if your using #include instead of import then use this technique to minimize duplicates: at the begining of your interface (actually right before it) do check for a definition and if not defined then define it and proceed to define your interface. here is an example:

 #ifndef __NetworkOptionsViewController__H // check if this has every been imported before
 #define __NetworkOptionsViewController__H


#import "blahblah.h"

 @interface NetworkOptionsViewController : UITableViewController

 {

NSMutableArray* somevariable1;
int somevariable2;


 }
 @end



 #endif

-- Onto your specific trouble which i have encoutered before, i got this error because the file path to my class was wrong. I checked file inspector and my class file path was not defined in Classes folder yet in the IDE it was. I deleted them and copied them over again.
