- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath  {
static NSString *CellIdentifier = @"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
    cell = [[[NSBundle mainBundle] loadNibNamed:@"CCell" owner:self options:nil] objectAtIndex:0];

}
UILabel *lbl=(UILabel*)[cell viewWithTag:1];
UIImageView *imgV = (UIImageView*)[cell viewWithTag:2];
UILabel *label=(UILabel*)[cell viewWithTag:3];

 NSDictionary *dToAccess = [self.listOfItems objectAtIndex:indexPath.row];
[lbl setText:[dToAccess valueForKey:@"title"]];
NSUInteger intVal = [[dToAccess valueForKey:@"rating"] integerValue];
switch (intVal) {
    case 0:
        [imgV setImage:[UIImage imageNamed:@"0star.png"]];
        [label setText:@"Snitt 0"];
        label.textColor=[UIColor blueColor];
        break;
    case 1:
        [imgV setImage:[UIImage imageNamed:@"1star.png"]];
        [label setText:@"Snitt 1"];
        break;
    case 2:
        [imgV setImage:[UIImage imageNamed:@"2star.png"]];
        [label setText:@"Snitt 2"];
        break;
    case 3:
        [imgV setImage:[UIImage imageNamed:@"3star.png"]];
         [label setText:@"Snitt 3"];
        break;
    case 4:
        [imgV setImage:[UIImage imageNamed:@"4star.png"]];
        [label setText:@"Snitt 4"];
        break;
    case 5:
        [imgV setImage:[UIImage imageNamed:@"5star.png"]];
        [label setText:@"Snitt 5"];
        break;
    default:
        break;
}
CGSize size = [lbl.text sizeWithFont:[UIFont boldSystemFontOfSize:16] forWidth:205 lineBreakMode:UILineBreakModeCharacterWrap];
[lbl setFrame:CGRectMake(5, 0, size.width, 43)];

[imgV setFrame:CGRectMake(5+size.width+5, 4, 118, 36)];

return cell;
}

You can get the detail label cell color for UITableViewCellStyleValue1 by doing:

UITableViewCell *cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleValue1 reuseIdentifier:@"resuse"];
UIColor *lightBlueColor = cell.detailTextLabel.textColor;

which can be broken down into it’s RGB values and alpha by doing:

const float* colors = CGColorGetComponents( lightBlueColor.CGColor );

It’s up to you if you want to hardcode the values in code or just compute it every time. I’d say hardcode would be better.
