This Gist work with [UIButton+AFNetworking.h]

Readme.md

This Gist work with [UIButton+AFNetworking.h] (https://gist.github.com/dpettigrew/2925847) a very useful category for UIButton.

And is inspired by this stackOverflow [answer] (http://stackoverflow.com/a/10255257), just need a few touches.

With this UIButton subclass you can setup buttons with cornerRadius and shadows even with downloaded images from internet.

To use this class you can set a cornerRadius inside, previous setup is called or after setup the images, set the cornerRadius and call setupView. Anyone can use this gist as he wish, see license inside.
