向iOS应用程序注册添加循环mp4后台

当用户登录到他们的社交媒体帐户时，我希望最终应用这段代码，让我的应用程序看起来更好一些。我已经尝试了下面的代码，但我的应用程序似乎在mp4结束后就崩溃了

import UIKit

import AVFoundation

class ViewController: UIViewController {

  var avPlayer: AVPlayer!
  var avPlayerLayer: AVPlayerLayer!
  var paused: Bool = false

  override func viewDidLoad() {
    super.viewDidLoad()
    let theURL = Bundle.main.url(forResource: "Yeet", withExtension: "mp4")

    avPlayer = AVPlayer(url: theURL!)
    avPlayerLayer = AVPlayerLayer(player: avPlayer)
    avPlayerLayer.videoGravity = AVLayerVideoGravity.resizeAspectFill
    avPlayer.volume = 0
    avPlayer.actionAtItemEnd = AVPlayer.ActionAtItemEnd.none

    avPlayerLayer.frame = view.layer.bounds
    view.backgroundColor = UIColor.clear;
    view.layer.insertSublayer(avPlayerLayer, at: 0)

    NotificationCenter.default.addObserver(self, selector: Selector(("playerItemDidReachEnd:")), name:       NSNotification.Name.AVPlayerItemDidPlayToEndTime, object: avPlayer.currentItem)
  }

    @objc func playerItemDidReachEnd(notification: NSNotification) {
    let p: AVPlayerItem = notification.object as! AVPlayerItem
      p.seek(to: CMTime.zero)
  }

  override func viewDidAppear(_ animated: Bool) {
    super.viewDidDisappear(animated)
    avPlayer.play()
    paused = false
  }

  override func viewDidDisappear(_ animated: Bool) {
    super.viewDidDisappear(animated)
    avPlayer.pause()
    paused = true
  }
  override var preferredStatusBarStyle: UIStatusBarStyle {
    return .lightContent
  }

}

你试过使用吗

看起来像是针对iOS 10+设备的@iwasrobed。下面是示例代码：

private var looper: AVPlayerLooper?

...

let queuePlayer = AVQueuePlayer(playerItem: item)
looper = AVPlayerLooper(player: queuePlayer, templateItem: item)
videoPlayerLayer.player = queuePlayer

要在离开视图后禁用循环，请在末尾添加以下代码：

looper?.disableLooping()
