NSAttributedString HTML Additions

This project aims to duplicate the methods present on Mac OSX which allow creation of NSAttributedString from HTML code on iOS.

This is useful for drawing simple rich text like any HTML document without having to use a UIWebView.

Features

At present the following tags are supported:

  • Headers H1 - H6
  • Paragraphs: P
  • Bold: B, STRONG
  • Italic: I, EM
  • Underline: U
  • Superscript: SUP
  • Subscript: SUB, e.g. e = mc2
  • Styling: FONT (face and color, not size). It would be great if we could support many more styles
  • Unordered Lists: UL, LI
  • Ordered Lists: OL, LI

Currently attributes are inherited by enclosed tags via 'brute force'. I don't know if this is accurate.

To Do

NSAttributedString+HTML

  • Decode HTML Entities
  • A HREF tags, to format links
  • More styles, as far as supported by CoreText

DTAttributedTextView

  • Run Delegate: make room for IMG and draw the IMG
  • Run Delegate: Characters with super/subscript need baseline adjusted when drawn
  • Caret Positioning
  • Hit Detection on strings attributed with HREF
  • Text Insertion
  • Editing!

There is still quite a few more things to do on the project. DEL, possibly CSS styles as they related to fonts and text formatting.

Please Help!

If you find brief test cases where the created NSAttributedString differs from the version on OSX please send them to us!
