Understanding the Objective-C programming language is critical to becoming a successful iPhone developer. This class is designed to teach you a solid foundation in Objective-C 2.0 from the ground up.

This course does not require or assume any background in Objective-C, C, C++ or Object Oriented Programming (OOP) in general. Stephen Kochan will lead you into the Objective-C 2.0 world step by step. You will learn how to enter, develop, and debug your programs under Mac OS X using the Xcode development tool.

This class teaches the Foundation framework in Objective-C and also teaches you how to write your first iPhone applications. The Foundation framework defines a base layer of Objective-C classes for working with objects such as numbers, strings, arrays, and dictionaries. Understanding the Foundation Framework is critical to becoming a successful iPhone developer.

This course assumes you have a basic working knowledge of Objective-C. Please consider taking our iPhone / iPad Programming Part I: Programming in Objective-C 2.0 class if you don't have this knowledge. Alternatively, very experienced programmers can take the first lecture, which is an Objective-C language review, to quickly get up to speed for the remaining lectures.
