A quick test (in Swift no less) suggests to me that this function just doesn’t work (TM).
I get non-zero results for these 13 flag combinations (count of fonts + mask) and zero results for every other one of the 4096 combinations. 141 NSItalicFontMask 259 NSBoldFontMask 61 NSItalicFontMask + NSBoldFontMask 6 NSExpandedFontMask 3 NSExpandedFontMask + NSBoldFontMask 43 NSCondensedFontMask 12 NSCondensedFontMask + NSItalicFontMask 22 NSCondensedFontMask + NSBoldFontMask 6 NSCondensedFontMask + NSItalicFontMask + NSBoldFontMask 30 NSFixedPitchFontMask 11 NSFixedPitchFontMask + NSItalicFontMask 11 NSFixedPitchFontMask + NSBoldFontMask 5 NSFixedPitchFontMask + NSItalicFontMask + NSBoldFontMask I think you’re probably better off calling availableFontFamilies then iterating those with availableMembersOfFontFamily: and picking out the ones you want from there. That’s probably better anyway as it will give you all the font families which have both a plain and a bold option which sounds like what you might want. I’d try it out but I’ve exhausted my Swift-fu for the day. > On 31 May 2015, at 10:42, Graham Cox <graham....@bigpond.com> wrote: > > I’m using -[NSFontManager availableFontNamesWithTraits:] and I want to get > the names of all of the fonts that have both a regular (plain) and bold > option. > > I’ve tried various things, but this seems like it should work: > > NSArray* fonts = [[NSFontManager sharedFontManager] > availableFontNamesWithTraits:NSBoldFontMask | NSUnboldFontMask]; > > Except it returns no results.
