RKTableController provides a flexible, integrated system for driving iOS table views using the RestKit object mapping engine. Local domain objects can be mapped into table cells within a collection or presented for editing as part of a form. There are three flavors of table controllers available: * Static Tables: RKTableController can be used to render simple static tables that are composed of RKTableItems presented in RKTableSections. Table items can quickly be built and added to a table without a backing model or can have content object mapped into them for presentation. * Network Tables: RKTableController can also render a table with the results of a network load. The typical use case here is to have RestKit retrieve a JSON/XML payload from your remote system and then render the content into a table. * Core Data Tables: RKFetchedResultsTableController can efficiently drive a table view using objects pulled from a Core Data managed object context. Typical use-cases here are for the presentation of large collections that are pulled from a remote system, offering offline access, or speeding up a UI by using Core Data as a fast local cache. RKTableController supports a number of bells and whistles including integrated searching/filtering and pull to refresh.
