不停地播放视频 (Swift)

Question

我想在我的 swift 应用程序上播放 10-20 秒的视频，但有时由于网速较慢，它会停止并且不会再次加载，直到我暂停并播放。所以我想做的是在流式传输之前，下载完整的视频，这样它就不会再次停在中间。这是我正在使用的代码

moviePlayer = MPMoviePlayerController(contentURL: url)
        moviePlayer.movieSourceType = MPMovieSourceType.File
        moviePlayer.controlStyle = MPMovieControlStyle.None
        moviePlayer.view.backgroundColor = UIColor.blueColor()
        moviePlayer.scalingMode = MPMovieScalingMode.AspectFit
        moviePlayer.repeatMode = MPMovieRepeatMode.None;
        moviePlayer.allowsAirPlay = false
        moviePlayer.shouldAutoplay = false
        moviePlayer.backgroundView.backgroundColor = UIColor.whiteColor()
        moviePlayer.view.frame = self.bounds
        self.addSubview(moviePlayer.view)

Answer 1

这就是我做的，添加了一个观察者来查找是否正在下载

NSNotificationCenter.defaultCenter().addObserver(self, selector: "videoStopped:", name: MPMoviePlayerLoadStateDidChangeNotification, object: moviePlayer)

使用 moviePlayer.currentPlaybackTime 和 moviePlayer.playableDuration

处理 videoStopped 函数 中的播放
