You can't do this with public APIs. You could put an overlay to make the screen darker, but you can't adjust the hardware brightness.

Just put a view over everything, set usserInteractionEnabled=NO and adjust the alpha.

keep in mind that popovers and other views may still get on top of your overlay view
