Can't create IBOutlet for UIBarButtonItem in a UIViewController

Question

I'm trying to create an IBoutlet from a UIBarButtonItem to a UIViewController, but when ctrl+clicking and dragging to the controller, I see no indicator whatsoever, and thus it's impossible to create it. Not sure what I'm doing wrong.

Here's the screenshot, in case it could clear something up:

Thanks a lot in advance!

EDIT: I also tried to create the IBOutlet manually with @property (weak,nonatomic) IBOutlet UIBarButtonItem *barButtonItem; and then ctrl+clicking and dragging, but same result.

Answer 1

I was able to create a UIBarButtonItem IBOutlet

@property (nonatomic, weak) IBOutlet UIBarButtonItem *cameraLibraryToggleButton;

Answer 2

I do not think you can create an IBOutlet for a UIBarButtonItem ... Instead create a IBOutlet for your UIToolbar and give your UIBarButtonItem a tag of 1. Next use this code:

 for(UIBarButtonItem *button in self.toolBar.items)
 {
       if(button.tag == 1)
       {
            UIBarButtonItem *newButton = button; //Your UIBarButton   
            //Do whatever you want with it.
       }
 }
