I was just wondering whether iPhone developement allows light sensors to be used, as buttons or action elements??

I found this link online...

Possible to use Light Sensor as a Button? [Archive] - Touch Arcade

If anyone could shed some light on the issue, I'd appreciate the help?

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

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.

    The proximity sensor isn't the light sensor – SeniorShizzle Jul 13 '10 at 09:14
  • The ambient light sensor is NOT the same as the proximity sensor (says the person who's only feedback option is a comment as I'm not hip enough to down-vote a candidate answer) – Minok Nov 12 '13 at 22:27
