迭代视频

Question

我试图让播放器遍历引用视频URL的字符串数组。如果我在代码中对其进行硬编码，我只能让它播放数组中的一个视频，但我无法进行迭代。

我已经播放了一个视频，而它是硬编码的，但没有迭代。

   var playerArray = [AVQueuePlayer]()
    var player = AVQueuePlayer()
   // var URLSArray = [URL]()
    var ItemArray = [AVPlayerItem]()
    var videos = ["video1", "video2","video3"]
    var playerController = AVPlayerViewController()


override func viewDidAppear(_ animated: Bool) {
    super.viewDidAppear(animated)
    let videoNum = (self.videos.count-1)
  //  var URLSArray = [URL]()
 //   for n in 0...videoNum{
 //       let pathString = (Bundle.main.path(forResource: videos[n], ofType: "mov"))
  //      let StrToURL  = NSURL(string: pathString!)
  //      URLSArray.append(StrToURL! as URL)
 //   }
    var ItemArray = [AVPlayerItem]()
 //  var playerController = AVPlayerViewController()
    for n  in 0...videoNum{
        let pathString = (Bundle.main.path(forResource: videos[n], ofType: "mov"))
        //print(pathString!)
        let StrToURL  = URL(string: pathString!)
       // print(StrToURL!)
       // ItemArray = [AVPlayerItem(url: StrToURL!)]
        ItemArray.append(AVPlayerItem(url:StrToURL!))
        print(n)
        print(ItemArray)
       // let player = AVPlayer(playerItem: ItemArray[0])
        player = AVQueuePlayer(items: [ItemArray[n]])

        player.play()
                   }


             //  playerController.player = player
              // present(playerController, animated: true) {
                //   player.play()
    }

我希望它完成播放一个视频并继续播放数组中的下一个视频，我如何从数组中对视频进行硬编码，但是如果我尝试迭代它，它就像 URL 不起作用一样。这就是它所说的 2019-06-14 13：08：44.718684-0400 视频[5439：1288491] NSURL 连接已完成，但出现错误 - 代码 -1002

仅声明玩家

var player = AVQueuePlayer()

在viewDidAppear中，将字符串数组映射到应用程序捆绑包中的 URL，然后将 URL 映射到播放器项。然后创建排队的播放器并开始播放。

override func viewDidAppear(_ animated: Bool) {
    super.viewDidAppear(animated)
    let videos = ["video1", "video2", "video3"]
    let videoURLs = videos.compactMap{ Bundle.main.url(forResource: $0, withExtension: "mov")}
    let itemArray = videoURLs.map{ AVPlayerItem(url: $0) }
    player = AVQueuePlayer(items: itemArray)
    player.play()
    //  playerController.player = player
    // present(playerController, animated: true) {
    //   player.play()
    // }
}
