ios - 从 iOS 设备播放视频文件

Question

我在我的 iOS 应用程序上播放视频。

func playVideo() {
        if let path = NSBundle.mainBundle().pathForResource("video", ofType:"mp4"),
            url = NSURL(fileURLWithPath: path),
            moviePlayer = MPMoviePlayerController(contentURL: url) {
                self.moviePlayer = moviePlayer
                moviePlayer.view.frame = self.view.bounds
                moviePlayer.prepareToPlay()
                moviePlayer.controlStyle = MPMovieControlStyle.None
                moviePlayer.view.frame = CGRect(x: 0, y: 0, width: UIScreen.mainScreen().bounds.width, height: UIScreen.mainScreen().bounds.height)
                moviePlayer.scalingMode = .AspectFill
                self.view.addSubview(moviePlayer.view)

if (oldMoviePlayer != nil){
                    println("Animation Run")
                    UIView.transitionFromView(oldMoviePlayer!.view, toView: moviePlayer.view, duration: 1.0, options: transitionOptions, completion: nil)
                }
                oldMoviePlayer = moviePlayer

        } else {
            debugPrintln("Ops, something wrong when playing video.m4v")
        }
    }

现在我的项目中保存了 video.mp4 文件。

如何从我的设备而不是项目中播放视频？

我可以从设备获取视频的路径和名称吗？
