MPMoviePlayerController在5秒后停止播放 - Swift [英] MPMoviePlayerController Stops Playing After 5 seconds - Swift

问题描述

我有一个视频，我正在尝试使用MPMoviePlayerController播放它加载正常，但在5秒后切断。我找到了这篇文章，但它并不适用于swift。

I have a video I'm trying to play using MPMoviePlayerController and it loads fine, but cuts out after 5 seconds. I found this post, but it isn't really applicable for swift.

MPMoviePlayerController在5s后停止播放视频

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)

    }

}

推荐答案

你的可以吗？ ePlayer 超出范围？您是否尝试将其设为成员变量？

Could your moviePlayer be going out of scope? Have you tried making it a member variable?

moviePlayer 是的局部变量viewDidLoad ，所以一旦该功能完成，我看不出你的玩家不会被解除分配的任何理由。

moviePlayer is a local variable of viewDidLoad, so once that function finishes, I don't see any reason why your player would not be deallocated.

如果你改为使用它该类的变量，其生命周期将延长以匹配您班级的生命周期。

If you instead make it a variable of the class, its lifetime will be extended to match your class's lifetime.

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()
        // ...
    }
