Office Hours is an event that lets hobbyists work next to experienced developers, encourages lots of question asking, pair programming and mentoring. We welcome programmers of all backgrounds and platforms but tend to focus on Mac/iOS.

If you plan to stop by please send a short email to Mike Zornek. Thanks!

You’ll need to use the intercom to get in (#022). If you are having any trouble feel free to call MikeZ’s cell (267-563-0616) and we’ll be sure to get you in.

We usually all chip in and order some pizza and refreshments, so if you can bring a few bucks for that please do.

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:

UIViewController Containment by Matt Thomas

Matt will be doing a talk on UIViewController Containment covering:

• The basic concept behind the “View Controller Pattern” and the difference between “content” and “container” view controllers.
• How iOS 5 formalized the concept of a container view controller.
• The odd dual hierarchies between “View Hierarchies” and “View Controller Hierarchies”.

• How to implement your own container view controller, tips, and pitfalls

About CocoaHeads

PhillyCocoa is a Philadelphia area Mac and iPhone programming group, a chapter of the worldwide CocoaHeads. All skill levels are welcome. The only requirement is an interest in Apple-related technologies and moderate tolerance for geeking out.

We hold our CocoaHeads group meetings on the second Thursday of every month at Indy Hall. A calendar feed can be found on the PhillyCocoa website.

We are always looking for feedback and suggestions on what topics to discuss at our meetings. We have a public writeroom (password is “password”) where we try to keep tabs on what people are interested in hearing about. Feel free to append your own ideas, especially if you are interested in speaking.

Implementing a RFID scanner on iOS by Mike Zornek

Mike recently did a small project to prototype a RFID scanner for iOS. Was a fairly painless process. He’ll demo how it went down and what you should look for if interested.

Talks

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. It combines a clean, simple HTTP request/response API with a powerful object mapping system that reduces the amount of code you need to write to get stuff done.

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

Cocoa Quiz

The quiz show from our canceled holiday meeting has been refactored. We’ll have a little trivia on the code and culture of Apple, awarding software license prizes as we go. Bring your thinking cap.

Sadly, I’m still recuperating from a bad head cold and since I still had some prep work to do for the party plus run the quiz it’s not something I can easily hand off to someone else with late notice.

We’ll have a condensed version of the quiz in the January meeting along with a speaker (TBD).

Thanks for your understanding.
