我是 swift 和 tvOS 的新手。我想从 url 下载视频并将其显示在 ViewController 中。当我尝试使用 ios 设备时,视频已下载并且工作正常。但使用 tvOS 时,视频未下载。
为什么会这样..?
如何在 Apple TV 中下载和播放视频。
这是我的代码
让 backgroundSessionConfiguration = URLSessionConfiguration.background(withIdentifier: "backgroundSession")
backgroundSession = Foundation.URLSession(configuration: backgroundSessionConfiguration, delegate: self, delegateQueue: OperationQueue.main)
let url = URL(string: "myURl")!
downloadTask = backgroundSession.downloadTask(with: url)
downloadTask.resume()
func urlSession(_ session: URLSession, downloadTask: URLSessionDownloadTask, didFinishDownloadingTo location: URL){
let path = NSSearchPathForDirectoriesInDomains(FileManager.SearchPathDirectory.documentDirectory, FileManager.SearchPathDomainMask.userDomainMask, true)
let documentDirectoryPath:String = path[0]
let fileManager = FileManager()
let destinationURLForFile = URL(fileURLWithPath: documentDirectoryPath.appendingFormat("/file.mp4"))
if fileManager.fileExists(atPath: destinationURLForFile.path){
showFileWithPath(path: destinationURLForFile.path)
}
else{
do {
try fileManager.moveItem(at: location, to: destinationURLForFile)
// show file
showFileWithPath(path: destinationURLForFile.path)
}catch{
print("An error occurred while moving file to destination url")
}
}
}
