Notified when media player opens from UIWebView?

Question

I have got a UIViewController in my app with a UIWebView in it. The UIWebView is fixed-size and configured to open any links in a new UIViewController (browser). This works, but when I try clicking a video like YouTube or Vimeo from within the web view, it opens on top of the view controller. This would normally not be a problem, but I have an overlapping view that needs to get a message to move out of the way when this happens.

Is there a notification or any other way my view controller can get notified when a media player pops out of the UIWebView? I really need this to work better, because it's really ugly the way it currently is.

Thanks!

Unfortunately, there’s no kind of direct control or notifications of loading, progress, quitting, etc. However, you can get some indirect notifications based on your application’s window state: add in your view controller

[[NSNotificationCenter defaultCenter]
addObserver:self
selector:@selector(windowNowVisible:)
name:UIWindowDidBecomeVisibleNotification
object:self.view.window
];

[[NSNotificationCenter defaultCenter]
addObserver:self
selector:@selector(windowNowHidden:)
name:UIWindowDidBecomeHiddenNotification
object:self.view.window
];

to get these called when the YouTube window is shown and goes away respectively.

- (void)windowNowVisible:(NSNotification *)notification
{
   NSLog(@"Youtube/ Media window appears");
}


- (void)windowNowHidden:(NSNotification *)notification 
{
   NSLog(@"Youtube/ Media window disappears."); 
}

and hey, if that’s all you require by way of notification you’re good!
