title: UIImageView slideshow from images downloaded with SDWebImage
body: <p>I'm making app for time lapse photos, I'm using <a href="https://github.com/rs/SDWebImage" rel="nofollow noreferrer">SDWebImage</a> to download+cache photos from server, and I'd like to do slideshow from series of photos. I've tried SDWebImage's method <code>setAnimationImagesWithURLs</code> for UIImageView, which works, but I need to have more control(I don't want to animation start right after viewDidLoad,...). </p>
  
  <p>I imagine that after view controller is shown, it starts to download photos from array of NSURLs, Only first picture is shown, there are play/stop/next controls, and user can tap on them to start animation...</p>
  
  <p>In every tutorial on UIImageView animation, they load images into array, which is used as <code>setAnimationImages:array</code>, but after reading <a href="https://stackoverflow.com/a/19079164/2374802">this answer</a>, it looks like it's not a good idea.</p>
  
  <p>So what's to proper way to do that?</p>
