iOS Open Source : Facebook Three20
Three20 is an open source project that is the brainchild of Joe Hewitt. Joe is the man behind the original Facebook application for the iPhone.
This library is an expansive collection of classes, primarily GUI related, including a flexible photoviewer (which displays local and remote images), table viewcontrollers that load content from the Internet, and URL-based navigation, among others.
Three20 includes a nice demo application that exercises many of the features of the library.

Hi,
Thanks for sharing. This open source library looks cool on paper but for it is lacking documentation the last time I checked for it. This is a big downer for beginner iOS devs.

I agree, working with Three20 can be a challenge up front. It takes time to wrap one’s brain around how the api’s are structured and documentation could be better. I found that looking into the source code was often helpful to understand the methods. Also, the demo app included is very helpful to see how things work.
Although the learning curve can be steep, hopefully the time spent is a worthwhile tradeoff in having some pretty solid code and features available.
