_OBJC_CLASS _ $ _ - character not found error

Question

I am creating a new application for the iPad, starting with the UISplitView application that works correctly, in the new application I get this error:

"_OBJC_CLASS_$_ConcertListController", referenced from:
objc-class-ref-to-ConcertListController in RootViewController.o
ld: symbol(s) not found
collect2: ld returned 1 exit status

What does it mean? How can i decide?

Answer 1

Apparently you need to bind any structure that ConcertListController is involved in. Try to go to the project window, right-click on the frameworks and select add existing infrastructure .... you should find the structure, including ConcertListController.

Answer 2
