Undocumented methods

+fontWithFamilyName:traits:size:

Signature +(UIFont*)fontWithFamilyName:(NSString*)familyName traits:(GSFontTraitMask)traits size:(CGFloat)fontSize;
Available in 2.0 –

Returns a font with specific family name, traits (bold/italic) and font size. For example: 

// Equivalent to [UIFont fontWithName:@"Arial-BoldMT" size:24]
UIFont* font = [UIFont fontWithFamilyName:@"Arial" traits:GSBoldFontMask size:24];

+fontWithMarkupDescription:

Signature +(UIFont*)fontWithMarkupDescription:(NSString*)markupDescription;
Available in 2.0 —

Create a font using a CSS font description, e.g. 

// Equivalent to [UIFont fontWithName:@"Arial-BoldMT" size:24]
UIFont* font = [UIFont fontWithMarkupDescription:@"font-family: Arial; font-size: 24px; font-weight: bold;"];

Unlike real CSS rules there are heavy restrictions on the "markup description":

  • The font-family rule must be exact. A list of fonts like Arial, Helvetica, sans-serif will not be supported by UIKit, and will always return nil regardless whether any font in the list is available.
  • The unit of font-size will always be interpreted as px. Names such as font-size: large will be considered as 0px.
  • font-weight can only be bold or not.
  • font-style can only be italic or not. In particular, oblique is not recognized and treated as normal.

-traits

Signature -(GSFontTraitMask)traits;
Available in 2.0 –

Returns the traits (bold/italic) of the font.

-isFixedPitch

Signature -(BOOL)isFixedPitch;
Available in 2.0 –

Returns whether the font is monospaced or not.

-markupDescription

Signature -(NSString*)markupDescription;
Available in 2.0 –

Returns the CSS rules that can reproduce this font.
