Therefore I would like to have a persistent C++ object in the ViewController interface. This fails by forbidding the declaration of 'myCppFile' with no type: #import <UIKit/UIKit.h> ...

I'm finishing a small project, an iPhone game. I've been expanding my GameObject class to include powerups and mines. These are physically identical to each other. Late last night I came up with the genius idea of making two subclasses of GameObject. They're each less than a hundred lines long. I also have to do stuff like cast them t...
