Creative App Development, Part 1: Objective-C and Cocoa fundamentals
Note: this is a 3-part series. We strongly recommend signing up for all three (and you'll receive a discount on this page if you do!) but if you are interested in only one or two of the topics, or are unable to attend one of the sessions, then you're free to sign up for only the workshops you need. Just make sure you've got a good handle on the material presented in the workshops you missed!
You've just been struck with a bolt of inspiration for a "killer app" that will certainly make you millions on the App Store. Or maybe you have an idea for an interactive art project that will use a customized downloadable app. Now, if only you could implement your genius idea...
By learning a single set of skills, you open the door to creating your own native iOS apps and desktop Mac applications. In just a few lessons, you will pick up the basics of writing and compiling your code in Apple’s development environment, XCode, language basics in Objective-C, and navigating the Cocoa framework.
By the end of the workshop, students will be able to use the XCode environment to code, test and build simple applications in Obj-C and Cocoa for iOS and the Mac. We will also examine how to continue exploring the Cocoa framework, and use other external frameworks to easily extend the functionality of our apps.
Finally, by the last session, we'll move on from Objective-C to do a little bit of overview and integration of Apple's new Swift programming language. Be the first one of your friends to code in the hip new style!
In this Session: Objective-C and Cocoa fundamentals
Learn the fundamentals of using Cocoa within the Objective-C context. Brief coverage of programming basics in Obj-C, including variables, loops, functions, objects, methods, and object messaging. Xcode introduction, introduction to Foundation framework and classes, memory management using ARC, using properties. We will create a Foundation tool for the desktop environment that incorporates classes to be reused in later sessions.
What, if any, prerequisite knowledge should students have?
Objective-C and Cocoa are probably not the best first programming languages, but this workshop will not require any previous technical knowledge of other languages or environments. It would probably be a good idea to be familiar with some basic programming concepts, like using functions and variables, etc.
What equipment should students bring?
A Mac computer with XCode installed (freely available from the Mac App Store, see https://developer.apple.com/xcode/downloads/). Don't forget to download and install XCode before coming to class, as it's a big file to download! Note that this means that your laptop should meet the system requirements for running XCode and the current version of the SDK. The latest OS will definitely be preferable. If you don't have a Mac, contact email@example.com, and we may be able to get you a loaner with the software pre-installed.
