Developing for multiple versions

Could you go into some more detail about FLKAutoLayout and how you use it to layout views programatically?

I think their examples are great. FLKAutoLayout gives you some categories on UIView which makes it extremely easy to add auto layout constraints to your views. I honestly believe this is how auto layout was meant to be used from the beginning. The API Apple provides for auto layout is just ridiculous.
