初始化带有数据的uipageviewcontroller

let pageViewController = UIPageViewController(transitionStyle: .scroll, navigationOrientation: .horizontal, options: nil)
pageViewController.dataSource = self
pageViewController.delegate = self

func pageViewController(_ pageViewController: UIPageViewController, viewControllerBefore viewController: UIViewController) -> UIViewController? {
    // 返回前一个页面的视图控制器
}

func pageViewController(_ pageViewController: UIPageViewController, viewControllerAfter viewController: UIViewController) -> UIViewController? {
    // 返回后一个页面的视图控制器
}

func presentationCount(for pageViewController: UIPageViewController) -> Int {
    // 返回页面的数量
}

func presentationIndex(for pageViewController: UIPageViewController) -> Int {
    // 返回当前页面的索引
}

func pageViewController(_ pageViewController: UIPageViewController, viewControllerBefore viewController: UIViewController) -> UIViewController? {
    // 初始化并返回前一个页面的视图控制器
}

func pageViewController(_ pageViewController: UIPageViewController, viewControllerAfter viewController: UIViewController) -> UIViewController? {
    // 初始化并返回后一个页面的视图控制器
}

func presentationCount(for pageViewController: UIPageViewController) -> Int {
    // 返回页面的数量
}

func presentationIndex(for pageViewController: UIPageViewController) -> Int {
    // 返回当前页面的索引
}

addChild(pageViewController)
view.addSubview(pageViewController.view)
pageViewController.didMove(toParent: self)
