    <p>I have a set up tableView which works fine. As you can see below I want to add an image to my cell when the value for the object @"sent" changes to @"yes". After this is done i call [sendTable reloadData] but nothing happens to the tableView. Only when I restart the app my image is properly shown in the cell. So obviously reloadData isn't doing anything here. </p> <p>Can anybody figure out the problem?</p> <pre><code>- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { UITableViewCell *cell; if (tableView == sendTable) { NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); NSString *documentsDirectory = [paths objectAtIndex:0]; NSString *writableDBPath = [documentsDirectory stringByAppendingPathComponent:@"savedItems.plist"]; savedItemsArray = [NSMutableArray arrayWithContentsOfFile:writableDBPath]; NSDictionary* item = [savedItemsArray objectAtIndex:indexPath.row]; NSString *temp = [NSString stringWithFormat:@"%@,%@", [[savedItemsArray valueForKey:@"name"]objectAtIndex:indexPath.row], [[savedItemsArray valueForKey:@"message"]objectAtIndex:indexPath.row]]; UIView *background; cell = [self.sendTable dequeueReusableCellWithIdentifier:temp]; if (cell == nil) { cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:temp]; cell.accessoryType = UITableViewCellAccessoryDetailDisclosureButton; cell.selectionStyle = UITableViewCellSelectionStyleGray; background = [[UIView alloc] initWithFrame:cell.frame]; [cell addSubview:background]; [cell sendSubviewToBack:background]; } if ([[item objectForKey:@"sent"] isEqualToString: @"no"]) { UILabel *personLabel = [[UILabel alloc]initWithFrame:CGRectMake(10, 10, cell.frame.size.width-150, 20)]; personLabel.backgroundColor = [UIColor clearColor]; personLabel.text = [NSString stringWithFormat: @"%@",[item objectForKey:@"name"]]; personLabel.font = [UIFont boldSystemFontOfSize:17]; UILabel *personLabel2 = [[UILabel alloc]initWithFrame:CGRectMake(10, 30, cell.frame.size.width-150, 20)]; personLabel2.backgroundColor = [UIColor clearColor]; personLabel2.text = [NSString stringWithFormat: @"(%@)", [item objectForKey:@"number"]]; personLabel2.font = [UIFont systemFontOfSize:15]; UILabel *dateLabel = [[UILabel alloc]initWithFrame:CGRectMake(cell.frame.size.width-125, 10, 80, 40)]; dateLabel.backgroundColor = [UIColor clearColor]; dateLabel.text = [NSString stringWithFormat: @"%@\n%@",[item objectForKey:@"date"], [item objectForKey:@"time"]]; dateLabel.textColor = [UIColor darkGrayColor]; dateLabel.textAlignment = NSTextAlignmentRight; dateLabel.font = [UIFont systemFontOfSize:13]; dateLabel.numberOfLines = 2; UILabel *messageLabel = [[UILabel alloc]initWithFrame:CGRectMake(10, 60, cell.frame.size.width-50, 20)]; messageLabel.backgroundColor = [UIColor clearColor]; messageLabel.text = [NSString stringWithFormat: @"%@",[item objectForKey:@"message"]]; messageLabel.textColor = [UIColor lightGrayColor]; messageLabel.font = [UIFont systemFontOfSize:15]; [background addSubview:personLabel]; [background addSubview:personLabel2]; [background addSubview:dateLabel]; [background addSubview:messageLabel]; [cell addSubview:background]; }else{ UILabel *personLabel = [[UILabel alloc]initWithFrame:CGRectMake(40, 10, cell.frame.size.width-170, 20)]; personLabel.backgroundColor = [UIColor clearColor]; personLabel.text = [NSString stringWithFormat: @"%@",[item objectForKey:@"name"]]; personLabel.font = [UIFont boldSystemFontOfSize:17]; UILabel *personLabel2 = [[UILabel alloc]initWithFrame:CGRectMake(40, 30, cell.frame.size.width-170, 20)]; personLabel2.backgroundColor = [UIColor clearColor]; personLabel2.text = [NSString stringWithFormat: @"(%@)", [item objectForKey:@"number"]]; personLabel2.font = [UIFont systemFontOfSize:15]; UILabel *dateLabel = [[UILabel alloc]initWithFrame:CGRectMake(cell.frame.size.width-125, 10, 80, 40)]; dateLabel.backgroundColor = [UIColor clearColor]; dateLabel.text = [NSString stringWithFormat: @"%@\n%@",[item objectForKey:@"date"], [item objectForKey:@"time"]]; dateLabel.textColor = [UIColor darkGrayColor]; dateLabel.textAlignment = NSTextAlignmentRight; dateLabel.font = [UIFont systemFontOfSize:13]; dateLabel.numberOfLines = 2; UILabel *messageLabel = [[UILabel alloc]initWithFrame:CGRectMake(40, 60, cell.frame.size.width-80, 20)]; messageLabel.backgroundColor = [UIColor clearColor]; messageLabel.text = [NSString stringWithFormat: @"%@",[item objectForKey:@"message"]]; messageLabel.textColor = [UIColor lightGrayColor]; messageLabel.font = [UIFont systemFontOfSize:15]; UIImage *checkmarkImage = [UIImage imageNamed:@"done.png"]; UIImageView *checkmark = [[UIImageView alloc] initWithImage:checkmarkImage]; [checkmark setFrame:CGRectMake(10, 35, 20, 20)]; [background addSubview:personLabel]; [background addSubview:personLabel2]; [background addSubview:dateLabel]; [background addSubview:messageLabel]; [background addSubview:checkmark]; [cell addSubview:background]; } } return cell; } </code></pre> <p>Thanks a lot!</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.

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).
