解雇后AVPlayerViewController音频继续在后台播放

Question

我的目标是：

1. 记录一个视频
2. 在一个视图中显示它，并在一个循环
3. 上播放它，
4. 将它从视图
5. 中删除，其中包含一个新视频H 210G 211

问题：

步骤1-3起作用。然而，在我切换camera.showMoviePreview到false之后，音频继续在后台播放。

下面是我呈现视频的视图：

if camera.showMoviePreview {
                   
      CustomVideoPlayer(url: camera.previewURL)                    
                
}

这是我的AVPlayerViewController

struct CustomVideoPlayer: UIViewControllerRepresentable {
    
    ///URL of the video
    var url:URL?

    
    func makeUIViewController(context: Context) -> AVPlayerViewController {
        

        let controller = AVPlayerViewController()
        let playerLooper: AVPlayerLooper!

        
        let url: URL = url!
        let player1 = AVPlayer(url: url)
        
        player1.preventsDisplaySleepDuringVideoPlayback = true
        player1.allowsExternalPlayback = true
        
        controller.showsPlaybackControls = false
        
        controller.videoGravity = .resizeAspectFill
        controller.player = player1
        controller.player?.play()
        

        let playerItem = AVPlayerItem(url: url)
        let player = AVQueuePlayer(playerItem: playerItem)
        playerLooper = AVPlayerLooper(player: player, templateItem: playerItem)
        
        NotificationCenter.default.addObserver(forName: .AVPlayerItemDidPlayToEndTime, object: controller.player?.currentItem, queue: .main)
                   {  _ in
                       controller.player?.seek(to: CMTime.zero)
                       controller.player?.play()
                   }

        return controller
    }
    
    
    func updateUIViewController(_ uiViewController: AVPlayerViewController, context: Context) {
        
    }
}

我相信音频会继续播放，因为我没有卸载AVPlayerViewController，但我不确定正确的方法

Answer 1

简单地说，你可以用"onDisapear“方法停止视频，

1 .在类(而不是在AVPlayer中)中定义makeUIViewController属性。

2 .将CustomVideoPlayer(url: camera.previewURL)定义为如下视图：

var videoPlayer: some View{
    CustomVideoPlayer(url: camera.previewURL)
}

3 .使用int类：

if camera.showMoviePreview {
   videoPlayer
       .onDisappear {
           camera.videoPlayer.pause()
       }
}
