I released SSToolkit awhile ago. It's an open source library for doing common things in iOS. It's the overflow of stuff that I use on a daily basis. It's pretty much everything I've ever written that is iOS related that is reusable, open sourced, and released for free.
I recently received this email from a developer using my framework.

your code is easy to use and the instructions to import it into an Xcode project, on your website, are clear and simple.
Totally made my day. Here's another example.
