Three20 is an Objective-C library for developing iOS applications.
The library is open-source, and very popular — it’s used by app store giants such as Pulse, Meetup.com, Facebook and others.
Three20 is regularly extended by the community, with free extensions available for any taste.
Three20′s functionality is outstanding and, enhanced by the powerful view controllers employed by this framework, makes for a surprisingly solid, and reliable coding environment.
