问题描述

I have a MP4 video that I want to put on the launch screen. Like who when on image loads on the launch screen but now just a video. And I do know how to put a image on the launch screen but not a video any help?

推荐答案

您可以为主界面"创建自定义ViewController，并在LaunchScreen之后使用内部使用AVPlayer的方式使用它.很快就会是这样的:

You can create a custom ViewController for "Main Interface" and use it after the LaunchScreen with use AVPlayer inside. In swift will be something like this:

var player: AVPlayer?

override func viewDidLoad() {
    super.viewDidLoad()

    loadVideo()
}

private func loadVideo() {

    //this line is important to prevent background music stop
    do {
        try AVAudioSession.sharedInstance().setCategory(AVAudioSessionCategoryAmbient)
    } catch { }

    let path = NSBundle.mainBundle().pathForResource("your path", ofType:"mp4")

    player = AVPlayer(URL: NSURL(fileURLWithPath: path!))
    let playerLayer = AVPlayerLayer(player: player)

    playerLayer.frame = self.view.frame
    playerLayer.videoGravity = AVLayerVideoGravityResizeAspectFill
    playerLayer.zPosition = -1

    self.view.layer.addSublayer(playerLayer)

    player?.seekToTime(kCMTimeZero)
    player?.play()
}
