ios之如何同时播放2个视频

我正在尝试通过 MPMoviePlayerController 在一个屏幕上播放两个视频，但每次只播放其中一个。 这是我的播放视频功能:

func playVideo() { 
    let url = NSURL(string: videoUrls[videoNumber]) 
    moviePlayer = MPMoviePlayerController(contentURL: url) 
    if let player = moviePlayer { 
        player.view.frame = CGRect(x: 0, y: 200, width: 200, height: 200) 
        player.shouldAutoplay = true 
        player.prepareToPlay() 
        player.scalingMode = .AspectFill 
        player.controlStyle = .None 
        player.allowsAirPlay = false 
        self.view.addSubview(player.view) 
    } 
 
    let backUrl = NSURL(string: videoUrls[videoNumber+1]) 
    backPlayer = MPMoviePlayerController(contentURL: backUrl) 
    if let player = backPlayer { 
        player.view.frame = CGRect(x: 0, y: 0, width: 200, height: 200) 
        player.shouldAutoplay = true 
        player.prepareToPlay() 
        player.scalingMode = .AspectFill 
        player.controlStyle = .None 
        player.allowsAirPlay = false 
        self.view.addSubview(player.view) 
    } 

请您参考如下方法:

Note

Although you can create multiple MPMoviePlayerController objects and present their views in your interface, only one movie player at a time can play its movie.

如果你想同时播放两部电影，请查看 AVPlayerLayer 和 AVSynchronizedLayer
