  <p>Above is my storyboard. As you can see, view a and view b are both on the same navigation controller. They are both show segues. The segue to View B is activated manually by a button on the subview on the view of the previous "Home" controller and that works perfectly and has a back button. Here's the code:</p>
  
  <pre><code>- (void)storyButtonPressed:(UIButton *)button {
      [self performSegueWithIdentifier:@"showStory" sender:self];
  }
  </code></pre>
  
  <p>The segue to view A is activated manually by an if statement to see if the user is registered:</p>
  
  <pre><code>if (currentUser.active != true) {
      [self performSegueWithIdentifier:@"showSignUp" sender:self];
  }
  </code></pre>
  
  <p>However view A will not show up with a back button even though I'm going about it just like view B. I even tried to add a button to the navbar and manually pop off the view but that button won't even show up! Here's my document outline:</p>

  <p>How do I get my view A to have a back button or at least allow me to add one manually?</p>
  
  <p>Thank you.</p>
