There are a number of libraries that allow you to define different elements of your apps using a CSS style syntax.
A couple of months ago I mentioned the GSFancytext library that allows you to create rich text with formatting options defined within a style sheet.
Today I came across an interesting library that allows you to not only use stylesheets to customize the look of your text, but allows you to use stylesheets witt UIAppearance making it very easy to style your sheets without needing to write lengthy amounts of UIAppearance code.
The library is UISS by Robert Wijas and can be found with documentation on Github here.
A great timesaver when using the UIAppearance protocol.
