MPMoviePlayerController停止播放5秒後 - Swift

Question

我有一個視頻，我試圖播放使用MPMoviePlayerController，它加載正常，但5秒後切出。我發現了這篇文章，但它並不適用於swift。

MPMoviePlayerController stops playing the video after 5s

這裏是我的代碼。

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是否會超出範圍？你有沒有試過把它變成一個成員變量？

moviePlayer是一個局部變量viewDidLoad，所以一旦該函數完成，我看不到任何原因，您的球員不會被釋放。

如果您將其作爲課程的一個變量，則其生命週期將延長以符合課程的使用期限。

像

class ViewController: UIViewController { 

var player: MPMoviePlayerController? 

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