how can I go about decoding NSAttributedString
I just tried in a playground, and the problem is in NSParagraphStyle, not
NSAttributedString. It looks like it falls foul of the known secure coding
issue about
decoding arrays of unknown type. (NSTextTab is the only class that lives in an
array
within a paragraph style.)
That means NSParagraphStyle doesn’t actually conform to NSSecureCoding, and
therefore
nor does NSAttributedString, when any non-default tabs are present. It’s not
clear that
there’s an easy workaround. The only thing I can think of is to archive the
text tabs
separately, and somehow re-install them on the relevant paragraph styles after
decoding, but that’s going to be a huge PITA in general.
Thanks Quincey, that's in fact a huge problem. Even if I find a way to write the thing so
it can be read back, I still have old files to read that contain offending
NSAttributedStrings.
The string is just a tiny part of my huge model, so I need a way to read it back, if need
be without formatting. The one thing that it can't do is prevent me from reading files
containing it.
Best Regards
Markus
