## Discussion

Discussion This method is intended for use with cell-based table views, it must not be used with view-based table views. In view-based tables, use target/action to set each item in the view cell. note: This method is optional if your application is using Cocoa bindings for providing data to the table view, otherwise it must be implemented.
