Ok, I'm trying to learn Objective C in a day.  Does anyone know the language?
I'm reading through "Object-Oriented Programming and the Objective C
Language" a OpenStep book that Apple now sells.  The thing that is
stumping me a little bit is the differance between a class method and
a instance method, maybe I'm just forgetting my OOP terminology, but
Objective C makes a definable differance between the two.  So you
have an interface:

@interface MyClass : Object
{
  int instance_var;
}

+ foobarClassMethod;
- (BOOL) foobarInstanceMethod;
@end

If you don't have a return type in () specified it returns the id class
type.  All classes inherit from Object, like in SmallTalk, unless you
want to make a new root class (probably not a good idea), NeXTStep appears
to use NSObject instead of Object which the GNU compilers use.

So how is the class method used differantly than the instance method?
