title: Is there a way to integrate the cloud icon to download content
body: <p>I made a Calculus video app and I would like to add the capability to download the videos for offline use. I could create a button and have my own icon of course but I am trying to see if there is a way to integrate the little cloud icon that apple uses in its WWDC app (and App store app) for downloads(see screenshot below) <a href="https://i.stack.imgur.com/4D96P.jpg" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/4D96P.jpg" alt="cloud icon"></a></p>
