Can I free use tahoma font in app development?
回答1:
Tahoma is not one of the fonts included on the iPhone or iPad (see here for a list). There are ways to bundle a font with your app, but you'd have to have an appropriate license to do so. As a workaround, it may be allowed to include pre-rendered graphic files with your app that use Tahoma.
(per your previous question: Tahoma may show up in the font picker in Interface Builder, but that's just the standard system-wide font picker, and all it indicates is that you have Tahoma installed on your Mac)
回答2:
Well the typography FAQ from microsoft says that
"You are not allowed to copy, redistribute or reverse engineer the font files"
A number of Microsoft fonts are now available to end users, ISVs and OEMs under license from Ascender Corporation. These include 'Verdana', 'Georgia', 'Comic Sans MS', 'Microsoft Sans Serif', 'Nina', 'Tahoma', 'Wingdings', 'Webdings' and 'Trebuchet MS'.
from what i understand you are supposed to buy a license from Ascender Corp. if you want to use them in your product.
