如何在水平UIPageViewController中實現垂直UIPageViewController

Question

我想調整我的UIPageViewController就像在圖像中一樣工作，目前1b可以去2a等。我需要做什么來鎖定圖像中的方向？ 我忘了什么，或者我使用了錯誤的邏輯。 任何小費都會有所幫助！

請注意 ，垂直UIPageViewController位於水平UIPageViewController

水平UIPageViewController代碼

class MyPageViewController: UIPageViewController , UIPageViewControllerDataSource, UIPageViewControllerDelegate {

var pages = [UIViewController]()

override func viewDidLoad() {
    super.viewDidLoad()

    self.delegate = self
    self.dataSource = self

    let page1: UIViewController! = storyboard?.instantiateViewControllerWithIdentifier("page1")
    let page2: UIViewController! = storyboard?.instantiateViewControllerWithIdentifier("page2")
    let page3: UIViewController! = storyboard?.instantiateViewControllerWithIdentifier("page3")


    pages.append(page1)
    pages.append(page2)
    pages.append(page3)


    setViewControllers([page2], direction: UIPageViewControllerNavigationDirection.Forward, animated: false, completion: nil)
}

func pageViewController(pageViewController: UIPageViewController, viewControllerBeforeViewController viewController: UIViewController) -> UIViewController? {


    let currentIndex = pages.indexOf(viewController)!


    let previousIndex = abs((currentIndex - 1) % pages.count)


    if (previousIndex > 0)
    {
        return nil
    }



    return pages[previousIndex]
}

func pageViewController(pageViewController: UIPageViewController, viewControllerAfterViewController viewController: UIViewController) -> UIViewController? {
    let currentIndex = pages.indexOf(viewController)!
    let nextIndex = abs((currentIndex + 1) % pages.count)


    if (nextIndex < 1)

    {
        return nil
    }

    return pages[nextIndex]

}

垂直UIPageViewController代碼

class upAndDownViewController: UIPageViewController, UIPageViewControllerDataSource, UIPageViewControllerDelegate {

var pages = [UIViewController]()

override func viewDidLoad() {
    super.viewDidLoad()

    self.delegate = self
    self.dataSource = self

    let midPage: UIViewController! = storyboard?.instantiateViewControllerWithIdentifier("midPage")
    let topPage: UIViewController! = storyboard?.instantiateViewControllerWithIdentifier("topPage")



    pages.append(midPage)
    pages.append(topPage)



    setViewControllers([midPage], direction: UIPageViewControllerNavigationDirection.Forward, animated: false, completion: nil)




}

func pageViewController(pageViewController: UIPageViewController, viewControllerBeforeViewController viewController: UIViewController) -> UIViewController? {


    let currentIndex = pages.indexOf(viewController)!
    let nextIndex = abs((currentIndex + 1) % pages.count)


    if (nextIndex < 1)
    {
        return nil
    }

    return pages[nextIndex]
}

func pageViewController(pageViewController: UIPageViewController, viewControllerAfterViewController viewController: UIViewController) -> UIViewController? {

    let currentIndex = pages.indexOf(viewController)!


    let previousIndex = abs((currentIndex - 1) % pages.count)


    if (previousIndex > 0)
    {
        return nil
    }



    return pages[previousIndex]


}

我將水平UIPageViewController放在垂直的UIPageViewController 。 修復它但由於某些原因，在TOP垂直UIPageViewController內部打開的其他ViewControllers能夠向下翻頁，我會更多地了解它並可能修復它。
