How can I get a variable that is static to each subclass, but that is
declared in the super class?


In short, you can't. "static" in C means "within the scope of the
source file". Split your subclasses off into their own files, define
your static variables there, give them accessor methods, and use those
accessors in the superclass.

Alternatively, if this isn't practical for some reason, you might consider using an NSMapTable or similar data structure to store your per-class info, keyed by class.
