I an objective-c architecture question:
I have class B that inherits from class A. I now need to make a class
C. It turns out that 90% of the functionality (including class
variables) would be shared between B's implementation (its subclass
implementation) and C's implementation. In C++, I would break out that
functionality, creating class D. Class B would inherit from A AND D,
while C would inherit from D. I know that objective-c doesn't have
multiple inheritance, so I was wondering how similar class
functionality is handled there. Note that I DO have class variables
(instance variables), which precludes using categories to support this.
