title: Resizing custom UITableViewCell's subviews on creation
body: <p>I'm attempting to create a custom UITableViewCell with its own XIB, of which contains two important, editable components:</p>
  
  <ul>
  <li>UILabel</li>
  <li>UIImage with 'end-cap insets' - this image sits behind the label, and resizes with it</li>
  </ul>
  
  <p>When I create my UITableViewCell I can set its label's text easily, but in the same method I also try to change the UIImage's frame to match that of the UILabel's. However, this is not happening until I 'reload' the cell by scrolling the table view to dequeue it and bring it back into view.</p>
  
  <p>I create the custom table view cell in my view controller's .m:</p>
  
  <pre><code>- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
  
      static NSString *UITableViewCellIdentifier = @"msgCell";
  
      RMMessageCell *cell = [tableView dequeueReusableCellWithIdentifier:UITableViewCellIdentifier];
  
      if (cell == nil) {
          NSArray *topLevelObjects = [[NSBundle mainBundle] loadNibNamed:@"MessageCell" owner:self options:nil];
          cell = [topLevelObjects objectAtIndex:0];
          [cell customInit]; //This sets up the ImageView's image etc
      }
  
      [cell setMessageValue:[_messages objectAtIndex:indexPath.row]]; //SEE BELOW
  
      return cell;
  }
  </code></pre>
  
  <p>...And in my custom cell's .m, I deal with setting the text label and resizing the image with this method:</p>
  
  <pre><code>- (void)setMessageValue:(NSString *)message {
  
      _testLabel.text = message;
      // Assume the text label's frame has already been set to the message's length 
      // (will add this in once I figure out how to change the imageView's 
      // frame correctly)
  
      // Set the image view's frame to the label's
      // THIS DOES NOT TAKE EFFECT UNTIL THE TABLE VIEW IS RE-SCROLLED
      CGRect frame = _imageView.frame;
      frame.size.width = _testLabel.frame.size.width + 8;
      _imageView.frame = frame;
  }
  </code></pre>
