how to block a superclass method to be called to a subclass

Question

I\'m extending the functionality of a class with a subclass, and I\'m doing some dirty stuff that make superclass methods dangerous (app will hang in a loop) in the context

Answer 1

If you create the methods in your superclass as "private" then the subclass has no possible way of calling them. I'm not familiar with Objective C, but every other object oriented language I've seen has the "private" qualifier.
