Parameters:

  • item (defaults to: nil) —

    this can be a tree-like item (View, ViewController, CALayer, Menu) or an integer, in which case it will select that window. Defalt is to display the keyWindow

  • selector (defaults to: nil) —

    If you pass an unsupported object to tree, you will need to pass a selector as well - this method should return an array of items which are passed recursively to tree
