This document provides an introduction to developing applications for Mac OS X and iOS using Objective-C, Cocoa, and Cocoa Touch. It discusses the core technologies and frameworks used, including the Objective-C language, Xcode development tools, Foundation and UIKit frameworks, and key concepts like the MVC pattern. It then outlines several example applications of increasing difficulty that developers can build to learn iOS and Mac development.

1. Introduction to Mac OS
X, COCOA Touch, Objective C and
tools

2. Useful Websites
1. http://developer.apple.com
2. http://devforum.apple.com
3. Stackoverflow
4. Above all ask google

3. We shall learn to run our program @
1. iPhone
2. iPad
3. iPod Touch

4. COCOA Touch & SDK
- Started with NEXT STEP
- Almost 25 years old
- Very High Level (TableView, TabView etc)
- Real world implementation of OO design
pattern (Ex: MVC)

5. Tools, Framework, Language
Tools:Xcode Interface Builder
Frameworks: Foundation (ex: String, array, object
etc), UIKit
Language & Runtime: Objective C (Super set of C)

6. About Objective C
-ObjCis a language focused on simplicity and the
elegance of OO design
- Based on ANSI C
- Brings many object oriented principles, but with
a minimal amount of syntax
- can be compared with designs of C, C++ and
Java
