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