It's 2013, why aren't you using properties in all of your classes? And you should be prefixing your classes to avoid namespace collisions.
It's snarky comments like these that prevent people from confidently sharing their code.
Got a helpful comment to make? Great! How about sharing it minus the veiled insults next time?
OP doesn't owe you clean code. Don't like the code? Don't use it.
Or better yet, contribute a patch/PR. The OP's intention in sharing it was to get contributors: https://news.ycombinator.com/item?id=5678490
And prefixing classes is not for "clean code", it's to avoid namespace collisions which is a valid and common issue in Objective-C development.
