For more videos on technology, visit our website at http://www.techytube.com. By pavel@techytube, for more from this author visit: http://www.techytube.com/author/pavel The UITableViewDataSource protocol is usually implemented by an ViewController class that mediates the applications data model for a UITableView object. The data source provides the table view object with the information it needs to construct and modify a table view. As a representative of the data model, the data source supplies minimal information about the table views appearance. The table-view objects delegate—an object adopting the UITableViewDelegate protocol—provides that information. In the last video weve discussed about the required methods of the UITableViewDelegate protocol. There are also a couple of optional methods. For example in case of Grouped-Style table-views, we have sections, and each section may have a header and a footer. To specify how many sections a table view should have, we implement the following method: - (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView { return 2; // 2 should be replaced with the number of sections we need } To specify the title of each section in a table view, we implement the following method: - (NSString *)tableView:(UITableView *)tableView titleForHeaderInSection:(NSInteger)section { NSString *titleOfSection; switch (section) { case 0: titleOfSection = @First Section; break; case 1: titleOfSection = @Second Section; // ... and so on, depending how many sections we must have default: titleOfSection = @No Title; break; } return titleOfSection; } For more, please visit Apples online documentation at: http://developer.apple.com/library/ios/#documentation/uikit/reference/UITableViewDataSource_Protocol/Reference/Reference.html$

The data source provides the table view object with the information it needs to construct and modify a table view. As a representative of the data model, the data source supplies minimal information about the table views appearance. The table-view objects delegate—an object adopting the UITableViewDelegate protocol—provides that information. The two required methods of the protocol provide the cells to be displayed by the table-view as well as inform the UITableView, and they should look as below: - (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section { return 3; } - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *CellIdentifier = @Cell; UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier]; if (cell nil) { cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier]; } return cell; } We can also set the cells properties, for example: cell.textLabel.text = [NSString stringWithFormat:@Cell %d, indexPath.row]; Many methods take NSIndexPath objects as parameters. UITableView declares a category on NSIndexPath that enables you to get the represented row index (row property) and section index (section property), and to construct an index path from a given row index and section index (indexPathForRow:inSection: class method). (The first index in each index path identifies the section and the next identifies the row.)
