I originally wrote that sheet sheet (nearly 3 years ago now!) to help out some developers who were new to Objective-C, but familiar with Objective-C. On that cheat sheet you’ll find some basic syntax examples, and it was meant to help one quickly get through the more basic iOS examples provided by Apple.
This new cheat sheet has a lot more to it providing more a complete listing of @ compiler directives. It might be a bit too wordy for purists to call it a cheat sheet, but it fits on 1 page!
The cheat sheet is built from Steffen Itterheim’s excellent post listing Objective-C 2.0 @compiler directives with short direct explanations, and straightforward examples that you can find here.
It’s a complete listing including a couple of keywords from the iOS 5 developer SDK.
I’ve taken Steffen’s large post which filled up close to two pages of text, and put it all into one page reworked each description making it fit on one page, keeping the examples in tact, and keeping the font a readable size.

Hopefully this will help you get started with Objective-C quicker or pass that Objective-C exam
