如何在 AVQueuePlayer 中播放完最后一个项目后显示 sheet 视图?

How to show sheet view after last item finished playing in AVQueuePlayer?

我正在使用 AVQueuePlayer 播放一系列视频,但在播放完最后一个视频后,我看到 AVQueuePlayer 试图播放下一个视频,但没有剩余视频。我想要做的是在最后一个项目播放完毕后切换一个布尔值以显示 sheet 视图。你能帮我解决这个问题吗?感谢您的关注。我期待着您的回复。这是我的代码:

`struct Button : View {
            

@Binding var player : AVQueuePlayer
@Binding var isplaying : Bool
@State var showEnd = false
var removal: (() -> Void)? = nil
  
var body : some View {
    
    
     Button(action: {
       
     
            self.player.advanceToNextItem()
     }) {
         Image(systemName: self.isplaying ? "pause.fill" : "play.fill")
             .font(.title)
             .foregroundColor(.black)
             .padding(20)
     }
}
}


struct VideoPlayerS : UIViewControllerRepresentable {
        
@State var showEnd = false
var work : WorkoutDeS
@Binding var player : AVQueuePlayer
var playerLayer = AVPlayerLayer()
    
public func makeUIViewController(context: Context) -> AVPlayerViewController {
    let items = [
        
        AVPlayerItem(url: URL(fileURLWithPath: String(work.url1))),
        AVPlayerItem(url: URL(fileURLWithPath: String(work.url2)))
        
    ]
   let player = AVQueuePlayer(items: items)
       let controller = AVPlayerViewController()

       DispatchQueue.main.async {
          self.player = player
       }
    controller.player = player
    controller.videoGravity = .resizeAspectFill

  

    
    
    player.actionAtItemEnd = .none
    NotificationCenter.default.addObserver(forName: .AVPlayerItemDidPlayToEndTime, object: self.player.currentItem, queue: .main) { _ in
        self.player.seek(to: CMTime.zero)
        self.player.play()
    }
    player.play()
    

  
    
    return controller
}`

在队列玩家的 currentItem 上设置一个观察者。当调用观察者方法并且播放器中没有任何项目时,它已经播放了最后一个项目。
