ios - Swift pagecontroller Storyboard UI 对象与 UIPageviewcontroller 连接

Question

我已经在容器 View 中完成了 pageviewcontroller 我可以使用编程方式显示页面控制，但我的容器 View 是使用 Storyboard完成的，所以我不知道如何在容器中心内显示页面 Controller 。因此，我使用 Storyboard页面 Controller ui 对象拖放它，现在如何连接我的页面 View Controller 方法以及如何通过使用 pageviewcontroller 图像数组计数使点移动。

func configurePageControl() {
        // The total number of pages that are available is based on how many available colors we have.
        //pageControl = UIPageControl(frame: CGRect(x: 0,y: UIScreen.main.bounds.maxY - 50,width: UIScreen.main.bounds.width,height: 50))
        pageControl = UIPageControl(frame: CGRect(x: self.containerview.frame.size.width / 2, y: self.containerview.frame.size.height - 50,width: UIScreen.main.bounds.width,height: 50))

        self.pageControl.numberOfPages = pageTitles.count
        self.pageControl.currentPage = 0
        self.pageControl.tintColor = UIColor.black
        self.pageControl.pageIndicatorTintColor = UIColor.white
        self.pageControl.currentPageIndicatorTintColor = UIColor.black
        //self.containerview.addSubview(pageControl)
    }

    // MARK: Delegate functions
    func pageViewController(_ pageViewController: UIPageViewController, didFinishAnimating finished: Bool, previousViewControllers: [UIViewController], transitionCompleted completed: Bool) {
        let pageContentViewController = pageViewController.viewControllers![0]
        //self.pageControl.currentPage = pageTitles.index(of: pageContentViewController)!
    }

Answer 1

func pageViewController(_ pageViewController: UIPageViewController, didFinishAnimating finished: Bool, previousViewControllers: [UIViewController], transitionCompleted completed: Bool) {

if let viewController = pageViewController.viewControllers?[0] {
    guard let index = arrayVCs.index(of: viewController) else {
        return
    }
    //you can find index here..
    self.pageControl.currentPage = index
}
}

更新

    func pageViewController(pageViewController: UIPageViewController, didFinishAnimating finished: Bool, previousViewControllers: [UIViewController], transitionCompleted completed: Bool)
{
    if (!completed) {
        self.pageControl.currentPage = pageViewController.viewControllers!.first!.view.tag //

    }
}

Set tags to your viewcontrollers view.
