The Essence of Cocoa

This chapter covers the most common object-oriented design pattern used in Cocoa and shows how that paradigm is applied to application development. A design pattern is a template for a design that solves a general, recurring problem in a particular context. If you have done object-oriented design before, you may be wondering how that model fits into the world of Cocoa. This tutorial will help you understand what Cocoa is as an object-oriented framework. If you’ve done only procedural programming before, don’t worry. This tutorial also teaches the basics of the object-oriented programming. You will learn the MVC design pattern, which is a very common practice used by application developers.
