title: Subclassing UITableViewCell with its own Nib
body: <p>I'd like to create a custom UITableViewCell subclass that loads content asynchronously using a URL connection. I've got a UITableViewCell subclass that handles all of this and a Nib file that defines the layout of the cell, but I'm having trouble linking the two. Here's the code I'm using in <code>tableView:cellForRowAtIndexPath</code>:</p>
  
  <pre><code>static NSString *FavCellIdentifier = @"FavCellIdentifier";
  
  FavouriteCell *cell = [tableView dequeueReusableCellWithIdentifier:FavCellIdentifier];
  
  if (cell == nil)
  {
      cell = [[[FavouriteCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:FavCellIdentifier] autorelease];
  }
  
  cell.requestURL = [NSURL URLWithString:[NSString stringWithFormat:@"%@?%@=%i", URL_GET_POST_STATUS,
                                             URL_PARAM_SERIAL,
                                             [[self.favourites objectAtIndex:indexPath.row] intValue]]];
  
  return cell;
  </code></pre>
  
  <p>This gives a request URL to the UITableViewCell subclass, which handles loading in the <code>setRequestURL</code> method.</p>
  
  <p>In the FavouriteCell class I've kept the <code>initWithStyle:reuseIdentifier:</code> method as is, and in the Nib I've set FavCellIdentifier as the identifier, and FavouriteCell as the class. Now how do I make the FavouriteCell class load the Nib?</p>
