My suspicion would be: not yet. Cocoa hasn't been out very long at all (if you conveniently forget about NeXT, as most people did).
Besides, a real degree would focus more on general programming concepts than on the specifics of Cocoa, and that's exactly what I'd recommend. If you want a course which covers similar programming style, find one that does Java - ObjC and Java are quite close, in all but syntax.
