how to handle ios call interruptions in background

Question

I can handle call interruption using beginInterruption and endInterruption in the foreground application but when my application is in the background, how should I handle the call interruption?

Answer 1

Have the interruption handler which looks for the interruption state being kAudioSessionBeginInterruption and kAudioSessionEndInterruption. That should do the trick.

Do any processing (for interrruption handling) inside this handler.
