title: IOS: open and close some view controllers
body: <p>In my app I have the following configuration to open my view controllers:</p>
  
  <p>When I write <strong>"pushViewController"</strong> I use a navigation controller, and when I write <strong>"present"</strong> I use a <code>presentModalViewController</code>.</p>
  
  <pre><code>firtsView -&gt; (pushviewcontroller) -&gt; secondOneView -&gt; (present) -&gt; thirdOneView -&gt; (present) -&gt; fourthView
  
  firstView -&gt; (pushviewcontroller) -&gt; secondTwoView -&gt; (present) -&gt; thirdTwoView 
  </code></pre>
  
  <p>This is the scheme of my app to organize my view controllers. Then my question is:</p>
  
  <p>What's the way to return from <strong>"fourthView"</strong> (that is when I go back from <strong>"fourthView"</strong>) to <strong>"secondTwoView"</strong>? </p>
  
  <p>Is there a way to do it?</p>
