2Objective-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 book 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 book.
