Make AVPlayer to full screen view in AVPlayerViewController, Swift

Question

I am new to swift and getting problem in making AVPlayerViewController.player go to full screen in ViewController: AVPlayerViewController

here is code I am using in viewDidAppear to play the video

    let path = NSBundle.mainBundle().pathForResource("video", ofType: "mp4")!
    let url = NSURL(fileURLWithPath: path)

    let player = AVPlayer(URL: url)
    self.player = player
    self.showsPlaybackControls = false
    self.player!.play()

I am making playBackControlls hidden, and required to make video view to full screen...

Answer 1

For adding AVPlayer to a view, I make a CALayer from it like this:

let playerLayer = AVPlayerLayer(player: player)

Then you need to add this layer to a view, for example, if you wrote that code in a ViewController, then you can do this:

self.view.layer.addSublayer(playerLayer)

Next, make sure that this layer is as big as the parent ViewController:

playerLayer.frame = self.view.layer.bounds

And now, you can choose any of these options to how to resize your video. Here, I used .resize assuming aspect ratio of video and the screen are the same

playerLayer.videoGravity = AVLayerVideoGravity.resize

Answer 2

I'd recommend following solution without adding extra layer:

in your ViewController: AVPlayerViewController in viewDidLoad() just set

videoGravity = .resizeAspectFill

According to documentation:

The video gravity determines how the video content is scaled or stretched within the bounds of the player view controller’s view. The player view controller supports the following video gravity values:

• resizeAspect
• resizeAspectFill
• resize

The default value is resizeAspect.
