I am trying to use CTCallCenter in a background application to receive CTCallCente开发者_如何学Pythonr events. Is this possible?

Yes and No.... It's complicated.

If your application is running a background task, then yes you will get events in the background. The problem is that background task will timeout in ten minutes (currently). So you can only get call events for the first ten minutes after going into the background....
