I have a TabBarControlled view navigation and i want to display a UIScrollView in one of the Tabs, but whenever i click on this tab the error-code:

...this class is not key value coding-compliant for the key...

appears.

My code: Code:

#import <UIKit/UIKit.h>


@interface BillViewController : UIViewController <UIScrollViewDelegate> {
 IBOutlet UIScrollView *olta;
}

@property (nonatomic,retain) IBOutlet UIScrollView *olta;

@end

My code has a IBOutlet UIScrollView and it is connected to the IB. My class also implements the desired protocol and the delegate is connected to the BillViewController-class.

thanks
