NIStylesheet Class Reference

Overview

Loads and caches information regarding a specific stylesheet.

Use this object to load and parse a CSS stylesheet from disk and then apply the stylesheet to views. Rulesets are cached on demand and cleared when a memory warning is received.

Stylesheets can be merged using the addStylesheet: method.

Cached rulesets are released when a memory warning is received.
