Objective-C Cheat Sheet and Quick Reference Now Available!

Update 10/13/13: Fully updated for Xcode 5 and current best practices.

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

We periodically teach a workshop called iOS 101, which is a 1-2 day crash course on beginning iOS programming.

In the workshop, we 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 iOS 101, a common request was “please make an Objective-C cheat sheet for the workshop!”

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

Without further ado, here is the download link:

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