title: Image of UITableViewCell is not indenting
body: <p>I Have created a default UITableViewCell:</p>
  
  <pre><code>- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
  {
      // Init empty cell
      UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:GroupCellIdentifier];
  
      // Get the group info
      GroupInfo *groupInfo = (GroupInfo *)[_sortedGroupInfos objectAtIndex:[indexPath row]];
  
      // Check if we have initialized this cell before
      if(cell == nil)
      {
          // Initialize cell
          cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:GroupCellIdentifier];
  
          // Set the accessory type
          cell.accessoryType = UITableViewCellAccessoryNone;
  
          // Set the selection type
          cell.selectionStyle = [groupInfo.groupType isEqualToString:GroupTypePersonal] ? UITableViewCellSelectionStyleDefault : UITableViewCellSelectionStyleNone;
  
          // Set the indentation width
          cell.indentationWidth = 40;
      }
  
      // Set the label enabled status depending on the group type
      cell.textLabel.enabled = [groupInfo.groupType isEqualToString:GroupTypePersonal];
      cell.detailTextLabel.enabled = [groupInfo.groupType isEqualToString:GroupTypePersonal];
  
      // Set text
      cell.textLabel.text = groupInfo.description;
      cell.detailTextLabel.text = [NSString stringWithFormat:@"%d %@", groupInfo.storeCount, [[Model instance] getTranslationFromSection:kSectionStoreSettings translationKey:@"Stores"]];
  
      // Set the image depending on the group type
      cell.imageView.image = [GroupInfo getImageForGroupType:groupInfo.groupType];
  
      // Return the cell
      return cell;
  }
  </code></pre>
  
  <p>I also implemented the indentationLevelForRowAtIndexPath function:</p>
  
  <pre><code>- (NSInteger)tableView:(UITableView *)tableView indentationLevelForRowAtIndexPath:(NSIndexPath *)indexPath
  {
      // Get the group info
      GroupInfo *groupInfo = _sortedGroupInfos[[indexPath row]];
  
      // Return the indentation
      return groupInfo.indentation;
  }
  </code></pre>
  
  <p>Now I get the following table view:</p>
  
  <p><a href="http://i40.tinypic.com/f3e63t.png" rel="noreferrer">http://i40.tinypic.com/f3e63t.png</a></p>
  
  <p>My question is: Why is the image not indenting in the table view cell?</p>
