如何使用 iOS swift 中的 AVPlayer 访问存在于 iOS 文件应用程序中的视频文件？

Question

我正在尝试访问存在于 iOS 文件应用程序中的视频文件。尝试使用 AVPlayer

播放视频

我可以访问这些视频，但过了一段时间，当我尝试访问同一视频时，AVPlayer 出现错误。

let filemgr = FileManager.default
let docsDirURL = try! filemgr.url(for: .documentDirectory, 
  in: .userDomainMask, appropriateFor: nil, create: true)

let lastComp = docsDirURL.lastPathComponent
let pathy = "\(docsDirURL)"

if let urls = lap.videoURLs {
  self.lap = lap
  for url in urls {
    let urlComps = "\(url)".components(separatedBy: "/")
    var urlpath = ""
    for (index, element) in urlComps.enumerated() {
      if index > 9{
        urlpath +=  element + "/"
      }
    }

    print(urlpath)
    var pathz = pathy.replacingOccurrences(of: lastComp, with: urlpath)
    pathz = String(pathz.dropLast(2))
    print(pathz)

    let finalURL = NSURL(string: pathz)
//  let playerItem = AVPlayerItem(url: url as URL)
    let playerItem = AVPlayerItem(url: finalURL! as URL)
    playerItem.addObserver(self, forKeyPath: "status", options: .new, 
      context: &itemStatusContext)
    self.playerItems.append(playerItem)

    if self.queuePlayer == nil {
      self.queuePlayer = AVPlayer(playerItem: playerItem)
    }
  }
}

我希望能像以前一样正常播放视频，但我只能访问它一分钟之类的时间，然后在收到错误消息后。

因此如错误"No such file or directory"所述，文件不存在。关于它存储在临时文件夹中的完整路径。可能您通过 UIDocumentPickerViewController 或类似组件导入了这些文件。您必须立即（同步）将提供的文件复制到您获取 URL 的同一代码块中，以避免出现这种情况。
