Basic Object-Oriented Concepts

Basic Object-Oriented Concepts

 

Object-oriented (or OO) design involves identifying and defining objects
that represent information together with behavior, or how this information
is manipulated, and designing the interactions (known as collaborations)
among objects so that the application can do what it needs to do. What an
object does is defined by a template called its class. How an object is used is
described by its type.
If that sentence makes perfect sense, you’re probably a veteran OO programmer
in a language like Java or C++. You have my permission to skip to Chapter 3 and
go directly to learning about Objective-C.
If you’re coming to iOS without any programming experience, don’t fret. This
chapter is great for those starting to learn OO design concepts. Just read on,
and I’ll show you how.
