CRFPagingController provides "infinite scrolling" functionality to UITableViews by implementing the UITableViewDataSource protocol and forwarding methods to a "real" data source. This allows one to easily enable table view paging by simply placing this controller between the data source and table view.

Implement the CRFPagingControllerDelegate protocol (in addition to the UITableView delegate and dataSource):

@interface MyDataSource : NSObject <CRFPagingControllerDelegate, UITableViewDelegate, UITableViewDataSource>

...

@end

Instantiate the CRFPagingController:

self.pagingController = [[CRFPagingController alloc] init];

Set the delegate, tableViewDataSource and tableViewDelegate properties:

self.pagingController.delegate = self.dataSource;
self.pagingController.tableViewDataSource = self.dataSource;
self.pagingController.tableViewDelegate = self.dataSource;

Set the dataSource and delegate of your UITableView to the CRFPagingController instance.

self.mainViewController.tableView.dataSource = self.pagingController;
self.mainViewController.tableView.delegate = self.pagingController;

Configure the CRFPagingController:

self.pagingController.buffer = 5;

IMPORTANT: You MUST set the tableViewDataSource and tableViewDelegate properties of this class BEFORE you set the dataSource and delegate properties of the UITableView.
