Objective-C Cheat Sheet and Quick Reference

Objective-C Cheat Sheet and Quick Reference Now Available!

Update 9/28/12: Fully updated for ARC and new features in Xcode 4.4+ like auto-synthesis and literal syntax.

Recently I taught an offering of iOS101 at 360iDev, which is a 1-2 day workshop on beginning iOS programming.

In the workshop, I like to cover the basics of Objective-C, since those new to iOS programming are usually also new to Objective-C.

In past offerings of iOS101, a common request was “please make an Objective-C cheat sheet for the workshop!”

Well, your wish is my command – keep reading to download the official raywenderlich.com Objective-C cheatsheet! :]

Show Me The Cheat Sheet!

Without further ado, here is the download link:

Objective-C Cheatsheet and Quick Reference v1.2

It summarizes the most important Objective-C syntax on one page to get you up to speed quickly, including:

• Types and variables
• Creating and using classes
• Defining and implementing methods
• Defining and using properties
• Creating custom initializers
• Handy methods in NSArray/NSString

Feel free to print out a copy or send to a friend who’s learning Objective-C! :]

Also, huge thanks to everyone who attended iOS101. I really enjoyed meeting you guys and hope to see some of your apps in the App Store! :]
