Yesterday I mentioned a component allowing you to easily replicate the animated view bending effect as seen in the Skype app.

Here’s another project created to show how to replicate the effect of a popular app providing source code example and brief tutorial showing how to recreate the Twitter bird zoom in transition seen when opening the Twitter app from Rounak Jain.

The example uses Swift, and shows how to take a screenshot, set up an image mask, and how to create the zooming effect using Core Animation.

Here’s an animation from the tutorial show’s the created effect:

You can find the tutorial on Rounak’s site here.

You can find the source code on Github here.

A nice straightforward guide to replicating an interesting effect.
