TreeView in iOS application

Question

I'll develop a iOS application for ipad.

I need to represent data in a tree, with (+) for expand element and (-) for shrinking of subelements, and in front of each node there is a button, how can I do it?

Thanks

The Apple sample project might inspire you a little. Actually all you need to do is to change the data model and the cell/header views appearance (and you might want to remove UITapGestureRecognizer from the header views using only the button).
