MPMoviePlayerController自定義控件（子視圖）

Question

我想爲MPMoviePlayerController創建自定義控制器。一切正常，按鈕，但當我旋轉設備，子視圖（視頻控制器）不會更新佈局，以適應屏幕。

override func viewDidLoad() { 
    super.viewDidLoad() 

    // Do any additional setup after loading the view. 

    moviePlayer = MPMoviePlayerController(contentURL: urlVideo) 
    moviePlayer.movieSourceType = MPMovieSourceType.Unknown 
    moviePlayer.view.frame = self.view.bounds 
    moviePlayer.scalingMode = MPMovieScalingMode.None 
    moviePlayer.controlStyle = MPMovieControlStyle.None 
    moviePlayer.shouldAutoplay = true 
    moviePlayer.view.backgroundColor = UIColor.blackColor() 
    self.view.addSubview(moviePlayer.view) 
    moviePlayer.prepareToPlay() 
    moviePlayer.play() 

    var tapGestureRecognizer: UITapGestureRecognizer = UITapGestureRecognizer(target: self, action: "handleTapGestureRecognizer") 
    tapGestureRecognizer.delegate = self 
    self.view.addGestureRecognizer(tapGestureRecognizer) 

    // Do any additional setup after loading the view. 
    self.modalTransitionStyle = UIModalTransitionStyle.CrossDissolve; 

    //  NSNotificationCenter.defaultCenter().addObserver(self, selector: "rotated", name: UIDeviceOrientationDidChangeNotification, object: nil) 

    NSTimer.scheduledTimerWithTimeInterval(1.0, target: self, selector: "updatePlaybackTime:", userInfo: nil, repeats: true) 

    NSNotificationCenter.defaultCenter().addObserver(self, selector: Selector("playerPlaybackDidFinish:"), 
     name: MPMoviePlayerPlaybackDidFinishNotification, object: nil) 

    NSNotificationCenter.defaultCenter() .addObserver(self, selector: "movieOrientationChanged", name: UIDeviceOrientationDidChangeNotification, object: nil) 

    self.showController() 
} 

func showController() { 
    doneButton = UIButton(frame: CGRectMake(0, 22, 50, 30)) 
    doneButton.backgroundColor = UIColor.redColor() 
    doneButton.tintColor = UIColor.blackColor() 
    doneButton.setTitle("Done", forState: .Normal) 
    doneButton.addTarget(self, action: "exitVideo:", forControlEvents: UIControlEvents.TouchUpInside) 
    self.controllerView.addSubview(doneButton) 

    playButton = UIButton(frame: CGRectMake(0, self.view.bounds.size.height - 30, 60, 30)) 
    playButton.backgroundColor = UIColor.redColor() 
    playButton.tintColor = UIColor.blackColor() 
    playButton.addTarget(self, action: "pauseVideo:", forControlEvents: UIControlEvents.TouchUpInside) 

    self.controllerView.addSubview(playButton) 
    self.moviePlayer.view.addSubview(self.controllerView) 

} 

func movieOrientationChanged() { 
    moviePlayer.view.frame = self.view.bounds 
    controllerView.frame = self.moviePlayer.view.bounds 
    self.showController() 
} 

1 - 當視頻播放器打開

2 - 當視頻播放器旋轉爲橫向

3 - 當視頻播放器旋轉回縱向（還有一個紅色的在視頻播放器的中間的按鈕）

Answer 1

當showController()功能執行，您創建一個新的doneButton併爲playButton到您的視圖層次。所以當旋轉到橫向時，您將有兩個doneButton在相同的位置，兩個playButton在不同的Y軸上。

之快速固定：

func showController() { 
    self.controllerView.subviews.map{ $0.removeFromSuperview() } // Added this line 

    doneButton = UIButton(frame: CGRectMake(0, 22, 50, 30)) 
    doneButton.backgroundColor = UIColor.redColor() 
    doneButton.tintColor = UIColor.blackColor() 
    doneButton.setTitle("Done", forState: .Normal) 
    doneButton.addTarget(self, action: "exitVideo:", forControlEvents: UIControlEvents.TouchUpInside) 
    self.controllerView.addSubview(doneButton) 

    playButton = UIButton(frame: CGRectMake(0, self.view.bounds.size.height - 30, 60, 30)) 
    playButton.backgroundColor = UIColor.redColor() 
    playButton.tintColor = UIColor.blackColor() 
    playButton.addTarget(self, action: "pauseVideo:", forControlEvents: UIControlEvents.TouchUpInside) 

    self.controllerView.addSubview(playButton) 
    self.moviePlayer.view.addSubview(self.controllerView) 
}
