Looking for an "Zoom"-effect event handler for UICollectionViewCell in tvOS
<p>I have to do something in case of a <code>UICollectionViewCell</code> will be zoom out (hover state).</p>

<p>I thought that this effect updates the bounds of the cell and I've overridden the bound variable.</p>

<p>But the <code>didSet</code>method will be only triggered for the first time (original size) and not for the new size during the zooming.</p>

<pre><code>override var bounds: CGRect
{
    didSet
    {
        // do some magic
    }
}
</code></pre>

<p>What would be the correct way catch this kind of event?</p>
