Setting space between some items in stack view
<p>In Interface Builder, I use a horizontal UIStackView and want to place the items as this :</p>

<pre><code>   xx   xx   xx
</code></pre>

<p>every x symbolize an item. Item1 and item2 should be stuck one to the other, but item2 and item3 should be spaced and so on. That means I do not want constant spacing between all the items.</p>

<p>How can I do so ?<br>
(maybe an equivalent of flexible space of toolbars) </p>

<p>Thanks !</p>
