How to access IBOutlets declared in superclass?

Question

I'm currently refactoring a couple of view controllers that share a few IBOutlets and IBAction methods. I moved the outlet declarations and the IBAction method into a superclass, cutting these out of the subclasses.

Now, when I open up Interface Builder, I find that I can't see the outlets or actions declared in the superclass. The connections still exist, as I'd wired them up before the refactoring, but they're grayed out. (It's important to note that the connections also WORK, as my action fires on a button press, and my outlets are modified properly.)

The question is, how can I get interface builder to recognize outlets from a superclass? Is this possible, and, if not, what do you all recommend?

(Just for fun, here's my superclass header file:)

@interface TFMainViewController : UIViewController {
    UIImageView *logoImage, *thinkfunImage;
    UIButton *buyFullButton;        
}

@property (nonatomic, retain) IBOutlet UIImageView *logoImage, *thinkfunImage;
@property (nonatomic, retain) IBOutlet UIButton *buyFullButton;

-(IBAction) buyFullVersion;

@end

EDIT: in case anyone's wondering, I'm using Xcode and IB 3.2.5, with the iOS 4.2 SDK.

Answer 1

I didn't realize it was even possible to connect to superclasses in interface builder until about an hour ago. Since this was the only question I could find regarding how to do this, I'll add my answer, even though this question is old. My answer is with regard to Xcode 4, not Xcode 3.

As far as I can tell, you can't connect to outlets in a superclass using the assistant editor, but you can do it by clicking on "File's Owner" in IB. That should show all the outlets in Utilities->Connections Inspector. You can then Ctrl+Click on the outlet in the inspector (click on the '+' sign), and drag it over to your view in IB.
