Receiving Notifications with App in background mode

Question

I have an app, that will keep track of everything the user do in the iPod app. To do this, I added few observers to NSNotificationCenter, like MPMusicPlayerControllerNowPla

Answer 1

As I explained here iOS receive Media Player Notifications when app is in background, there seems no way to get notifications from iPodMusicPlayer.

About Omar Raul Qazi answer:

a) i tried and I had no success. The music kept going down when pressing home button. I think this background flag only works for normal AudioSessions and not for MPMusicPlayer...

b) I am not sure this would work and I don't think Apple would like it when looking for approval

c) You can run in background only synchronous task. You cannot wait there for a notification. Am I wrong?
