Objective-C for Beginners

iOS fundamentals for mere mortals.

Whether you're new to object-oriented programming or just new to the Objective-C programming language, this course will get you up to speed fast. Learn the fundamentals of Objective-C while gaining an understanding of its relationship with the ANSI C language. You'll come away with the background you need to start learning the specifics of app development for the iOS and OS X platforms.

Smaller class size = better learning.

Learning a complex new technology in a large group setting can sometimes be an intimidating experience. Why risk missing out on important details? Our smaller class size will allow you to feel comfortable asking whatever questions you like. It'll also help ensure you get all the individual attention you need during lab exercises.

Please feel free to reserve one of the available Macintosh computers in our state-of-the art classroom, or bring your own MacBook Air or MacBook Pro if you prefer.


Updated for iOS 7


Duration

2 days.

Objectives

This fast-paced, two-day intensive will get you off to a quick start coding in Objective-C. There's plenty of lab time to allow you to learn by doing. And our exercises are designed to reinforce key concepts in a way that will help you gain proficiency fast. Between lecture sessions and hands-on labs you'll get a first-hand introduction to fundamentals of the ANSI C programming language, and object-oriented programming with Objective-C classes, objects, methods, instance variables, messages, and more.

You'll also get a peek under the hood to gain insight into how Objective-C actually works under the covers. That'll come in handy in many situations: whether you're trying to learn to use a new feature, find a tricky bug, or design a new component. You'll also learn tips and techniques for taking advantage of numerous powerful, built-in features of the Objective-C language and the iOS SDK's libraries and frameworks.
