Suppose this:
1. Sub is a subclass of Super, hence it has a <#include "Super.h">;
2. Sub defines the method sub;
3. Super defines a method whose code contains the message: [Sub sub].
How can I get Super to know about Sub's sub method? Having a
<#include "Sub.h"> in Super.m causes a compiler error, while <@class
Sub;> tells Super that there's a Sub class, but nothing about its
methods.
Using protocols somehow? But I don't want to implement the sub method
in Super, I just want to let Super know about it.
