    <p>I am programing a UITableView to behave as an inclusive selection list. My table displays correctly and allows for multiple cells to be selected with check boxes. My problem is that cells which have been selected (cells contain a check mark to the right) loose their selected status when scrolled out of view (cells check mark disappears). I want the selections made to cells in the table to be preserved even if cells are scrolled out of view. Does anyone have any idea what is causing this? </p> <p>Here is my code inside of my TableViewController class: </p> <pre><code>- (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] autorelease]; } NSUInteger row = [indexPath row]; cell.textLabel.text = [widgetTitles_glob objectAtIndex:row]; cell.detailTextLabel.text = @""; cell.textLabel.textColor = [UIColor blackColor]; cell.textLabel.font = [UIFont boldSystemFontOfSize:15]; cell.accessoryType = UITableViewCellAccessoryNone; return cell; </code></pre> <p>}</p> <pre><code>- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { [tableView deselectRowAtIndexPath:[tableView indexPathForSelectedRow] animated:YES]; UITableViewCell *cell = [tableView cellForRowAtIndexPath:indexPath]; if (cell.accessoryType == UITableViewCellAccessoryNone) { cell.accessoryType = UITableViewCellAccessoryCheckmark; // Reflect selection in data model } else if (cell.accessoryType == UITableViewCellAccessoryCheckmark) { cell.accessoryType = UITableViewCellAccessoryNone; // Reflect deselection in data model } </code></pre> <p>}</p> <p>Any help would be very much appreciated. </p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
