InterfaceBuilder - UIViewController subclass not recognized as subclass

Question

I\'m working on a simple iPhone app.

I have 1 UINavigationController and 2 subclasses of UIViewController.

I have a MainWindow.xib file, a PersonListView.xib

Answer 1

I got the same mistake.

The problem is, that you didn't set the target of PersonListViewController.m.

Go to info of PersonListViewController.m, select targets section and make sure that the target of your app is checked.
