Editable Grouped UITableView

My designer wants me to implement a开发者_如何转开发n editable grouped tableview with functionality similar to what you see with 'ABNewPersonViewController' in the Contacts application where there are segmented table areas with add/delete buttons, etc.

Is this a standard way to edit information that is viewed in grouped tables? If so, are there any good examples of this out there that don't involve the AddressBook UI Framework?

Thanks!

The design pattern using add/delete buttons on table views shows up in a couple of sample code projects from Apple that I've used. That's a good place to start.

As for "is this a standard way", I guess the answer is "yes and no". Yes because Apple certainly does it this way, but no because they don't always use this design pattern in all their table-based apps.
