  <p>I'm making an email app in which I first started off with embedding the ViewController in Navigation bar, after which I made a "FirstView" in which I added three buttons connecting them  to another ViewController for a detailed page. They worked fine, But when I tried to connect another button from the new viewcontroller to viewcontroller.h, It doesn't show any option to. </p>

  <p>Any idea how can I do this?</p>
