I notice on my iPhone, after a few seconds of being in direct sun light, the screen will adjust to become brighter, dimmer etc. I was wondering if there was a way to interact with this sensor?
I have an application which is used outside. When you go into direct light, it becomes very difficult to see the screen for a few momments, before it adjusts. And even then, it's not always as bright as I'd like it to be. I would like to implement a high contrast skin for outdoor viewing, and a low contrast for indoor viewing.
Is this possible to read light sensor data, and if so, how do I extract these sensor values?
I would assume there is a light sensor however, as the camera knows when to use the flash.
Try using GSEventSetBacklightLevel();, which requires <GraphicsServices/GraphicsServices.h>. This is how one can programmatically adjust the brightness levels. There is also a get option, so I think that may have the information you're after.
