将 NSFont 存储到文档中

Question

Our picture editing cocoa application allows the user to add a string to a photo. This string has an associated NSFont object. We want to store this NSFont object in the saved document. Is using archiving NSFont using NSCoding the best way around?

Answer 1

I would have thought you would be better off storing an NSFontDescriptor , since that way you have more control over exactly which font you use when your editing app finds itself opening a file on a machine that doesn't have the font that was used when the file was saved.
