swift 。在应用启动时创建介绍视频

Question

我想在我的应用启动时播放本地视频作为介绍视频。用户不应该以任何方式取消或暂停视频，知道我该怎么做吗？

import AVKit
import AVFoundation

class GetInfoView: SKScene {

    var moviePlayer = AVPlayerViewController()
    var player = AVPlayer()

    override func didMoveToView(view: SKView) {

        player = AVPlayer(URL: NSURL(fileURLWithPath: NSBundle.mainBundle().pathForResource("intro", ofType: "mp4")!))
        moviePlayer.showsPlaybackControls = false
        moviePlayer.player = player

        self.view?.window?.rootViewController?.presentViewController(moviePlayer, animated: false){
        moviePlayer.player?.play()
        }
    }
}

我试过了，但是当它运行时 player = AVPlayer(URL: NSURL(fileURLWithPath: NSBundle.mainBundle().pathForResource("intro", ofType: "mp4")!)) 它崩溃了。

错误:

"fatal error: unexpectedly found nil while unwrapping an Optional value"

我不知道问题出在哪里，我确实在构建中添加了“intro.mp4”

添加你的电影项目。File Inspector -> Project name -> Targets -> Project Name -> Build Phases -> Copy Bundle Resources -> + button
