I am developing an iPhone application and I need to adjust the brightness of the screen through my application, in the same way as we do through the Settings app.

I have searched but have not found a solution.

You can use:

[[UIScreen mainScreen] setBrightness:1.0];

But only on iOS 5. Not supported on earlier iOS versions.

If you require compatibility with older iOS versions, try a black overlay on top of your application's main window with partial alpha. I used it in an iPad app - only downside is that it won't darken elements like popovers.

Check out the brightness property of UIScreen. This is a new API in iOS 5. You can't do it in older versions.
