Summary

Want to write iOS apps or desktop Mac applications? This introduction to programming and the Objective-C language is your first step on the journey from someone who uses apps to someone who writes them.

Based on Big Nerd Ranch's popular Objective-C Bootcamp, Objective-C Programming: The Big Nerd Ranch Guide covers C, Objective-C, and the common programming idioms that enable developers to make the most of Apple technologies. Compatible with Xcode 5, iOS 7, and OS X Mavericks (10.9), this guide features short chapters and an engaging style to keep you motivated and moving forward. At the same time, it encourages you to think critically as a programmer.

Here are some of the topics covered:

Using Xcode, Apple's documentation, and other tools Programming basics: variables, loops, functions, etc. Objects, classes, methods, and messages Pointers, addresses, and memory management with ARC Properties and Key-Value Coding (KVC) Class extensions Categories Classes from the Foundation framework Blocks Delegation, target-action, and notification design patterns Key-Value Observing (KVO) Runtime basics

Author Notes

Aaron Hillegass, a former employee at NeXT and Apple, has nearly two decades experience programming and teaching Objective-C, Cocoa, and, more recently, iOS. Aaron is the author of Cocoa Programming for Mac OS X and co-author of iOS Programming: The Big Nerd Ranch Guide. In 2001, Aaron founded Big Nerd Ranch and began developing intensive courses that teach-programming in a focused, distraction-free environment.
Mikey Ward is a senior iOS and Cocoa instructor at Big Nerd Ranch, Since discovering QuickBASIC in the late 80's, he has enjoyed bossing computers around and now enjoys showing others how to do the same. Mikey also convenes the Atlanta chapter of CocoaHeads, a worldwide group devoted to discussion of Apple's frameworks for writing Mac and iOS applications.
