Inline Editing within UITableViewCell?

I’m trying to build an app that uses UITableView and UITableView Cell.

I want users to tap an Add button to add an item to the TableView without calling up a new window (like this book does) or an alert pop-up. I also want users to tap a cell to edit its value and then save it.

I’m struggling to find the best way to do this. Based on what Apple documents about UITableViewCell, it doesn’t seem possible.

Is there a better approach?

You can add a button in a navigation bar which does that without calling up a new window. You can edit a TableView Cell, and if you search in the documentation, you will find how to make a customized UITableViewCell with all you want inside!!!
