I'm aware of NSUserDefaults for saving/restoring user preferences. What is the equivalent class for an application? For example, the application may have a "last run" field; or it may have a field for a unique identification of the device for use at the application level.
My intention is to keep the application's settings (not user's settings) out of the Settings Application, and not backup those settings in iTunes, Time Machine, {whatever}.
I'm getting a lot of noise for Java and C#, but not much for iOS/iPhone/iPad.
