#uitableviewdatasource

A UITableViewDataSource must implement:

tableView:numberOfRowsInSection:

tableView:cellForRowAtIndexPath:

Each row in a UITableView is a UITableViewCell. Each UITableViewCell has a contentView, which holds the content for the cell.

Each TableViewCell has a UITableViewCellStyle which determines the composition of subviews within the contentView.

To map cells to items:

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {     UITableViewCell *cell = [[UITableViewCell alloc]       initWithStyle:UITableViewCellStyleDefault        reuseIdentifier:@"UITableViewCell"];     Record *record = [[itemStore allItems]                                     objectAtIndex:[indexPath row]];     [[cell textLabel] setText:[p description]];

    return cell; } - (NSInteger)tableView(UITableView *)tableView     numberOfRowsInSection:(NSInteger)section {     return [[itemStore allItems] count]; }

A UITableView shows a single column of data, with 1 or more rows:

A UITableView is best accompanied by a UIViewController to handle its appearance on the screen.

A UITableView takes a data source, conforming to UITableViewDataSource, from which to display data.

A UITableView takes a delegate, conforming to UITableViewDelegate, to inform it of events involving itself.

An associated UITableViewController normally acts as view controller, data source, and delegate.

UITableViewController has a view, which is an instance of UITableView. When a UITableViewController creates its view, the dataSource and delegate variables of the UITableView are automatically set to point to the UITableViewController.

The designated initializer of UITableViewController is initWithStyle:, which can be either UITableViewStylePlain or UITableViewStyleGrouped (where the top and bottom rows have rounded corners).
