Presence is a Twitter client originally started as an assignment for CS193P. It has since moved away from strictly being based on those assignments to explore other aspects of iPhone Development.
Presence depends on the fmdb sqlite3 wrapper written by Gus Mueller and json-framework by Stig Brautaset. To that end, I have forked the github repositories for those projects and included them as git submodules. The steps to get up and running are:
git clone --recursive git://github.com/adamvduke/Presence.git cd Presence git submodule init git submodule update
The submodules will be their own git repositories in the directories Presence/External/fmdb and Presence/External/JSON
