This is what I finally figured out. Here is the correct mapping from Mac to iOS for Helvetica Neue: Say you have a field in your Mac application which has the textfont set to "Helvetica Neue Thin". To properly display, you'll need to set the same field's textfont in iOS to "HelveticaNeue-Thin".
Here are all the iOS equivalents:
HelveticaNeue-UltraLight
HelveticaNeue-Thin
HelveticaNeue-Light
HelveticaNeue
HelveticaNeue-Medium
HelveticaNeue-Bold
HelveticaNeue-Bold Condensed
HelveticaNeue-Black Condensed
And unless anyone knows of a better way, here is some code to update all those fields on all those cards when in iOS:
Code: Select all
on altUpdateFontsFor_iOS
   lock screen
   lock messages
   repeat with x=1 to the number of cards in this stack
      repeat with y=1 to the number of controls on card x
         try
            get the textfont of control y of cd x
            if it contains "Helvetica" and the environment is "mobile" then
               set the textfont of control y of cd x to fixHelvetica(it)
            end if
         end try
      end repeat
   end repeat
   unlock messages
   unlock screen
end altUpdateFontsFor_iOS
private function fixHelvetica pFontname
   --> Helvetica Neue Thin BECOMES HelveticaNeue-Thin
   put "-" into char 15 in pFontname
   delete character 10 in pFontname
   return pFontname
end fixHelveticaCode: Select all
if the environment is "mobile" then altUpdateFontsFor_iOS
