How to programmatically silence the ringer or change the ringer tone on iOS5

Question

Is there a way to reduce the volume of the ringer or change the ringer tone on iOS5?

I checked out the Celestial framework, but can't instantiate AVSystemController. :-(

I don't care if this get's the app rejected in the AppStore as it will never be submitted.

Answer 1

Yes. Use AVSystemController. You don't instantiate it. It's a singleton.

[[AVSystemController sharedAVSystemController] setVolumeTo:10.0 forCategory:@"Ringtone"];
