從全屏顯示一個單元格的視頻Swift

Question

所以我想要做的是我有一個UICollectionViewController與單元格的圖像和視頻，我希望它，所以當你點擊視頻它全屏播放視頻。我已經爲這些圖像製作了這個圖片，但是我不太清楚如何爲視頻執行此操作？因此，使用圖像時，點擊圖像（單元格），圖像將以黑色背景視圖進入屏幕中央。我想合併相同的東西，但與視頻，當然，視頻將播放等...

我從Firebase獲取視頻。

碼是什麼我對圖像：

import UIKit 
import Firebase 
import MobileCoreServices 
import AVFoundation 

    class ImagesAndVideosController: UICollectionViewController, UICollectionViewDelegateFlowLayout { 

lazy var messageImageView: UIImageView = { 
    let imageView = UIImageView() 
    imageView.translatesAutoresizingMaskIntoConstraints = false 
    imageView.layer.cornerRadius = 16 
    imageView.layer.masksToBounds = true 
    imageView.contentMode = .scaleAspectFill 
    imageView.isUserInteractionEnabled = true 
    imageView.addGestureRecognizer(UITapGestureRecognizer(target: self, action: #selector(handleZoomTap))) 

    return imageView 
}() 



func handleZoomTap(_ tapGesture: UITapGestureRecognizer) { 
    if message?.videoUrl != nil { 

     return 
    } 

    if let imageView = tapGesture.view as? UIImageView { 

      self.chatLogController?.performZoomInForStartingImageView(imageView) 
    } 
} 

var startingFrame: CGRect? 
var blackBackgroundView: UIView? 
var startingImageView: UIImageView? 

func performZoomInForStartingImageView(_ startingImageView: UIImageView) { 

    self.startingImageView = startingImageView 
    self.startingImageView?.isHidden = true 

    startingFrame = startingImageView.superview?.convert(startingImageView.frame, to: nil) 

    let zoomingImageView = UIImageView(frame: startingFrame!) 
    zoomingImageView.backgroundColor = UIColor.red 
    zoomingImageView.image = startingImageView.image 
    zoomingImageView.isUserInteractionEnabled = true 
    zoomingImageView.addGestureRecognizer(UITapGestureRecognizer(target: self, action: #selector(handleZoomOut))) 

    if let keyWindow = UIApplication.shared.keyWindow { 
     blackBackgroundView = UIView(frame: keyWindow.frame) 
     blackBackgroundView?.backgroundColor = UIColor.black 
     blackBackgroundView?.alpha = 0 
     keyWindow.addSubview(blackBackgroundView!) 

     keyWindow.addSubview(zoomingImageView) 

     UIView.animate(withDuration: 0.5, delay: 0, usingSpringWithDamping: 1, initialSpringVelocity: 1, options: .curveEaseOut, animations: { 

      self.blackBackgroundView?.alpha = 1 
      self.inputContainerView.alpha = 0 

      // math? 
      // h2/w1 = h1/w1 
      // h2 = h1/w1 * w1 
      let height = self.startingFrame!.height/self.startingFrame!.width * keyWindow.frame.width 

      zoomingImageView.frame = CGRect(x: 0, y: 0, width: keyWindow.frame.width, height: height) 

      zoomingImageView.center = keyWindow.center 

     }, completion: { (completed) in 
      //     do nothing 
     }) 

    } 
} 
func handleZoomOut(_ tapGesture: UITapGestureRecognizer) { 
    if let zoomOutImageView = tapGesture.view { 
     //need to animate back out to controller 
     zoomOutImageView.layer.cornerRadius = 16 
     zoomOutImageView.clipsToBounds = true 

     UIView.animate(withDuration: 0.5, delay: 0, usingSpringWithDamping: 1, initialSpringVelocity: 1, options: .curveEaseOut, animations: { 

      zoomOutImageView.frame = self.startingFrame! 
      self.blackBackgroundView?.alpha = 0 
      self.inputContainerView.alpha = 1 

     }, completion: { (completed) in 
      zoomOutImageView.removeFromSuperview() 
      self.startingImageView?.isHidden = false 
     }) 
    } 
} 

}

我很抱歉，如果我提出沒有多大意義的代碼，我相信大家都知道，這東西是超級保密的，所以我不得不剪切和粘貼足以顯示，但不是全部。我再次道歉。 我也有一個播放按鈕，所以當有一個視頻加載到收藏視圖中時，它會知道並在其上面放置播放按鈕，以便播放視頻，但視頻播放在單元內部，這就是爲什麼我希望它能夠到達中心（就像你在大多數應用中看到的那樣）。

謝謝你這麼多！我希望我提供了足夠的信息？

我已經創建了播放視頻的這種方法。

func playVideo() { 
    guard let path = Bundle.main.path(forResource: "Video", ofType:"mp4") else { 
     debugPrint("video.m4v not found") 
     return 
    } 
    let player = AVPlayer(url: URL(fileURLWithPath: path)) 
    let playerController = AVPlayerViewController() 
    playerController.player = player 
    present(playerController, animated: true) { 
     player.play() 
    } 
}
