电影播放完毕后关闭 AVPlayer

Question

我正在制作一个简单的 iPad 应用程序来在按下按钮时播放电影。电影开始播放，电影结束后我想关闭 AVPlayerView 以便它返回主屏幕。目前，当视频结束时，它停留在最后一帧。我现在 ViewController.Swift。

import UIKit
import AVKit
import AVFoundation

class ViewController: UIViewController {
//MARK : Properties 

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

@IBAction func playButton(_ sender: AnyObject) {

    let movieURL = Bundle.main.url(forResource: "ElephantSeals", withExtension: "mov")!
    let player = AVPlayer(url: movieURL as URL)

    let playerViewController = AVPlayerViewController()

    playerViewController.player = player

    self.present(playerViewController, animated: true) {
        playerViewController.player!.play()
        }
//    player.actionAtItemEnd = playerViewController.dismiss(animated: true)
}
}

如您所见，我认为 actionAtItemEnd 中可能有一些内容，但我不确定如何实现它。谢谢。

Answer 1

调用 AVPlayerViewControllerDelegate。

在viewDidLoad中初始化delegate并实现这个方法

func playerViewControllerDidStopPictureInPicture(AVPlayerViewController) {
      AVPlayerViewController.dismiss(animated: true)
}

Answer 2

使用 NSNotificationCenter 你可以做到这一点。

 NotificationCenter.default.addObserver(self, selector: #selector(ViewController.playerDidFinishPlaying), name: NSNotification.Name.AVPlayerItemDidPlayToEndTime, object:  videoPlayer!.currentItem)

@objc func playerDidFinishPlaying(note: NSNotification) {
    // here you can do your dismiss controller logic
    AVPlayerViewController.dismiss(animated: true)
    print("Video Finished")
}

这是 swift 5.3 和 iOS 14.2 中的工作代码，试试这个让我知道...:)

import UIKit
import AVKit
import AVFoundation

class ViewController: UIViewController {
    
    let playerViewController = AVPlayerViewController()
    
    override func viewDidLoad() {
        super.viewDidLoad()
    }
    
    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
    }
    
    @IBAction func playButton(_ sender: AnyObject) {
        
        let movieURL = Bundle.main.url(forResource: "ElephantSeals", withExtension: "mp4")!
        let player = AVPlayer(url: movieURL as URL)
        
        playerViewController.player = player
        NotificationCenter.default.addObserver(self, selector: #selector(playerDidFinishPlaying), name: NSNotification.Name.AVPlayerItemDidPlayToEndTime, object: playerViewController.player?.currentItem)
        
        self.present(playerViewController, animated: true) {
            self.playerViewController.player!.play()
        }
    }
    
    
    @objc func playerDidFinishPlaying(note: NSNotification) {
        self.playerViewController.dismiss(animated: true)
    }
}

这里是objective c代码

[[NSNotificationCenter defaultCenter] addObserver:self 
selector:@selector(nextVideo:)  name:AVPlayerItemDidPlayToEndTimeNotification object:playerViewController.player.currentItem];

Swift 4

let playerController = AVPlayerViewController()

private func playVideo() {
    guard let path = Bundle.main.path(forResource: "p810", ofType:"mp4") else {
        debugPrint("video.m4v not found")
        return
    }
    let player = AVPlayer(url: URL(fileURLWithPath: path))
    playerController.player = player
    NotificationCenter.default.addObserver(self, selector: #selector(playerDidFinishPlaying), name: NSNotification.Name.AVPlayerItemDidPlayToEndTime, object: playerController.player?.currentItem)

    present(playerController, animated: true) {
        player.play()
    }
}

@objc func playerDidFinishPlaying(note: NSNotification) {
    playerController.dismiss(animated: true, completion: nil)
}
