I'm having a very hard time following what you are trying to do, in part
because generic names in code (e.g. "upperClass" and "function") are
hard to keep straight.
You say you are trying to call an instance method. Do you mean you just
want to do something like:
MyUpperClass *upperClass = [[MyUpperClass alloc] init];
[upperClass function:someVariable];
