Answer 1

It sets the brightness for the device on iPad, and iPhone, just like in the Settings. It changes the brightness even when the app closes, it is kind of annoying. You have to reset it back to default programmatically in the appropriate method.

You have to reopen app....set back to default, or go to your Settings and change it back.

You will need to save the value you want to set yourself in your NSUserDefaults and call setBrightness: in your application delegate's applicationDidBecomeActive: method to restore the brightness.
