NSAttributedString+DDHTML

Simplifies working with attributed strings by allowing you to use HTML to describe formatting behaviors.

NSAttributedString+DDHTML isn't intended to support full HTML rendering. Instead it provides a quick, effient and light-weight implementation for leveraging attributed strings when utilizing native UIKit interface elements.

License


It is open source and covered by a standard BSD license. That means you have to mention Derek Bowen @ Deloite Digital as the original author of this code.

NSAttributedString+DDHTML requires a minimum iOS deployment target of iOS 4.3 becuse of:

  • ARC

Setup


  1. Add NSAttributedString+DDHTML.m/h to your project.
