Undefined Symbols

OC asks:

“I’m doing some Objective-C exercises from a Big Nerd Ranch book, and I’m getting these errors. I’m still pretty lost in terms of how to handle unexpected errors and stuff, so I would appreciate the help.”

I’m going into go into much greater depth here answering this question, because of “teaching a man to fish”, ya’know.

Apple Product Non-Placement

A German TV movie (based on a Katie Forde novel) has a scene where a protagonist views from photos taken with a Canon camera. Though there are several things wrong here that cause Apple buffs to wince.

Zip Snapshot of GIT Repo

The sample apps I am making to accompany bug reports to Apple I generally create with a GIT repo behind them. I’ve gotten used to Xcode already creating a new repo when I start a new project, so why not make use of the GIT Goodness.

But when it then comes to attaching this project to a Radar I want the ZIP to be a small as possible. GIT provides several methods to achieve that.

International Internship Fail

Unhappy Intern

When I read this article about Unpaid Internships back in May I got a feeling that I should try to do something about this injustice. In fact I know of several companies here in Austria who are also receiving cheap labor from college students who just need a place to do some “research” for a paper or degree.

Two years ago, for WWDC 2011, I researched how to get 3G data on my iPhone. Last year AT&T tweaked their policies slightly to make it more complicated to use prepaid data with smart phones. Since I got myself a phone with nano SIM (iPhone 5) since then I needed to do something again.

Also 2013 marked the first day when I brought my employee to WWDC and wanted him to have prepaid data as well. In this post I’m summarizing the current state of affairs as of Summer 2013.

I’m a Game Studio!

Until today I had only every tried my hands on a UIKit-based game, a clone of the Wheel of Fortune game show. Unfortunately Sony Entertainment asked Apple to ban this from the app store. So I had to take it offline.

Whenever an independent game developer had a success I would feel jealousy boil up in my stomach. If only I could also make games. But I was too busy mastering Objective-C and Apple’s frameworks (on iOS and Mac) to be able to devote time to learning Cocos2D.

This has entirely changed last week, when Apple announced the new Sprite Kit framework.
