MGEStyles/Goya

https://github.com/ManueGE/MGEStyles
An easy way to set custom styles to any UIResponder from the Interface Builder.

As an iOS developer, I felt very often frustrated with how difficult is to set consistent styles to my views in the Xcode Interface Builder. If you think in a UILabel, you can use the same style (font, color and size) for a set of labels in different UIViewController. If, some time later, the design changes you'll have to change the properties of all these labels one by one, which is a tedious work. I try to solve this issue by developing MGEStyles. This library, inspired by the Android styles system, simplifies this task, giving you the chance of define a totally custom styles in one single place and using it all over your project, using the Interface Builder or by code.
