Question

My app works fine in portrait orientation but when i turn to landscape mode I see white square trough half view.

What's the problem?

Code of movie player

    moviePlayer = MPMoviePlayerController(contentURL: stream)
    moviePlayer.view.frame = CGRect(x: 0, y: 0, width: self.view.frame.size.width, height: self.view.frame.size.height)
    moviePlayer.view.sizeToFit()
    self.view.addSubview(moviePlayer.view)
    moviePlayer.fullscreen = true
    moviePlayer.controlStyle = MPMovieControlStyle.Embedded
}

Answer 1

You need to resize moviePlayer when its superview's bounds change.

One solution is to move this line:

moviePlayer.view.frame = CGRect(x: 0, y: 0, width: self.view.frame.size.width, height: self.view.frame.size.height)

Into viewWillLayoutSubviews (if this is a view controller subclass) or layoutSubviews (if this is a view subclass).

Another is to use auto-layout instead of manual layout.

Answer 2

As you are not using autolayout , you must update the view's frame when orientation is done, to do so you can use the method

override func viewWillTransitionToSize(size: CGSize, withTransitionCoordinator coordinator: UIViewControllerTransitionCoordinator) {

}

This methods is called every time when a orientation change is done and here you can update or set the frame of view to your needs.

Another way is to use Autolayout which is much effective.
