What I meant here are the variables used within the class method. These are unique as opposed to the variables of a method of an object that is instantiated?

There are no special type of variables for class methods (ie. while there are instance variables, there are no class variables). You might think of "static" variables (often used as a substitute for proper class variables), or other variables with a global scope.

But what happens to the variables within a class method? What is their scope?
And what do you call them? :-))



Example:


+ (void)doSomething { NSString *test_string;


//Is this variable unique for all calls to this class method?


return; }



Thanks!
