    <p>In the following bit of code, I'm setting the table view cell text with a value from the NSMutableArray 'categories' which is a property of my view controller. That works fine.</p> <p>But when I try the exact same code in another method, it crashes (it compiles without errors or warnings). If I change the following line in the didSelectRowAtIndexPath method:</p> <pre><code>NSString *categoryName = [categories objectAtIndex:indexPath.row]; </code></pre> <p>to</p> <pre><code>NSString *categoryName = [[NSString alloc] initWithString:@"test"]; </code></pre> <p>It works... any ideas?</p> <pre><code>// Customize the appearance of table view cells. - (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]; } // Configure the cell. NSString *categoryName = [categories objectAtIndex:indexPath.row]; cell.textLabel.text = categoryName; return cell; } // Override to support row selection in the table view. - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { printf("User selected row %d\n", [indexPath row] + 1); ButtonsPageViewController *bView = [ButtonsPageViewController alloc]; NSLog(@"created instance of buttonspageviewcontroller"); NSString *categoryName = [categories objectAtIndex:indexPath.row]; NSLog(@"category name set"); bView.selectedCategory = categoryName; NSLog(@"selected category property set"); [self.navigationController pushViewController:bView animated:YES]; NSLog(@"push view controller"); [bView release]; } </code></pre>

    2. COAnd what *is* `[categories objectAtIndex:indexPath.row]`? Have you looked at this in a debugger? Or even just NSLog debugging?

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.

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