Change "Controller Key" list for bindings in IB Inspector

I have next question:

I create own Controller ( myController:NSObjectController ) and it has own attributes, for example NSSt开发者_如何转开发ring* title;

Now I want to bind this attribute to some text field. Can I made that attribute 'title' display in 'Controller Key' menu of inspector binding window in IB; (There where 'selection', 'canADD' and else)

Dont worry about access to this attribute, I want just add it in to list

I think what you want to do is to:

• drag an NSObjectController from the Library palette
• connect its "content" outlet to the instance of your NSObject
• add "title" to the NSObjectController's list of "Keys"
• then use the "title" attribute of your NSObjectController in your text field bindings

I hope this helps.
