title: Unwind segue not working
body: <p>I'm currently doing the tutorial from <a href="https://developer.apple.com/library/IOs/referencelibrary/GettingStarted/RoadMapiOS/SecondTutorial.html#//apple_ref/doc/uid/TP40011343-CH8-SW1" rel="noreferrer"><strong>Apple's Start Developing iOS Apps</strong></a>.</p>
  
  <p>On the Tutorial: Storyboards page (link above), I'm told to make custom classes for two views. For simplicity I'll call them the Table View (has a table) and the Add View (has a text field to add items to the table).</p>
  
  <p>The Table View has a button that links opens up the Add View, and the Add View has two buttons on its navigation bar: Cancel and Done.</p>
  
  <p>I was told to write an empty method <code>unwindToList</code> in the .m file of the Add View:</p>
  
  <pre><code>- (IBAction)unwindToList:(UIStoryboardSegue *)segue
  {
  
  }
  </code></pre>
  
  <p>Then I was told to link both Cancel and Done buttons to the Exit item in the Scene Dock (see image at the bottom), and to pick the method <code>unwindToList</code>. As a result, this is what's supposed to happen, as quoted from the tutorial:</p>
  
  <blockquote>
    <p>Now, run your app. At launch, you see a table view—but there’s no data in it. You can click the Add button and navigate to [the Add View] from [the Table View]. You can click the Cancel and Done buttons to navigate back to [the Table View]."</p>
  </blockquote>
  
  <p>However, when I click Cancel or Done, nothing happens at all. I'm sure both are linked.</p>
  
  <p>Thanks in advance!</p>
