I have a set of entities:
Range name - String Area name - String Language name - String descriptiveText - String
I would like to display these on the same level of an NSOutlineView. So, it would display something like
Ranges name name Areas name name Languages name name Other Thing1 Thing2
The Other list is a non Core Data list. Taking a look around it seems like the best way to do this is with an NSTreeController but I’m not sure how to setup the controller to use multiple entities, and non-entity items, at one time.
Are there any documents or blogs that discuss how to tackle this?
