title: Add multiple buttons to navigation bar in storyboard
body: <p>I wonder if this can be achieved using <strong>Storyboard IB</strong>:</p>
  
  <p><code>self.navigationItem.leftBarButtonItems = @[barButton1, barButton2]</code></p>
  
  <p><strong>EDITED:</strong></p>
  
  <p>The purpose is to preserve the benefits of using storyboard and if it's possible <em>without using any lines of code</em>.</p>
  
  <p><strong>EDIT #2:</strong></p>
  
  <p>Based on <a href="https://stackoverflow.com/a/13929183/623396">this answer</a> I experimented and saw that it is possible to link the Title View property of the Navigation Item to a Toolbar

  <p>but it looks to me like a <em>hack</em> (and I might want to preserve the Title as well):</p>

  <p>Any better idea?</p>
