objective c - NSTreeController: how do I find the parent of a node? -

-

i'm looking similar method to: nsoutlineview parentforitem: nstreecontroller.

i need know parent of node in tree.

nodes in nstreecontroller instances of nstreenode, , nstreenode has read-only parentnode property - use that.

the short snippet below gets parent node of first node in tree-controller's selectednodes array:

let selectednode = tree.selectednodes.first! as! nstreenode let parentofselectednode = selectednode.parentnode!
