Hello I am building forms over and over in iPhone and iPad apps:
I can't imagine I'm the only one doing this. Is there a mature framework or something that can drop in and use? Could you please comment on how you use this library with designs other than vanilla UITableViews with your own colors etc.?
Take a look at IBAForms - an open source project from from Itty Bitty Apps. I haven't used it yet myself, however I believe it does most of what you want, except for validation. Here is the github page: IBA Forms
It hasn't been maintained in a while, but if you're looking for a forms library - it's mature and works. At the very least, it could be the starting point for something you take further.
Update: There is also Chris Miles' EZForm library, which is very nice.
Update #2: Have also started checking out QuickDialog, which seems to be very popular.
Update #3: Nick Lockwood has created one called FXForms
Update #4: Martin Barreto has created one called XLForm
