cell.textLabel not getting resized - iphone

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.
