Layering UIItems
<p>How does on layer objects in a view?</p>

<p>I have a number of movable UIImageViews and would like to add a button which should always be a "layer" above the images. </p>

<p>Meaning that the images should not overlap the button when they are moved. They should move behind rather.</p>

<p>How is this done?</p>

<p>Thanks</p>
