If I'm using NSUserDefaults to store settings for my application, is there any way to make my app's settings "hidden" from being shown in the general Settings application on the iPhone?

I have looked for several hours for a good tutorial on how to store data for my command line program that I am writing in Objective-C. It seems like my options are NSUserDefaults, Plists, sqlite, or XML.
