Answer 3

The biggest framework of this kind is Three20. Facebook and many other companies use this. Three20 is geared towards apps that pull data from the web. It helps with common patterns like a photo viewer or table view backed by web data. Another neat feature is that it has stylesheets, similar in concept to CSS.

Having said all that, some people like it and some do not. There was a brief period where apps using it were rejected from the App Store. Overall, the project looks to have improved since then.
