title: How do I set the height to a tableFooterView loaded from a xib
body: <p>I have a <code>UITableView</code>, I'm adding <code>tableFooterView</code> loaded from a xib.</p>
  <pre><code>var footer = NSBundle.mainBundle().loadNibNamed(&quot;AFooterView&quot;, owner: self, options: nil).first as! AFooterView
  self.tableView.tableFooterView = footer
  </code></pre>
  <p>This works fine, but I need to be able to set the height for this footer. The xib only has a <code>UIImageView</code> centered vertically and horizontally so it will adapt whatever the height of the view is.</p>
  <p>I have no clue how to do this with <code>AutoLayout</code>? What would be the right path to follow?</p>
