Talks

Introduction to Objective-C categories and key/value coding by Michael Raber

Michael has come to love some of the cool features of Objective-C that you might not discover while learning iOS and Mac programming. Categories can be used to add methods to classes without subclassing and key/value coding can be used to set and retrieve property values.

Michael will introduce the topics and show some example use cases. If you have used categories please post your favorites to share here:

RestKit by Corey Floyd

Per their website: RestKit is an Objective-C framework for iOS that aims to make interacting with RESTful web services simple, fast and fun.

Corey will walk us through how he is using RestKit in his latest iOS project.

You will leave with an unbearable urge to test your applications, and your users will thank you!
