How to set initial values for NSUserDefault Keys?

Question

I want to set some initial values for my NSUserDefault keys so that the first run of the app has some reasonable initial settings. I thought I ran across a simple way to do

If you have many default values, let use ola's answer, otherwise this is good for a few params

NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];

if (![defaults boolForKey:USERDEFAULT_IS_INITIALIZED]) { 
    [defaults setBool:YES forKey:USERDEFAULT_IS_INITIALIZED];

    // Set initial values 
    ...

    [defaults synchronize];
}
