iphone sdk - detect user or light input

Question

I'm writing a little application and have fallen at the first hurdle nearly! I wanted to have an action happen when the light level dropped below a certain threshold. I've since found out you cannot access the light meter in the SDK, so I am thinking of another way of doing it.

(I assume I am correct in saying you cannot detect the light level?? - in my app, I ideally wanted to call an event when it goes dark...)

Could I somehow call an event ANY other way when the light level drops??

thanks for any help!

You need to use IOKit (the IOHID stuff) to detect Ambient Light Sensor events. There's no AppStore-compatible way to do it.
