如何将一个UIViewController作为屏幕的一部分

我需要有一个UIPageViewController在屏幕顶部对我的图像进行幻灯片显示...我认为很好的例子是Airbnb应用程序，当您选择房屋时，您将被推向顶部查看包含图像阵列的控制器在PageViewController中（我认为）

我不得不说我有一个由collectionView驱动的应用程序，我希望它位于我的顶级UICollectionViewCell上。

我也发现了一些关于使用容器的东西，但我不知道如何添加...

还有一些我不使用StoryBoard ...

import UIKit

class ImageCell: UICollectionViewCell {
    override init(frame: CGRect) {
        super.init(frame: frame)
        setupView()    }

    required init?(coder aDecoder: NSCoder) {
        fatalError("init(coder:) has not been implemented")
    }

    let imageView : UIImageView = {
        let image = UIImageView()
        image.image = #imageLiteral(resourceName: "Apple_Watch_Main")
        image.translatesAutoresizingMaskIntoConstraints = false
        return image
    }()

    func setupView() {
        backgroundColor = .black
        addSubview(imageView)
        addConstraints(NSLayoutConstraint.constraints(withVisualFormat: "H:|[v0]|", options: NSLayoutFormatOptions(), metrics: nil, views: ["v0" : imageView]))

        addConstraints(NSLayoutConstraint.constraints(withVisualFormat: "V:|[v0]|", options: NSLayoutFormatOptions(), metrics: nil, views: ["v0" : imageView]))
    }
}

这是我要添加该UIPageViewController的单元格

我找到了答案

我做了这样的小考

class PageViewController: UIPageViewController , UIPageViewControllerDataSource{
    override func viewDidLoad() {
        super.viewDidLoad()

        dataSource = self
        let frameViewController = FrameViewController()
        frameViewController.imageName = imageNames.first

        let viewControllers = [frameViewController]
        setViewControllers(viewControllers, direction: .forward, animated: true, completion: nil)
    }

    let imageNames = ["Apple_Watch_Main" , "Pic2" , "Pic3"]

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

        let currentImageName = (viewController as! FrameViewController).imageName
        let currentIndex = imageNames.index(of: currentImageName!)
        if currentIndex! > 0 {
            let frameViewController = FrameViewController()
            frameViewController.imageName = imageNames[currentIndex! - 1]
            return frameViewController
        }
        return nil
    }

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

        let currentImageName = (viewController as! FrameViewController).imageName
        let currentIndex = imageNames.index(of: currentImageName!)
        if currentIndex! < imageNames.count - 1 {
            let frameViewController = FrameViewController()
            frameViewController.imageName = imageNames[currentIndex! + 1]
            return frameViewController
        }
        return nil
    }
}

在我的视图集合中，我将第一个单元格完全清空，因此就像一个窗口，然后向该单元格添加了子视图控制器和页面控制器的视图，现在效果很好

这是代码

override func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {

        switch indexPath.item {
        case 0 :
            let cell = collectionView.dequeueReusableCell(withReuseIdentifier: cellId, for: indexPath) as!ImageCell

            let pagecontroller = PageViewController(transitionStyle: .scroll, navigationOrientation: .horizontal, options: nil)
            self.addChildViewController(pagecontroller)

            cell.addSubview(pagecontroller.view)

            pagecontroller.view.frame = CGRect(x: 0, y: 0, width: view.frame.width, height: view.frame.height/3)
            return cell
        case 1 :
            let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "filterandorganize", for: indexPath) as! FilterAndOrganize
            return cell
        case 2 :
            let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "Offers", for: indexPath) as! Offers
            return cell
        case 3 :
            let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "OfferedProducts", for: indexPath) as! OfferedProducts
            cell.firstViewController = self
            return cell
        default:
            let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "Offers", for: indexPath) as! Offers
            return cell
        }
    }

您看到万一0（我的第一个单元格）我添加了它

而且效果很好
