Objective-C
iOS applications are written in the Objective-C language using the Cocoa Touch library.
Objective-C is a simple extension of the C language, and Cocoa Touch is a collection of
Objective-C classes. This topic assumes you know some C and understand the ideas of
object-oriented programming. If C or object-oriented programming makes you feel uneasy,
we recommend starting with
Objective-C Programming: The Big Nerd Ranch Guide
.
In this chapter, you will learn the basics of Objective-C and create an application called
RandomPossessions
. Even if you are familiar with Objective-C, you should still go through
this chapter to create the
BNRItem
class that you will use later in this topic.
