Indroduction:

iPhone Operating System or iOS is an Operating System developed by Apple for its mobile devices. Popularity of iPhone as an application development platform can be judged from the number of applications that exist at Apple App store. There are over 225,000 iPhone applications at the App store. One of the main reasons for its popularity is the strong developer community behind iPhone.

This 4-day program is meant for programmers (amateur and professional, with experience with at least one Object Oriented language) who want to start developing applications for the iPhone platform. This course will start with the very basics and go on to advanced levels with a strong emphasis on practical learning by the way of examples, demos and lab exercises. This course will cover the various iPhone APIs (media, UI, storage, 2D & 3D graphics etc.) that are available with the iOS.

 

Prerequisites:

• Although we don't require participants to know Objective-C, programming experience in an Object Oriented Programming (OOP) language like Java, C++, C# is a must for effective learning during the course.
• We expect the students to have basic understanding of OOP concepts like Inheritance, Polymorphism, interfaces etc.

 

Software

We will be using XCode 3.2.4 Version for example code and lab exercises.

 

Duration

4 days

 

Objectives

• Introduce new comers to iPhone Development Environment i.e XCode, Interface Builder etc.
• Enable programmers to read and write effective Objective-C code.
• Introduce new comers to the different patterns and practices used by Apple for application development.
