Open-source frameworks/projects for iPhone platform

Question

I'm looking for a collection of open-source frameworks/projects for the iPhone platform.

I've found quite a few good frameworks and resources. Such as ASIHTTPRequest, DrawKit, and Cocos2D just to name a few.

I'm just curious about the minor, or unknown frameworks that have yet surfaced or that I'm unaware of. Do any of you know of frameworks that are not mentioned in the following link?

Some of the frameworks that I've found and utilize in some of my iPhone applications can be found here (list of iPhone frameworks).

I'm not limiting the scope or type of frameworks/projects all are welcome.

Answer 1

This is a pretty cool library:

"ASIHTTPRequest is an easy to use wrapper around the CFNetwork API that makes some of the more tedious aspects of communicating with web servers easier. It is written in Objective-C and works in both Mac OS X and iPhone applications." - http://allseeing-i.com/ASIHTTPRequest/
