

更新iOS 9

func setupDetailViewControllers() {
    var prevIoUsController: UIViewController?
    for controller in self.controllers {
        addChildViewController(controller)
        addControllerInContentView(controller,prevIoUsController: prevIoUsController)
        controller.didMoveToParentViewController(self)
        prevIoUsController = controller
    }
}
 
func addControllerInContentView(controller: UIViewController,prevIoUsController: UIViewController?) {
    contentView.addSubview(controller.view)
    controller.view.translatesAutoresizingMaskIntoConstraints = false
 
    // top
    controller.view.topAnchor.constraintEqualToAnchor(contentView.topAnchor).active = true
 
    // bottom
    controller.view.bottomAnchor.constraintEqualToAnchor(contentView.bottomAnchor).active = true
 
    // trailing
    trailingContentViewConstraint?.active = false
    trailingContentViewConstraint = controller.view.trailingAnchor.constraintEqualToAnchor(contentView.trailingAnchor)
    trailingContentViewConstraint?.active = true
 
    // leading
    let leadingAnchor = prevIoUsController?.view.trailingAnchor ?? contentView.leadingAnchor
    controller.view.leadingAnchor.constraintEqualToAnchor(leadingAnchor).active = true
 
    // width
    controller.view.widthAnchor.constraintEqualToAnchor(scrollView.widthAnchor).active = true
}

以前的答案

像这样：

scrollView是一个IBOutlet,与ContainerViewController的每个边缘都有约束

class ContainerViewController: UIViewController {
 
@IBOutlet var scrollView: UIScrollView!
 
override func viewDidLoad() {
    super.viewDidLoad()
    scrollView.bounces = false
    scrollView.pagingEnabled = true
}
 
override func didReceiveMemoryWarning() {
    super.didReceiveMemoryWarning()
 
}
 
override func viewDidLayoutSubviews() {
    initScrollView()
}
 
func initScrollView(){
    let viewController1 = storyboard?.instantiateViewControllerWithIdentifier("ViewController1") as! ViewController1
 
    viewController1.willMoveToParentViewController(self)
    viewController1.view.frame = scrollView.bounds
 
    let viewController2 = storyboard?.instantiateViewControllerWithIdentifier("ViewController2") as! ViewController2
 
    viewController2.willMoveToParentViewController(self)
    viewController2.view.frame.size = scrollView.frame.size
    viewController2.view.frame.origin = CGPoint(x: view.frame.width,y: 0)
 
    scrollView.contentSize = CGSize(width: 2 * scrollView.frame.width,height: scrollView.frame.height)
 
    scrollView.addSubview(viewController2.view)
    self.addChildViewController(viewController2)
    viewController2.didMoveToParentViewController(self)
 
    scrollView.addSubview(viewController1.view)
    self.addChildViewController(viewController1)
    viewController1.didMoveToParentViewController(self)
}}
