VideoPlayer 自动播放 SwiftUI 问题

Question

我正在尝试让 VideoPlayer 使用视频控制器自动播放，但我似乎无法弄明白！我应该怎么办？我是 SwiftUI 的新手。

struct VideoView: View {
    // MARK: - PROPERTIES
    
    //: BINDING
    @Binding var videoView: Bool
    
    //: STATE
    @State var player = AVPlayer()
    @State var isplaying = true
    @State var showcontrols = true
    
    //: VAR
    var allowsPictureInPicturePlayback : Bool = true
    var wrkflw: Wrkflw
    
    // MARK: - BODY
    
    var body: some View {
        
        VideoPlayer(wrkflw: wrkflw, player: $player)
            .edgesIgnoringSafeArea(.all)
            
            .onAppear {
                player.play()
            }
        
    }
}

标记：- 视频控制器

struct VideoPlayer : UIViewControllerRepresentable {
    
    var wrkflw: Wrkflw
    @Binding var player : AVPlayer
    
    func makeUIViewController(context: Context) ->  UIViewController {
        
        
        let player = AVPlayer(url: wrkflw.wrkvideo)
        let controller = AVPlayerViewController()
        
        controller.player = player
        controller.showsPlaybackControls = true
        controller.exitsFullScreenWhenPlaybackEnds = true
        controller.allowsPictureInPicturePlayback = true
        
        return controller
    }
    
    func updateUIViewController(_ uiViewController: UIViewController, context: Context) {
        
        
    }
}

Answer 1

最简单的解决方案是将 AVPlayer 引用从 VideoView 传递给 VideoPlayer。您可以使用 player.replaceCurrentItem 以便您可以设置正确的 URL 但保持相同的播放器引用。

确保删除 VideoPlayer

中的 let player... 行


struct VideoView: View { // MARK: - PROPERTIES
    
    //: BINDING
    
    @Binding var videoView: Bool
    
    //: STATE
    @State var player = AVPlayer()
    @State var isplaying = true
    @State var showcontrols = true
    
    //: VAR
    var allowsPictureInPicturePlayback : Bool = true
    var wrkflw: Wrkflw
    
    // MARK: - BODY
    
    var body: some View {
        
        VideoPlayer(wrkflw: wrkflw, player: player)
            .edgesIgnoringSafeArea(.all)
        
            .onAppear {
                player.replaceCurrentItem(with: AVPlayerItem(url: wrkflw.wrkvideo)) //<-- Here
                player.play()
            }
        
    }
}
// MARK: - VIDEO CONTROLLER

struct VideoPlayer : UIViewControllerRepresentable {
    
    var wrkflw: Wrkflw
    var player : AVPlayer
    
    func makeUIViewController(context: Context) ->  UIViewController {
        
        //<-- Here
        
        let controller = AVPlayerViewController()
        
        controller.player = player
        controller.showsPlaybackControls = true
        controller.exitsFullScreenWhenPlaybackEnds = true
        controller.allowsPictureInPicturePlayback = true
        
        return controller
    }
    
    func updateUIViewController(_ uiViewController: UIViewController, context: Context) {
        
        
    }
}
