ios - 无法使 mediaPlayer View 在 UIView 内水平旋转

Question

我试图将视频播放器(medialPlayer.view)置于 UIView(videoPlayerView)的中心。但由于某种原因，它没有在中心对齐。谁能告诉我该怎么做并解释下面的代码中有什么问题？

//代码如下

 @IBOutlet var videoPlayerView: UIView!

var moviePlayer:MPMoviePlayerController!

override func viewDidLoad() {
    super.viewDidLoad()

    var url:NSURL = NSURL(string: "http://jplayer.org/video/m4v/Big_Buck_Bunny_Trailer.m4v")!

    moviePlayer = MPMoviePlayerController(contentURL: url)
    let frameWidth = self.videoPlayerView.frame.size.width
    let frameHeight = self.videoPlayerView.frame.size.height

    moviePlayer.view.frame = CGRect(x: 0, y: 0, width: frameWidth, height: frameHeight)


    self.videoPlayerView.addSubview(moviePlayer.view)
    moviePlayer.fullscreen = true

    moviePlayer.controlStyle = MPMovieControlStyle.Embedded

}

Answer 1

在 viewWillAppear 中尝试将播放器 View 居中:

moviePlayer.view.center = videoPlayerView.center

看看这是否会改变什么。
