I'm using a native extension to deal with the iPhone's mute button (http://extensionsforair.com/extensions/mute-button/) but it seems to loose it's way when the application goes into background mode. So what I'm trying to do is figure out when my application regains focus so I can reset it.
I try to do this using:
But whatever I do on my phone - BecomeActive not BecomeDeActive are never called. Do I understand this concept correctly or am I doing something wrong?
Thanks in advance
