Displaying Your Object Data

After managed objects have been fetched, accessing and displaying data from them is straightforward. For any managed object, using the key-value approach will work to retrieve attribute values. As an example, refer to the configureCell:atIndexPath method in ICFFriendsViewController in the sample app. This code will populate the table cell’s text label and detail text label.
