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