title: UIStackView - Distribute views evenly from the centre
body: <p>I have a <code>UIStackView</code>,inside a <code>UIScrollView</code> to show dynamically added subviews horizontally arranged. Current solution will start displaying items from the left, I would like to start distributing items from the centre without changing the width and height of the subviews. How do I do that?  Im also open to solutions which doesn't use <code>UIStackView</code> as well. That way I could support devices &lt; iOS9.</p>
