Check out this article. There's some code you can download at the bottom. Also, a related question on SO where I found the link.

Answer 2

In the 3.0 SDK the UIDevice class has the proximityState and proximityMonitoringEnabled properties.

BOOL buttonPressed = [UIDevice currentDevice].proximityState;

... gives you the current state.

Keep in mind that the iPod Touch does not have a proximity sensor.

An official answer by an Apple rep is on the Apple Dev Forums (login required):

There's no supported way to get at the ambient light sensor. If you'd like to see such support added in the future, I encourage you to file a bug describing your requirements. While we may have seen similar requests many times before, a fresh bug report will allow you to express your needs in your own terms, and allow iOS engineering to gauge the level of demand. http://developer.apple.com/bugreporter

I got to know that we could subclass UIApplication and just override the method, Found the Info at Cory Larsons Link Here
