What I would like to do is simply make the iDevice fade the screen to black one the proximityState returns yes. However, I am not sure of how to enable it, or monitor it. Would someone be able to simply provide syntax of enabling and monitoring proximityState? The help would be highly appreciated for a new programmer like me.
Thanks! -Jake
