Loading a Reusable UITableViewCell from a Nib

Question

I am able to design custom UITableViewCells and load them just fine using the technique described in the thread found at http://forums.macrumors.com/showthread.php?t=545061.

This technique also works and doesn't require a funky ivar in your view controller for memory management. Here, the custom table view cell lives in a xib named "CustomCell.xib".

 static NSData *sLoadedCustomCell = nil;

 cell = [tableView dequeueReusableCellWithIdentifier:@"CustomCell"];
 if (cell == nil) 
 {
   if (sLoadedCustomCell == nil) 
   {        
      // Load the custom table cell xib
      // and extract a reference to the cell object returned
      // and cache it in a static to avoid reloading the nib again.

      for (id loadedObject in [[NSBundle mainBundle] loadNibNamed:@"CustomCell" owner:nil options:nil]) 
      {
        if ([loadedObject isKindOfClass:[UITableViewCell class]]) 
        {
          sLoadedCustomCell = [[NSKeyedArchiver archivedDataWithRootObject: loadedObject] retain];
          break;
        }
    }
    cell = (UITableViewCell *)[NSKeyedUnarchiver unarchiveObjectWithData: sLoadedCustomCell];
  }
