iPhone read value from light meter.

I am not proficient with the iPhone. I just need a class that can get a value from the ambient light meter on the front of the phone if this is possible. Thanks Bill ## Deliverables This sounds simple to me but I'm not sure how to do it. I simply need a class that I can use in xcode to read from the ambient light meter on the front of an iPhone. I have the user interface of my app already written, I just need to be able to set the number into the appropriate variable. THANKS
