如何在Swift的UI中添加视频

要实现您的要求,您需要使用AVPlayerLayer

1. 添加UIView插座

   @IBOutlet weak var videoView: UIView!
   

2. 导入AVFoundation

3. 创建播放器变量

   var player : AVPlayer!
   var avPlayerLayer : AVPlayerLayer!
   

4. 将以下代码添加到viewDidLoad

   guard let path = Bundle.main.path(forResource: "Logo-Animation4", ofType:"mp4") else {
       debugPrint("Logo-Animation4.mp4 not found")
       return
   }
   player = AVPlayer(url: URL(fileURLWithPath: path))
   avPlayerLayer = AVPlayerLayer(player: player)
   avPlayerLayer.videoGravity = AVLayerVideoGravity.resize
   
   videoView.layer.addSublayer(avPlayerLayer)
   player.play()
   

5. 添加此方法

   override func viewDidLayoutSubviews() {
       super.viewDidLayoutSubviews()
       avPlayerLayer.frame = videoView.layer.bounds
   }
