Is three20 still actively being developed? From the three20.info site, I see no new features/UI ele开发者_运维问答ments since earlier this year when I looked into it.
Besides three20, is there another good framework out there?
As far as i know, Three20 is only maintained by community (bug fixes). Jeff left the project and decided to clean up that mess & provide solid documentation.
He recently started a new project on github called Nimbus, his plan is to port all features of Three20 to Nimbus without the problems we face today with Three20.
I haven't given up on three20 yet. It's a good framework and it saves me hours of work. I'm submitting bug fixes and small improvements to the framework from time to time and I see some activity in github. (not as much as it used to be)
I tried using nimbus, and I was really impressed with the documentation and existing classes. However, note that the developer went to work in CA and said he'll contribute less to his new framework.
The three20.info site is not maintained, but you can download the latest version from github.com/facebook/three20.
