Dear Cocoa-dev People,
First, I wanted to thank Aki Inoue and Rob Keniger for pointing out the problem
with my NSData->NSString->NSData approach.
As an alternative, would it be fruitful to use a Directory Wrapper to represent
the data as two files; one the metadata and the other the pdf? Then I could
work with the metadata file, but just display the pdf file.
In the "What could go wrong here?" department, would my compound file end up
behaving like a directory (or worse)?
Many thanks,
Joel Norvell
