YTPlayerView doesn't always go to full screen

Question

I am trying to show a youtube video but sometimes the YTPlayerView is being displayed in full screen and sometimes not. I want it to be always in full screen. How can I achieve it?

ytView = [[YTPlayerView alloc] initWithFrame:self.view.bounds];
ytView.backgroundColor = self.view.backgroundColor;
ytView.delegate = self;
NSDictionary *playvarsDic = @{ @"controls" : @1, @"playsinline" : @0, @"autohide" : @1, @"showinfo" : @1, @"autoplay": @1, @"modestbranding" : @1 };
[ytView loadWithVideoId:firstImage.Source playerVars: playvarsDic];

Answer 1

Manually set playerView.webView.allowsInlineMediaPlayback = false in playerViewDidBecomeReady to force the player to go into webview.

Answer 2

To play youtube video in full screen you need to add one player property to play video in full screen.

fullscreen property: fs = 1 or 0

Update your dictionary like below:

NSDictionary *playvarsDic = @{ @"fs" : @1,
                                   @"controls" : @1,
                                   @"playsinline" : @0,
                                   @"autohide" : @1,
                                   @"showinfo" : @1,
                                   @"autoplay": @1,
                                   @"modestbranding" : @1 };

fullscreen property: fs

Setting this parameter to 0 prevents the fullscreen button from displaying in the player. The default value is 1, which causes the fullscreen button to display.

Hope this will help you to show your youtube video always in full-screen mode!
