I posted a cheat sheet for beginners to Objective-C 2.0 some time ago that you may have checked out. Now the reason that I created this cheat sheet is because I know there are alot of developers out there with an understanding of Java, C++ or C# who would like to dive into iPhone development, but don’t have the time to go through an entire Objective-C 2.0 book. So if you’re in this boat this is something you might want to check out.
Now, this is not meant to teach you everything you need to know to program Objective-C 2.0, nor is it meant to teach you all the precise technical details of Objective-C 2.0. The goal of this cheat sheet is simple, I created this so that you can take Objective-C 2.0 examples already out there, go through those examples, and when you run into something that you don’t understand you can look at the cheat sheet, and hopefully get an understanding of what’s going on.
I’ve updated the cheat sheet now and added a couple of things, so check it out if you’re getting into Objective-C 2.0.
If scrib’d is going slowly you can download the Cheat Sheet here: Objective-C 2.0 Cheat Sheet
Also, you can check out this video I made some time ago for the original cheat sheet where I briefly explain most of the topics on the sheet. Sorry if the quality isn’t the best, I’m still trying to get better at videos and don’t forget it’s free!
Best of luck, and I hope this helps those of you who are new to Objective-C 2.0.
