NSUserDefaults: How to know if a value does not exist?

Hi Guys and Gals,

I am saving some user settings using NSUserDefaults.

in viewdidload, I retrieve the settings, and apply. Now, if it is a first installation, then this setting does not exist. So, how to check if a setting exist or not?

I am using this code
int FCOLOR = [[NSUderDefaults standardUserDefaults] integerForKey:@"MyColor"];

Is there a way to detect if "MyColor" exist or not? Or I just have to manually check for the value (valid or nonvalid)?

Ta. Cheers.
