NSUserDefaults intitial setup

I'm saving a few user settings in NSUserDefaults. If these settings have not been modified by the user, I'd like the app to use presets.

How should I set this up so the app first checks if settings have been modified and if not, sets presets?

Checking if [[NSUserDefaults standardDefaults]objectForKey: @"setting1"] == nil ? Then setting a preset if it is not?

[[NSUserDefaults standardUserDefaults] registerDefaults:dictionary];

https://developer.apple.com/library/mac/#documentation/Cocoa/Reference/Foundation/Classes/NSUserDefaults_Class/Reference/Reference.html#//apple_ref/doc/uid/20000318-CIHDDCDB

Call that from your applicationDidFinishLaunchingWithOptions: method that sets up whatever defaults you may need.

Look at the NSUserDefaults docs for registerDefaults. This allows you to have default values until the user changes them, then they have no effect.
