title: How to not show intermediate screen and call viewWillAppear when we are dismissing two view controllers back
body: <p>Let's say I have 3 UIViewControllers: <strong>A</strong>, <strong>B</strong>, <strong>C</strong>. <strong>A</strong> is presenting <strong>B</strong> modally and <strong>B</strong> is presenting <strong>C</strong> modally. I have exit segue from <strong>C</strong> to <strong>A</strong> and everything works fine, but while dismissing controller <strong>B</strong> is flashing and it's <code>viewWillAppear</code> is called. 
  Is it possible not to show <strong>B</strong> and don't call it's <code>viewWillAppear</code> in this situation?</p>
