Weekly Roundup

Aaron Brethorst, June 04, 2012

Hi all – We have a really terrific batch of controls for you this week. I know I must sound like a broken record at times, but I am thoroughly impressed with both the technical acumen and the unbounded generosity of the Cocoa developer community. You people really are fantastic :)

On another note, I want to invite you to submit tutorials or other content for inclusion in our blog. We feature tons of great controls from you every week, and would love to have the opportunity to present more in-depth information on how to get the most out of Cocoa, iOS and OS X from you as well. If you’re interested, please drop us a note at [email protected].

Our control of the week is from the ridiculously talented Xiaoyang Feng (no really, go look at his portfolio, he’s unbelievable). XYOrigami is an simple and easy-to-use view transition for iOS app. Inspired by Hon Cheng’s next train video, XYOrigami is a simpler version of folding transition. It is an add-on category of UIView, with two functions you can animate showing/hiding another view. MIT licensed.
