Ios 实现UIPageViewController'；s逻辑作为Swift中UIViewController的子视图

我必须将UIPageViewController实现为UIViewController的子视图。UIPageViewController内部有一些逻辑和其他ViewController。我的问题是如何连接下面这两段代码

这是我的主要UIViewController代码：

class MyMainViewController: UIViewController {

    override func viewDidLoad() {
       super.viewDidLoad()
    }
    override func didReceiveMemoryWarning() {
       super.didReceiveMemoryWarning()
    }   
}

还有我的UIPageViewController代码，它在他包含的ViewController之间实现了一个无休止的循环（我复制了整个代码，可能没有必要）：

在布局

MyMainViewController

和

TutorialPageViewController

的情节提要中，需要将容器视图添加到

MyMainViewController

，然后使用

Embed

分段嵌入

TutorialPageViewController

当显示

MyMainViewController

时，它现在也会自动插入教程视图

class TutorialPageViewController: UIPageViewController {

    private(set) lazy var orderedViewControllers: [UIViewController] = {
        return [self.newColoredViewController("Green"),
                self.newColoredViewController("Red"),
                self.newColoredViewController("Blue")]
    }()

    override func viewDidLoad() {
        super.viewDidLoad()

        dataSource = self

        if let firstViewController = orderedViewControllers.first {
            setViewControllers([firstViewController],
                direction: .Forward,
                animated: true,
                completion: nil)
        }
    }

    private func newColoredViewController(color: String) -> UIViewController {
        return UIStoryboard(name: "Main", bundle: nil) .
        instantiateViewControllerWithIdentifier("\(color)ViewController")
    }

}

extension TutorialPageViewController: UIPageViewControllerDataSource {

    func pageViewController(pageViewController: UIPageViewController, viewControllerBeforeViewController viewController: UIViewController) -> UIViewController? {
        guard let viewControllerIndex = orderedViewControllers.indexOf(viewController) else {
            return nil
        }

        let previousIndex = viewControllerIndex - 1
        guard previousIndex >= 0 else {
            return orderedViewControllers.last
        }
        guard orderedViewControllers.count > previousIndex else {
            return nil
        }
        return orderedViewControllers[previousIndex]
    }

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

        guard let viewControllerIndex = orderedViewControllers.indexOf(viewController) else {
            return nil
        }

        let nextIndex = viewControllerIndex + 1
        let orderedViewControllersCount = orderedViewControllers.count

        guard orderedViewControllersCount != nextIndex else {
            return orderedViewControllers.first
        }

        guard orderedViewControllersCount > nextIndex else {
            return nil
        }

        return orderedViewControllers[nextIndex]
    }

    func presentationCountForPageViewController(pageViewController: UIPageViewController) -> Int {
        return orderedViewControllers.count
    }

    func presentationIndexForPageViewController(pageViewController: UIPageViewController) -> Int {
        guard let firstViewController = viewControllers?.first,
        firstViewControllerIndex = orderedViewControllers.indexOf(firstViewController) else {
            return 0
        }

        return firstViewControllerIndex
    }

}
