swift - Swift 中的 AVPlayerView 崩溃

Question

在我的 macOS 应用程序中，我有一个带有AVPlayerView. 从 Xcode 运行时，窗口打开并播放视频。但是，当我导出（存档>复制应用程序）应用程序并打开它时，AVPlayerView 崩溃的窗口。

我怀疑问题是应用程序导出时应用程序无法访问视频文件。

import Cocoa
import AVKit

class IntroVC: NSViewController{
    override func viewDidLoad() {
        super.viewDidLoad()
        avViewConfig()
    }
    @IBOutlet weak var avView: AVPlayerView!
    
    
    func avViewConfig(){
        
        if let filePath = Bundle.main.path(forResource: "one", ofType: ".mp4") {
            let filePathURL = NSURL.fileURL(withPath: filePath)
            
            let player = AVPlayer(url: filePathURL)
            
            avView.player = player
            avView.player?.play()
        }
    }
}

我通过将视频文件直接拖到项目文件夹中来添加它。

仍然不知道问题是什么，但从AVPlayerView情节提要中删除并以编程方式添加一个似乎已经解决了这个问题。

class IntroVC: NSViewController{
    override func viewDidLoad() {
        super.viewDidLoad()
        avViewConfig()
        avPlayerView.frame = self.view.frame
        view.addSubview(avPlayerView)
    }
    
    var avPlayerView = AVPlayerView()
    
    func avViewConfig(){
        
        if let filePath = Bundle.main.path(forResource: "one", ofType: ".mp4") {
            let filePathURL = NSURL.fileURL(withPath: filePath)

            let player = AVPlayer(url: filePathURL)

            avPlayerView.player = player
            avPlayerView.player?.play()
        }
    }
}
