title: Can you add buttons to navigation bars through storyboard?
body: <p>At the moment, I've been adding navigation buttons like follows:</p>
  
  <pre><code>self.navigationItem.rightBarButtonItem = [[UIBarButtonItem alloc] initWithTitle:@"Add"
                                                                            style:self.editButtonItem.style 
                                                                           target:self
                                                                           action:@selector(doneButtonPressed)];
  </code></pre>
  
  <p>It seems a bit silly to not add them through storyboard, but I can't find a way to do so.  Is there one that I'm missing?</p>
