I've been trying to find some kind of tutorial or information of any kind on some sort of file being read on app startup.

The scenario would be:

1. App Starts up
2. App checks for for file on iOS device hard drive to determine existing settings
3. If there are no existing settings, the app will then take data in and create existing settings, and save it to the iOS device to be read upon app startup the next time the app is run.

I tried to be as clear as possible. If this does not make sense, let me know and I will try to clarify further.
