  <p>Hello,
  so i have this <code>storyboard</code> structure i have a <code>button</code> in <code>ViewController B</code> i need that <code>button</code> to point to the bottom <code>NavigationController</code> in which it has the <code>ViewController C</code> as <code>rootViewController</code> so when i press a <code>button</code> in <code>ViewContoller B</code> it takes me to <code>C</code> now i need a back button on <code>C</code> to take me back to <code>B</code></p>
  
  <p>i have tried looking but all of the reference materials show how to navigate between <code>ViewController</code> not <code>NavigationControllers</code></p>
