Question

我正在尝试从捆绑目录播放视频,但我收到此错误:

这是我的实施:

import UIKit
import AVKit
import AVFoundation

    var playerVC = AVPlayerViewController()
    var playerView = AVPlayer()

    override func viewDidLoad() {
        super.viewDidLoad()
        self.playVideo()

    }


    func playVideo() {
        let documentsDirectory = FileManager.default.urls(for: .documentDirectory, in: .userDomainMask).last! as NSURL
        guard let fileURL  = documentsDirectory.appendingPathComponent("video.mp4") else{ return }
        self.playerView = AVPlayer(url:fileURL as URL)
        self.playerVC.player = playerView
        self.view.addSubview(self.playerVC.view)
        self.addChildViewController(self.playerVC)
        playerView.play()

    }

你们中的任何人都知道我做错了什么？我真的很感激你的帮助.

    var playerView = AVPlayer()

    override func viewDidLoad() {
        super.viewDidLoad()

    }

override func viewDidAppear(_ animated: Bool) {

       let fileURL = NSURL(fileURLWithPath: "video.mp4")

        playerView = AVPlayer(url: fileURL as URL)
        playerViewController.player = playerView
        self.present(playerViewController, animated: true) {
        self.playerViewController.player?.play()
        }
    }
