Control of the Week

Aaron Brethorst, February 06, 2012

Welcome to another edition of Control of the Week! This week, I’d like to introduce you to PullToRefreshTransform, from Tom Irving, a Cocoa developer whose work we’ve had the pleasure of featuring before.

PullToRefreshTransform shows you how perform a snazzy version of the (now fairly standard) pull to refresh action using CATransform3D to create an ‘unfolding’ effect. I should point out that, in order to integrate this into your app, you will need to do some work, as this is more of a code sample than a reusable control. Nevertheless, I think it’s cool and novel enough that it deserves a showing here. Also, the source code does not specify a license at present, but I’ve opened up an issue on GitHub asking Tom to clarify the licensing situation. Hope you like!

Go check out the source code, or see it on YouTube, first:
