MPMoviePlayerController 在 5 秒后停止播放 - Swift

Question

我正在尝试使用 MPMoviePlayerController 播放一个视频，它可以正常加载，但 5 秒后会中断。我找到了这篇文章，但它并不真正适用于 swift。

MPMoviePlayerController stops playing the video after 5s

这是我的代码。

import MediaPlayer




class ViewController: UIViewController  {


override func viewDidLoad() {
    super.viewDidLoad()
    // Do any additional setup after loading the view, typically from a nib.



    var moviePlayer: MPMoviePlayerController?



let url = NSURL(string: "http://path/to/video.m3u8")

    moviePlayer = MPMoviePlayerController(contentURL: url)

    if let player = moviePlayer {

        player.view.frame = CGRect(x: 0, y: 0, width: self.view.frame.size.width, height: self.view.frame.size.height)
        player.view.sizeToFit()
        player.scalingMode = MPMovieScalingMode.None


        player.movieSourceType = MPMovieSourceType.Streaming
        //player.repeatMode = MPMovieRepeatMode.One


        player.play()

        self.view.addSubview(player.view)

        NSNotificationCenter.defaultCenter().addObserver(
            self,
            selector: "metadataUpdated",
            name: MPMoviePlayerTimedMetadataUpdatedNotification,
            object: nil)

    }

}

Answer 1

您的moviePlayer 会超出范围吗？您是否尝试过将其设为成员变量？

moviePlayer 是viewDidLoad 的局部变量，所以一旦该函数完成，我看不出有任何理由说明您的播放器不会被释放。

如果您改为将其设为类的变量，则其生命周期将延长以匹配您的类的生命周期。

类似

class ViewController: UIViewController {

var player: MPMoviePlayerController?

    override func viewDidLoad() {
        // ...
        self.player = MPMoviePlayerController(contentURL: url) // won't go out of scope at end of viewDidLoad()
        // ...
    }
