Examining Fonts

In addition to converting fonts, NSFontManager provides information on which fonts are available to the application and on the characteristics of any given font. The availableFonts method returns an array of the names of all fonts available. The availableFontNamesWithTraits: method filters the available fonts based on a font trait mask.

There are three methods for examining individual fonts. The fontNamed:HasTraits: method returns true if the font matches the trait mask provided. The traitsOfFont: method returns a trait mask for a given font. The weightOfFont: method returns an approximate ranking of a font’s weight on a scale of 0–15, where 0 is the lightest possible weight, 5 is Normal or Book weight, 9 is the equivalent of Bold, and 15 is the heaviest possible (often called Black or Ultra Black).
