Referencing Outlet vs. Outlet

http://www.iphonedevsdk.com/forum/iphone-sdk-development/11838-referencing-outlet-vs-outlet.html

An outlet is an IBOutlet. I'll assume you know what that is.

The term referencing outlet means an outlet in another object that references, or points to, the current object.

As an example, say you have a nib that has a File's Owner and a UITableView in it, among other things. In order for a tableview to work it has a datasource and delegate, which are outlets and can be connected in IB. From the standpoint of the tableview the datasource and delegate are outlets. From the standpoint of the File's Owner the datasource and delegate in the tableview are referencing outlets.
