title: Application tried to push a nil view controller on target
body: <p>I got the below error:</p>
  
  <p><code>Application tried to push a nil view controller on target UINavigationController: 0x7b98940.</code></p>
  
  <p>It is caused when I 'click' a cell of an <code>UITableViewController</code>.
  Code:</p>
  
  <pre><code>#pragma mark - Table view delegate
  
  - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
  {
      VerifyInfoViewController *verifyInfoVC = [self.storyboard instantiateViewControllerWithIdentifier:@"verifyInfoVC"];
      [self.navigationController pushViewController:verifyInfoVC animated:YES];
  }
  </code></pre>
