I will develop an iOS app for ipad.
I need to represent data in a tree, with (+) to expand an element and (-) to shrink sub-elements, and there is a button in front of each node, how can I do this?
thank
Apple's project might inspire you a little. In fact, all you have to do is change the data model and the appearance of the cells / headers (and you can remove UITapGestureRecognizer from the headers using only a button).
