ios inheritance header superclass

I'm getting this error: "Cannot find interface declaration for 'BaseViewController', superclass of 'ViewController'. Here's the situation:

AppDelegate:

  • Subclass of NSObject

  • In the header file:

    #include UIApplicationDelegate

BaseViewController

  • Subclass of UIViewController

  • In the header file:

    #import "AppDelegate.h"

ViewController

  • Subclass of BaseViewController

    #import "BaseViewController.h"

The error doesn't make sense, as BaseViewController is imported in ViewController's header file. What is the problem here?

Also check for infinite loops in your import statements
