NIStylesheetCache Class Reference

Overview

A simple in-memory cache for stylesheets.

It is recommended that you use this object to store stylesheets in a centralized location. Ideally you would have one stylesheet cache throughout the lifetime of your application.

Using a stylesheet cache with Chameleon

A stylesheet cache must be used with the Chameleon observer so that changes can be sent for a given stylesheet. This is because changes are sent using the stylesheet object as the notification object, so a listener must register notifications with the stylesheet as the object.

NIStylesheet* stylesheet = [stylesheetCache stylesheetWithPath:@"common.css"];
NSNotificationCenter* nc = [NSNotificationCenter defaultCenter];
[nc addObserver:self
       selector:@selector(stylesheetDidChange)
           name:NIStylesheetDidChangeNotification
         object:stylesheet];
