title: UITableViewCell background view/image
body: <p>Where do I set backgroundImage of tableview cell in cellForRowAt.. And how do I do that ? This is how I did it and it kinda works, but I want to know is that right method for setting backgroundimage (<code>cell.backgroundView</code>) and is it right place inside <code>if(cell==nil)</code> or outside that "if".?</p>
  
  <pre><code>- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {    
      static NSString *cellIdentifier = @"RootViewCellIdentifier";
  
      UITableViewCell *cell = [_tableView dequeueReusableCellWithIdentifier:cellIdentifier];
      if (cell == nil) {
          cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:cellIdentifier];
  
          cell.backgroundView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"image1.png"]];
      }
  
      return cell;
  }
  </code></pre>
