title: Navigation button changes color to grey after transition
body: <p>I can make push transition with 'Add button' but I need also do it programmatically. When I do it programmatically and then I go back 'Add button' becomes grey. I debugged it and I can see that the _defualtAttributes have changed in _titleView. The color value has changed. Why is it changing? How to prevent from it? It looks confusing.</p>
  
  <pre><code>-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
  {
      AddPalletViewController * addPalletViewController = [self addPalletViewControllerInstance];
      [addPalletViewController setEditMode:true];
      [addPalletViewController setEditModeRowValue: [[self.datasource objectAtIndex: indexPath.section] objectAtIndex: [[[self.sectionArray objectAtIndex:indexPath.section] objectAtIndex:indexPath.row+1]intValue]]];
      [[self navigationController] pushViewController: addPalletViewController animated:YES];
  }
  </code></pre>
