How to inherit from NSDictionary?

by

NSDictionary is a class cluster. This means that the value returned from its init methods is not strictly an NSDictionary, but a subclass that implements the actual functionality. In almost every case, it is better to give your class an NSDictionary as an instance variable or to simply define a category on NSDictionary.
