Is there a concrete check to see if a user has accepted a phone call?

I know when a call is accepted applicationWillResignActive and applicationWillEnterBackground both get called. But they 开发者_开发百科seem to also get called for some other cases.

Is there a way to check if the user has ANSWERED the incoming phone call rather than decline or let it ring out.

As there maybe cases when the app gets a phone call while the app is already in the background and I need to be able to get some code to execute.(Hope I havent been to vague)

Many Thanks, -Code

Check out the Core Telephony framework, and the CTCallCenter object. I think it does what you're asking for...
