title: How do I make a sticky footer banner in ScrollView? (Xcode)
body: <p>I have a <code>ScrollView</code> hierarchy that looks like <a href="https://i.stack.imgur.com/auP71.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/auP71.png" alt="this"></a>, the adView that I want to turn into a sticky footer banner being marked. How do I make the footer stick to the bottom of the screen at all times, even though I scroll down the page? My first thought was to pin it straight to the <code>mainView</code> or the <code>scrollView</code>, but if I place the <code>adView</code> anywhere else, it gets covered by the other views. I have looked for a proper tutorial but ended up empty handed. The information is either too old or irrelevant to what I'm trying to do. Can anyone point me to a good guide, or explain how to accomplish this? :) </p>
