当按下按钮时,我正在制作一个简单的iPad应用程序来播放电影.电影播放,电影结束时我想关闭AVPlayerView,然后返回主屏幕.目前,当视频完成时,它将保留在最后一帧.我的ViewController.Swift此刻.

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)
}
}

正如您所看到的,我认为actionAtItemEnd中可能存在某些内容,但我不确定如何实现它.谢谢.
