Basically my setup is this. I have a many-to-many relationship in Core Data where a student entity can have multiple courses, and a course entity can have multiple students. My problem is in trying to figure out how to bind this relationship to the UI in Interface Builder.

I want to be able to add courses to a course array controller, then have those courses displayed in a popup menu in a NSTableView in the Edit Student window where you can add courses to a student.

This is what I have so far: http://vimeo.com/10671726

It's probably easier to understand from the video.

Thanks

I'm a complete newbie when it comes to iOS programming and much less Core Data. It's rather non-intuitive for me, as I really came into my own with programming with MATLAB, which I guess is more of a 'scripting' language. At any rate, my problem is that I had no idea what I had to do to create a… >>> More
