    <p>I am trying to create a table view which uses two types of cells - default and subtitle. </p> <p>I tried to use a single reusable cell (<code>*cell</code>) which seemed to work fine until I got to the bottom cell which was off screen - when this came into view it was a duplicate of the first visible cell. </p> <p>I thought that I could try to add a second type of cell (<code>*cellB</code>) and when I did it seemed to solve the problem however it would crash every so often with the following error:</p> <pre><code>Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'UITableView dataSource must return a cell from tableView:cellForRowAtIndexPath:' </code></pre> <p>I know that I am doing something wrong and I am pretty sure I am not implementing the reusable cells properly but after several days of frustration I would really appreciate some advice. </p> <p>P.S. I have searched many previous posts but none seem to cover the issue of using two types of cells on the same table.</p> <p>Thanks in advance. </p> <pre><code>- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section { return 1; } - (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView { return 5; } - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:@"UITableViewCell"]; UITableViewCell *cellB = [tableView dequeueReusableCellWithIdentifier:@"UITableViewCellB"]; switch (indexPath.section) { case 0: if (cell == nil) { // The only subtitle cell cell = [[UITableViewCell alloc]initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:@"UITableViewCell"]; } [[cell textLabel] setText:title]; [[cell textLabel] setTextColor:[UIColor whiteColor]]; [[cell detailTextLabel] setText:[NSString stringWithFormat:@"Entry: £%@",price]]; [[cell detailTextLabel] setTextColor:[UIColor colorWithWhite:1.0 alpha:.8]]; cell.selectionStyle = UITableViewCellSelectionStyleNone; break; case 1: if (cell == nil) { cell = [[UITableViewCell alloc]initWithStyle:UITableViewCellStyleDefault reuseIdentifier:@"UITableViewCell"]; UIView *cellBackView = [[UIView alloc] initWithFrame:CGRectZero]; cellBackView.backgroundColor = [UIColor colorWithPatternImage: [UIImage imageNamed:@"PhotoFrame.png"]]; cell.backgroundView = cellBackView; } [lImage setFrame:CGRectMake(0, 23, 320, 200)]; [cell.contentView addSubview:lImage]; break; case 2: if (cell == nil) { cell = [[UITableViewCell alloc]initWithStyle:UITableViewCellStyleDefault reuseIdentifier:@"UITableViewCell"]; UIView *cellBackView = [[UIView alloc] initWithFrame:CGRectZero]; cellBackView.backgroundColor = [UIColor colorWithPatternImage: [UIImage imageNamed:@"PaperTop.png"]]; cell.backgroundView = cellBackView; } break; case 3: if (cell == nil) { cell = [[UITableViewCell alloc]initWithStyle:UITableViewCellStyleDefault reuseIdentifier:@"UITableViewCell"]; UIView *cellBackView = [[UIView alloc] initWithFrame:CGRectZero]; cellBackView.backgroundColor = [UIColor colorWithPatternImage: [UIImage imageNamed:@"Paper.png"]]; cell.backgroundView = cellBackView; } break; case 4: // I'm pretty sure this bit is wrong but if I use (cell == nil) the first cell is shown instead if (cellB == nil) { cell = [[UITableViewCell alloc]initWithStyle:UITableViewCellStyleDefault reuseIdentifier:@"UITableViewCellB"]; UIView *cellBackView = [[UIView alloc] initWithFrame:CGRectZero]; cellBackView.backgroundColor = [UIColor colorWithPatternImage: [UIImage imageNamed:@"PaperBottom.png"]]; cell.backgroundView = cellBackView; } break; default: break; } return cell; } </code></pre>

Guidance
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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
