ios - MPMovieController 不会在完成按钮上关闭

Question

我的电影文件启动没有问题。完成按钮不会关闭视频内容。不知道为什么？此外，快进和快退按钮只会导致黑屏。我认为我没有正确使用通知功能？

import Foundation
import UIKit
import MediaPlayer

class VideoViewController: UIViewController {

var moviePlayer:MPMoviePlayerController!

@IBAction func videoLaunch(sender: AnyObject) {
    playVideo()
}
func playVideo() {
let path = NSBundle.mainBundle().pathForResource("MyVideo", ofType:"mp4")
let url = NSURL.fileURLWithPath(path!)
moviePlayer = MPMoviePlayerController(contentURL: url)
if let player = moviePlayer {
player.view.frame = self.view.bounds
moviePlayer?.controlStyle = MPMovieControlStyle.Fullscreen
player.prepareToPlay()
self.view.addSubview(player.view)

}
}


override func viewDidLoad() {
    super.viewDidLoad()

    NSNotificationCenter.defaultCenter().addObserver(
        self,
        selector: "moviePlayBackDidFinish:",
        name: MPMoviePlayerPlaybackDidFinishNotification,
        object: moviePlayer)


    func moviePlayBackDidFinish(notification: NSNotification){
        self.view.removeFromSuperview()
    }



    }
}

Answer 1

您正在将播放器视图添加为子视图。按下完成按钮后，您应该将其删除（removeFromSuperview）。使用通知收听播放完成：

NSNotificationCenter.defaultCenter().addObserver(
self,
selector: "moviePlayBackDidFinish:",
name: MPMoviePlayerPlaybackDidFinishNotification,
object: moviePlayer)

和电影PlayBackDidFinish：

func moviePlayBackDidFinish(notification: NSNotification){
  // remove from superview
}

Answer 2

您应该像这样从您的超级视图中删除moviePlayer：

   func moviePlayBackDidFinish(notification: NSNotification){
        let moviePlayer:MPMoviePlayerController = notif.object as! MPMoviePlayerController

    moviePlayer.view.removeFromSuperview()
}

因为在您的情况下，您删除了 self.view
