A category on NSString for quickly generated attributed strings from HTML-style tags.

Basics:

Opening Tags: <>

Closing Tags: </>

Multiple commands can be used in a single tag. For example: <b, i, u>. These should be comma seperated. Commands are closed by listing them in a closing tag: </b, i, u>

For commands that take an arguement, an equals sign with no quotes are required. For example: <c=red, font=Georgia>

Commands are parsed linearly, and not nested. Each new command will override previous commands. For exmaple, "<c=red>Hello <c=blue>World</c>!" will result in a red "Hello", blue "World", and a black (uncolored) "!".

Fonts and colors can be described in a nil terminated list using attributedStringFromTaggedStringWithFontsAndColors. They should be of type UIFont and UIcolor. The fonts and colors can be referenced by their position by type in the list using @1, @2, etc. For example, if you pass (in order) myFont1, myColor1, myFont2, myFont3, myColor2, then those can be accessed by font=@1, c=@1, font=@2, font=@3, color=@2 respectively. For example: [@"<font=@1>Hello World</font>" attributedStringFromTaggedStringWithFontsAndColors:myFont];

Color Commands:

• c=, cf= - Foreground Text Color
• cb= - Background Text Color
• tc= - Strikethrough Color

Font Color:

• family= - Set the family name for a font. Use family= to set a font that can be bolded, italicized, or bold ital. Bold, italic, and bold italic are only availiable if a family has been set. The default family is HelveticaNeue. This must match a family name in the project.
• face= - Set Font Face. This must match a font name in the project.
• b - Bold (must have set a family).
• i - Italic (must have set a family).
• s= - Size (float value).

Alignment:

• a= - Options: left, right, center, justified, natural.

Underline:

• u - Underlines text

Strikethrough:

• t - Strikethrough text. The line will be the same color as the current text color, unless the strikethrough color has been specified (see above).
