AVkit Bundle.main.path找不到forResource

Question

我想在forResoure中显示我的视频的不同名称，所以我更改了Bundle.main.path（forResource：“已更改”），但它不起作用，它找不到合适的视频。我做错了什么？ 提前谢谢。

自：

if let path=Bundle.main.path(forResource: "video1", ofType: "mp4")

TO：

if let path=Bundle.main.path(forResource: "\(datForVideo.name)", ofType: "mp4")

对complet代码可能有点帮助：

@IBAction func videoInfoButton(_ sender: Any) {
    if let path=Bundle.main.path(forResource: "video1", ofType: "mp4"){
        let video=AVPlayer(url: URL(fileURLWithPath: path))
        let videoPlay=AVPlayerViewController()
        videoPlay.player=video

        present(videoPlay, animated: true, completion: {

            video.play()
        })
    }
}

更改为：

@IBAction func videoInfoButton(_ sender: Any) {
    if let path=Bundle.main.path(forResource: "\(datForVideo.name)", ofType: "mp4"){
        let video=AVPlayer(url: URL(fileURLWithPath: path))
        let videoPlay=AVPlayerViewController()
        videoPlay.player=video

        present(videoPlay, animated: true, completion: {

            video.play()
        })
    }
}
