I've used a similar one myself. Same name but different project: https://github.com/jrturton/UIView-Autolayout/blob/master/So...
Thank you for making this area of ios dev less painful. :)
Damn, I was just getting ready to write a comment recommending UIView+AutoLayout to steal some karma from iOS developers who are not using it yet.
Seriously though, thanks for this! It really makes working with AutoLayout so much easier.
I'm the developer of UIView+AutoLayout, which is designed to provide the API that Apple should have in the first place (it's inspired heavily by the IB options): https://github.com/smileyborg/UIView-AutoLayout
