title: presentModalViewController from UIModalTransitionStylePartialCurl viewController
body: <p>I have a modal view that is presented via <code>UIModalTransitionStylePartialCurl</code> transition. In that modal view there is a button, which I would like to:</p>
  
  <ol>
  <li>dismiss the current modal view (curl down), then</li>
  <li>present a new modal view (cover vertical).</li>
  </ol>
  
  <p>However, when I try the following, it simply dismisses the curl modal view but doesn't present the new one:</p>
  
  <pre><code>[self dismissModalViewControllerAnimated:YES];
  NewView *vc = [[NewView alloc] init];
  [self.parentViewController presentModalViewController:vc animated:YES];
  </code></pre>
  
  <p>I have a feeling it has to do with that last line. Presenting NewView on <code>self</code> doesn't work either. How can I accomplish this?</p>
