Detailed Description

For analytic compatability, child classes overwriting -viewWillAppear: and -viewWillDisappear should remember to call super.

---

Member Function Documentation

- (UIViewController *) detailControllerForObject:

(id)

object

If the subclass does not implement this or returns nil, The infinite scroll controller does not do anything when a cell is selected. Otherwise, it pushes this controller onto the stack.

- (void) reloadTableData

Call this instead of [self.tableView reloadData];

- (UITableViewCell *) tableView:		(UITableView *)	tableView
cellForRowAtIndexPath:		(NSIndexPath *)	indexPath
withObject:		(id)	object

To be overridden by subclasses

- (UITableViewCell *) tableView:		(UITableView *)	tableView
loadingCellForRowAtIndexPath:		(NSIndexPath *)	indexPath

Reasonable default

Member Data Documentation

- (BOOL) _showItems [protected]

It is sometimes desired to not show any items, like For search controllers when there are no search terms / empty search query

---

Property Documentation

- (NSInteger) maxItems [read, write, assign]

Can be used to limit the number of items, even if the datasource contains more than the maxItems

- (NSInteger) pageSize [read, write, assign]

This sets the number of objects to load at a time. Defaults to 10. However, the first page of records is loaded by object source, so the first page of results is configured elsewhere

- (NSInteger) preloadOffset [read, write, assign]

The infinite scroller will start loading the next page at when the table view loads the cell at this offset from the last cell. Defaults to 0.
