Adding UILabel to UIImageView in CellForRow - ios5

Question

I have a customCell in StoryBoard "CategoryCell", I have UIImageView with the cell which is also part of the cell also tied up in StoryBoard. The UIImageView is filled with a plain yellow color. I intend to add a label to this plain yellow image, the label varies depending on the cell.
The code below works fine initially, but when I scroll the the tableView, I see label in the image getting messed up, it's like its trying to write new text in top of the text. I figured it's hitting cellForRow again and it's adding new label, How can I make it not create new label on top of old one?
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
if([tableView isEqual:wordsTableView])
{
CategoryCell *cell = [CategoryTableView dequeueReusableCellWithIdentifier:#"CategoryCellIdentifier" forIndexPath:indexPath];
if(!cell)
cell = [[CategoryCell alloc] initWithStyle:UITableViewStylePlain reuseIdentifier:#"CategoryCellIdentifier"];
NSString *text = [[theCategories objectAtIndex:indexPath.row] uppercaseString];
//Add label now
catLabel = [[UILabel alloc] initWithFrame:CGRectMake(10, 10, 40, 20)];
catLabel.text = text;
[cell.codeImageView addSubview:catLabel];
return cell;
}

Answer 1

You could give the label a tag and use that to check to see if it exists before creating it again :
UILabel *catLabel = [cell.codeImageView viewWithTag:100];
if (nil == catLabel) {
catLabel = [[UILabel alloc] initWithFrame:CGRectMake(10, 10, 40, 20)];
catLabel.tag = 100;
[cell.codeImageView addSubview:catLabel];
}
catLabel.text = text;
Though if it gets any more complicated I might look at subclassing UITableViewCell and using a xib to instantiate the label.
