But what happens to the variables within a class method? What is

And what do you call them? :-))
Example:
+ (void)doSomething

NSString *test_string;
There is absolutely nothing different about this variable vs. a
variable declared in an instance method or a variable declared in a C
function.
It is a plain and simple local variable allocated on the stack. It
follows the standard C stack based variable semantics. A quick
Google search or read of K&R will exactly specify the behavior.
