iOS 9中的MPMoviePlayer

AVPlayerViewController是UIViewController的子类。因此，不要使用常规的视图控制器，而是按照以下步骤创建自定义电影播放器​​控制器：

不要将AVPlayerViewController子类化。不支持覆盖此类的方法，并导致未定义的行为。

尝试这样：

import UIKitimport AVKitimport AVFoundationclass MoviePlayerViewController: AVPlayerViewController {    override func viewDidLoad() {        super.viewDidLoad()        player = AVPlayer(URL: url)        videoGravity = AVLayerVideoGravityResizeAspect        showsPlaybackControls = true        //  player?.play() // uncomment this line to autoplay        NSNotificationCenter.defaultCenter().addObserver(self, selector: "didPlayToEndTime", name: AVPlayerItemDidPlayToEndTimeNotification, object: nil)    }    func didPlayToEndTime(){        print("didPlayToEndTime")    }    override func didReceiveMemoryWarning() {        super.didReceiveMemoryWarning()        // Dispose of any resources that can be recreated.    }}

要将其用作背景，可以执行以下操作：

import UIKitimport AVKitimport AVFoundationclass ViewController: UIViewController {    let moviePlayerController = AVPlayerViewController()    var aPlayer = AVPlayer()    func playBackgroundMovie(){        if let url = NSBundle.mainBundle().URLForResource("video", withExtension: "mov") { aPlayer = AVPlayer(URL: url)        }        moviePlayerController.player = aPlayer        moviePlayerController.view.frame = view.frame        moviePlayerController.view.sizeToFit()        moviePlayerController.videoGravity = AVLayerVideoGravityResizeAspect        moviePlayerController.showsPlaybackControls = false        aPlayer.play()        view.insertSubview(moviePlayerController.view, atIndex: 0)    }    func didPlayToEndTime(){        aPlayer.seekToTime(CMTimeMakeWithSeconds(0, 1))        aPlayer.play()    }    override func viewDidLoad() {        super.viewDidLoad()        playBackgroundMovie()        NSNotificationCenter.defaultCenter().addObserver(self, selector: "didPlayToEndTime", name: AVPlayerItemDidPlayToEndTimeNotification, object: nil)    }    override func didReceiveMemoryWarning() {        super.didReceiveMemoryWarning()        // Dispose of any resources that can be recreated.    }}
