    copied!<p>Hoping someone can advise me on the correct method to populate a <code>UITableViewCell</code> with custom labels. I keep running into the same issues , either the label is blank or when the table fills up with <code>cells</code> reused ones show overlapping <code>label</code> text.</p> <p>I have followed what has been advised for others here but each way I do it something breaks.</p> <p>** Update **</p> <p>I have changed the code to below and have most of it working except when I select a cell the label overlaps as in the screenshot below. The code for the tutorial I am using can be found here: <a href="https://github.com/funkyboy/Core-Data-on-iOS-5-Tutorial--How-To-Work-with-Relations-and-Predicates" rel="nofollow noreferrer">https://github.com/funkyboy/Core-Data-on-iOS-5-Tutorial--How-To-Work-with-Relations-and-Predicates</a></p> <p>Here is my code:</p> <pre><code>- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *CellIdentifier = @"Cell"; UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier]; if (!cell) { cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier]; } FailedBankInfo *info = [_fetchedResultsController objectAtIndexPath:indexPath]; CGRect infoFrame = CGRectMake(10, 10, 200, 16); UILabel *infoLabel = [[UILabel alloc] initWithFrame:infoFrame]; infoLabel.textColor = [UIColor blackColor]; infoLabel.backgroundColor = [UIColor yellowColor]; infoLabel.font = [UIFont systemFontOfSize:12]; infoLabel.textAlignment = NSTextAlignmentCenter; infoLabel.tag = indexPath.row; infoLabel.text = [NSString stringWithFormat:@"%@, %@", info.city, info.state]; [cell addSubview:infoLabel]; return cell; } - (void)configureCell:(UITableViewCell *)cell atIndexPath:(NSIndexPath *)indexPath { FailedBankInfo *info = [_fetchedResultsController objectAtIndexPath:indexPath]; UILabel *theLabel = (UILabel *)[cell.contentView viewWithTag:indexPath.row]; theLabel.text = [NSString stringWithFormat:@"%@, %@", info.city, info.state]; } </code></pre> <p>Because I am using the Prototype <code>Cell</code> with Core Data and <code>fetchedresultcontroller</code> the <code>if(!cell)</code> is never called. I changed the tag to be the indexPath.row number. Every tutorial I have followed works fine if you use the predefined <code>cell</code> types. If I use Custom with my own labels it never works out. Should I not use a fetchedresultscontroller for the tableview data? If I change the city title in the detail view and save it the following code gets called:</p> <pre><code>- (void)controller:(NSFetchedResultsController *)controller didChangeObject:(id)anObject atIndexPath:(NSIndexPath *)indexPath forChangeType:(NSFetchedResultsChangeType)type newIndexPath:(NSIndexPath *)newIndexPath { UITableView *tableView = self.tableView; switch(type) { case NSFetchedResultsChangeInsert: [tableView insertRowsAtIndexPaths:[NSArray arrayWithObject:newIndexPath] withRowAnimation:UITableViewRowAnimationFade]; break; case NSFetchedResultsChangeDelete: [tableView deleteRowsAtIndexPaths:[NSArray arrayWithObject:indexPath] withRowAnimation:UITableViewRowAnimationFade]; break; case NSFetchedResultsChangeUpdate: [self configureCell:[tableView cellForRowAtIndexPath:indexPath] atIndexPath:indexPath]; break; case NSFetchedResultsChangeMove: [tableView deleteRowsAtIndexPaths:[NSArray arrayWithObject:indexPath] withRowAnimation:UITableViewRowAnimationFade]; [tableView insertRowsAtIndexPaths:[NSArray arrayWithObject:newIndexPath] withRowAnimation:UITableViewRowAnimationFade]; break; } } </code></pre> <p>Here are some screenshots:</p> <p><img src="https://i.stack.imgur.com/fnrir.png" alt="storyboard"></p> <p><img src="https://i.stack.imgur.com/55iYy.png" alt="changed cell"></p> <p><img src="https://i.stack.imgur.com/AGWCE.png" alt="selected cell"></p>
