title: Calling methods between view controllers using Storyboard
body: <p>I've already read the post Passing data to views using Storyboards, but still have problem with calling methods:</p>
  
  <p>Now I have <code>AViewController</code> and <code>BViewController</code>, both connected with Storyboard (no XIBs).</p>
  
  <p>In BViewController :</p>
  
  <pre><code>-(void)doSth:(int)num;
  </code></pre>
  
  <p>So how can I call the <code>doSth:</code> method in <code>AViewController</code>?</p>
  
  <p>The old way like <code>[bViewController doSth:123];</code> don't work because I can't get the instance of <code>BViewController</code> in the Storyboard.</p>
  
  <p>Thanks.</p>
