Question

I’m trying to create a Settings for our app. I’m not sure what is happening here. I have a UITableViewSyleGrouped and in each section of the table, there is 1 row. For my particular row, it shows the person’s name. If you click on it, then it pushes to a new tableView that has the list of people to choose from, then when you pop back, the label gets updated, but the label is truncated when I go from a smaller name to a bigger name. I’m trying to create a Settings for our app. Some of the fields look like:

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    NSUInteger row = [indexPath row];
    if (tableView == _settingsTableView) {
        UITableViewCell *cell = nil;

        NSNumber *aSection = [_tableArray objectAtIndex:indexPath.section];

        if ([aSection integerValue] == SOUNDS)
        {
            cell = [tableView dequeueReusableCellWithIdentifier:@"SwitchCell"];
            if (cell == nil)
            {
                cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:@"SwitchCell"] autorelease];
            }
            cell.textLabel.text = @"Sounds";
            cell.selectionStyle = UITableViewCellSelectionStyleNone;
            UISwitch *switchView = [[UISwitch alloc] initWithFrame:CGRectZero];
            cell.accessoryView = switchView;
            [switchView setOn:[[Settings sharedInstance] playSounds] animated:NO]; // initialize value from Settings
            [switchView addTarget:self action:@selector(switchChanged:) forControlEvents:UIControlEventValueChanged];
            [switchView release];
        }
        else if ([aSection integerValue] == PERSON) {
            cell = [tableView dequeueReusableCellWithIdentifier:@"PersonCell"];
            if (cell == nil) {
                cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleValue1 reuseIdentifier:@"PersonCell"] autorelease];
            }
            Person *p = [_personArray objectAtIndex:row];
            cell.textLabel.text = [NSString stringWithFormat:@"%@ %@", p.firstName, p.lastName];
                        NSLog(@"cL: %@", NSStringFromCGRect(cell.textLabel.frame));
            cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator; 
            cell.selectionStyle = UITableViewCellSelectionStyleNone;
        }
  return cell;
}

My PERSON section gives the user the ability to change People. That code in didSelectRowAtIndexPath is

else {
    Person *p = [_personArray objectAtIndex:row];
    NSUInteger oldRow = [_lastIndexPath row];
    if (oldRow != row) {
        dmgr.currentPerson = p;

        // Put checkmark on newly selected cell
        UITableViewCell *cell = [tableView cellForRowAtIndexPath:indexPath];
        cell.selectionStyle = UITableViewCellSelectionStyleNone;
        cell.accessoryType = UITableViewCellAccessoryCheckmark;

        // Remove checkmark on old cell
        UITableViewCell *oldCell = [tableView cellForRowAtIndexPath:_lastIndexPath];
        oldCell.accessoryType = UITableViewCellAccessoryNone;
        [_settingsTableView deselectRowAtIndexPath:_lastIndexPath animated:YES];
        self.LastIndexPath = indexPath;

        // Update the cell 
        NSIndexPath *path = [NSIndexPath indexPathForRow:0 PERSON];
        UITableViewCell *theCell = [_settingsTableView path];

        theCell.textLabel.text = [NSString stringWithFormat:@"%@ %@", p.firstName, p.lastName];
        [theCell setNeedsDisplay];                
        NSLog(@"ceLL: %@", NSStringFromCGRect(theCell.textLabel.frame));

    }
}

What happens is the label is truncated until I click on the label. (e.g. John D… instead of John Doe). Why does the label not get updated?

I tried looking at the frames, and I’m not sure if that has something to do with it or not. My output is:

cL: {{0, 0}, {0, 0}}
ceLL: {{10, 11}, {76, 21}}

The textLabel field of a UITableViewCell is a regular UILabel. You can set this property to cause it to scale down the text to fit:

 theCell.textLabel.adjustsFontSizeToFitWidth = YES;

You can also set a minimum font size

 theCell.textLabel.minimumFontSize  = whatever

Take a look at the Documentation on UILabel it will help you a lot.
