In this screencast I’ll show you how to power an NSTableView using code. I’m referencing this article for code snippets and details: http://pinkstone.co.uk/how-to-populate-an-nstableview-in-code/
I’ve also made a “no-code” version on how to populate an NSTableView using an Array Controler and Cocoa Bindings here: http://pinkstone.co.uk/how-to-bind-an-nsarraycontroller-to-an-nstableview/
Enjoy!
