ios - 如何在 swift 中以编程方式在 Storyboard对象之前添加对象

Question

我正在制作带有视频背景的登录屏幕但是，在我添加背景后，所有 Main.storyboard 代码都位于我的视频后面(视频位于顶部)，如何将视频置于我的 View 后面？

代码:

 var moviePlayer : MPMoviePlayerController?
    let myPlayerView = UIView(frame: self.view.bounds)
    myPlayerView.backgroundColor = UIColor.clearColor()
    view.addSubview(myPlayerView)


    var urlpath = NSBundle.mainBundle().pathForResource("video", ofType: "m4v")
    let url:NSURL = NSURL.fileURLWithPath(urlpath!)!


    let myPlayer = AVPlayer(URL: url)
    myPlayer.play()


    let avLayer = AVPlayerLayer(player: myPlayer)
    avLayer.frame = myPlayerView.bounds
    myPlayerView.layer.addSublayer(avLayer)

只需将其添加到适当的位置即可。例如viewWillAppear。

myPlayerView.superview?.sendSubviewToBack(myPlayerView)
