问题
I have a application with a tab view when the user clicks in the menu for example "client data" I generate a tab programmaticaly. Now I want to subclass the tab view to add a close button for each NSTabviewitem. If you don't have an answer you could help with documentation or sample code

I know this question is ancient, but...
I spent some time trying to add buttons to NSTabViewItems with a custom subclass, and as far as I can tell it's not really possible. NSTabViewItem simply isn't customizable enough to do the job.
My suggestion is to take a look at chromium-tabs or perhaps PSMTabBarControl; they have a different appearance than standard NSTabViewItems, but provide out-of-the-box functionality for icons and close buttons.
