How do I get notified when a user opens my iPhone app while in a phone call?

问题

I need to adjust several views in the event that a user visits my app while in a phone call. Is there a best practice for being notified of this?

Thanks!

You want to check the statusBarFrame property of the shared UIApplication instance. Take a look at Resize for in-call status bar?.
