No probs Aaron,
there are two types of methods you can call on Obj C classes, the
most commonly used are your standard instance methods. If you look
at some of the standard docs' you will see these are prefixed by a
"-" the other type used at initialisation or for getting shared
instances are class methods and are prefixed with a "+"
Download AppKiDo and browse around some of the Cocoa classes and you
can see the class methods clearly separated out from instance methods.
In your case you would be calling...
[NSUserDefaults resetStandardUserDefaults]

Hey all...
Just a quick question about the NSUserDefaults object.
I have a UserDefault variable which is a singleton set in the
header:
NSUserDefaults * preferenceData;
Now, when I try to reset the preferences [ through a button on
the interface ] using the following code:
- ( void ) resetPreferences
{
NSLog(@"reset preferences - this is not working !!!");
[ preferenceData resetStandardUserDefaults ];
resetStandardUserDefaults is a Class method, but here you are
calling it against an instance that I assume you've gotten earlier...
[ self setDefaultPreferences ];
}
Where setDefaultPreferences is a method that sets up the default
prefs.
This code is returning the error:
NSUserDefaults may not respond to -resetStandardUserDefaults?
Any idea what im doing wrong?
I would have thought this would have worked scenes its in the
documentation!?
Cheers
