I have a document based cocoa application with an item in the application menu hooked up to an IBAction . Clicking the item needs to perform a task that uses an IBOutlet in the main nib file which is using another class, MyDocument . Creating 2 objects of the same class, one in each nib seems to not be working. How can I access the outlet?

It sounds like this action is something that works on the current document, then it should be implemented by the document. In this case have

How do I do that? I can't access the IBOutlet from the second view. Is there something that I have to do to the IBOutlet to make it public etc? You can use NSNotificationCenter for that.

How do I access IBOutlets that have been created in another class? For example, if I have an IBOutlet in Class A how can I access in Class B ? If I can not access IBOutlets from other classes what is a work-around?
