How to prevent a sub view from drawing until parent view is selected?

Question

I have a NSTabView with 3 tabs. I want to prevent the subviews of those tab from drawing until it is selected. How would I go about doing this? I have set up a delegate for the NSTabView but am having trouble figuring out which tab is selected.

I had similar problem(i had two views, view1 above view2 and view2's subviews were drawed while a i was dragging view1)
The way out was to make a tmpView,that contained all subviews and make [tmpView setHidden:YES]; if it wasn't an active view, and switch on visibility when view2 became active.

that answers part of it, but how do I detect which tab is detected to determine which view to set hidden/unhidden? – stormbard Jan 10 '13 at 21:26
tabState property of NSTabViewItem can be NSSelectedTab, NSBackgroundTab, or NSPressedTab. – alex Jan 10 '13 at 21:33
that got it, is there a way to prevent drawing until that after the application has finished launching? or how do I pass the ManagedObjectModel and ManagedObjectContext to the tab view? – stormbard Jan 10 '13 at 22:04
