ios - 使用 Avplayer/kit 问题播放本地视频

Question

每当我运行该项目时，它都会调出视频播放器，但视频不播放 . 我该如何解决？如果图片中的代码不够清楚，这里是代码:

import UIKit
import AVKit
import AVFoundation


class ViewController: UIViewController {

    let avPlayerViewController = AVPlayerViewController()
    var avPlayer:AVPlayer?

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

        let urlPathString = Bundle.main.path(forResource: "small", ofType: "mp4")

        if urlPathString != nil {

            let movieUrl = NSURL(fileURLWithPath: "/Users/kevingerman/Desktop/Pioneer News Season 2 Episode 1.mp4")

            self.avPlayer = AVPlayer(url: movieUrl as URL)
            self.avPlayerViewController.player = self.avPlayer

        }
    }



    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }


    @IBAction func playButtonTapped(_ sender: AnyObject) {
        //Trigger the video to play
        self.present(self.avPlayerViewController, animated: true) { () -> Void in self.avPlayerViewController.player?.play()    }


    }

Answer 1

评论中提出的解决方案和@Guan 回答的都是正确的。

你的urlPathString在这里实际上是nil，

让它工作——

1- Either add the Target Membership, as suggested in the comment and the answer above or

执行以下操作

1.1- Delete the small.mp4 from bundle, make sure you move it to trash

2.1 - Go to trash and drag and drop your mp4 file into the project again, you will get a window like this -

在将其添加回来时确保您 -

Check the projectTarget checkbox like the screenshot below -

确保文件名为small.mp4
