Controller classes are very useful. It is in the class that you can link your interface widgets to the great coding you have done in other classes.
To create a controller class, go into Interface Builder. Click on the “Classes” tab of the “MainMenu.nib” window. Find NSObject and select it. Now hit the return key. This will create a subclass of NSObject. Name this whatever name you want to give your controller class. To be truely unique you might want to call it MyController.
