Pop: An extensible animation engine for iOS and OS X

Pop doesn&#x27;t have any example code yet so I created a video tutorial to help folks get started (with source code): <a href="http://tapity.com/tutorial-getting-started-with-pop/" rel="nofollow">http:&#x2F;&#x2F;tapity.com&#x2F;tutorial-getting-started-with-pop&#x2F;</a>

Also there&#x27;s a blog post with more details of the library at <a href="https://code.facebook.com/posts/234067533455773/introducing-pop-the-animation-engine-behind-paper/" rel="nofollow">https:&#x2F;&#x2F;code.facebook.com&#x2F;posts&#x2F;234067533455773&#x2F;introducing-...</a>

I&#x27;m missing the benefit of this over iOS 7&#x27;s Core animation. I guess support for earlier os versions is the big advantage but for me all my new work is on iOS 7+ only apps and I&#x27;m not sure this helps a ton for that.

<a href="https://github.com/seivan/TransitionControllerWithPop" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;seivan&#x2F;TransitionControllerWithPop</a><p>So I tried with a custom transitionController and it doesn&#x27;t play along nicely without using CADisplayLink.<p>It&#x27;s the same concept as CAAnimation, you need to manually step through the animation.<p>It&#x27;s not bad per say, if you need to morph some layers or animate stuff like shadows or anything that doesn&#x27;t work out of the box with [UIView animate:....]

This is the core animations and interactions library used in Paper app for iOS. I am looking forward to see some examples and tutorials on this, because for someone like me with no experience on UIAnimation, I guess it is something fairly easy to use when there are samples out there.

What are the chances that there will be something similar for Android?

I&#x27;ve been waiting for this ever since reading <a href="http://tapity.com/thank-you-facebook/" rel="nofollow">http:&#x2F;&#x2F;tapity.com&#x2F;thank-you-facebook&#x2F;</a> Hooray!

Awesome! I&#x27;ve been waiting for them to put this up.
