title: Losing navigation controller how to open another view
body: <p>I'm currently displaying a UIViewController like this:</p>
  
  <pre><code>AlaramDetail *alaramDetail = [[AlaramDetail alloc] init];
  alaramDetail.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal;
  [self presentModalViewController:alaramDetail animated:YES];
  [alaramDetail release];
  </code></pre>
  
  <p>all works good but i lose the navigation controller when AlarmDetail opens. i want to open another view from alarmDetail how can i do so.
  and how can i return back to my previous navigation controller if i want ?
  Thx</p>
