FBGraphObjectPickerViewController
This class is no longer available in the most recent version of the SDK.

The FBGraphObjectPickerViewController class is an abstract controller object that manages the user interface for displaying and selecting a collection of graph objects.

Discussion:

When the FBGraphObjectPickerViewController view loads it creates a UITableView object where the graph objects defined by a concrete subclass will be displayed. You can access this view through the tableView property.

The delegate property may be set to an object that conforms to the FBGraphObjectPickerDelegate protocol. The delegate object will receive updates related to object selection and data changes. The delegate can also be used to filter the objects to display in the picker.

Use this if the filter or sort (if applicable) properties change. This may affect the order or display of information.
