FLAnimatedImage is a performant animated GIF engine for iOS:

  • Plays multiple GIFs simultaneously with a playback speed comparable to desktop browsers
  • Honors variable frame delays
  • Behaves gracefully under memory pressure
  • Eliminates delays or blocking during the first playback loop
  • Interprets the frame delays of fast GIFs the same way modern browsers do

It's a well-tested component that powers all GIFs in Flipboard. To understand its behavior it comes with an interactive demo:


Who is this for?

  • Apps that don't support animated GIFs yet
  • Apps that already support animated GIFs but want a higher performance solution
  • People who want to tinker with the code (the corresponding blog post is a great place to start; also see the To Do section below)
