Canon raw files and jpeg files include a value of macro magnification encoded in the files. Exiftool can extract this information, but it apparently is not in plain text EXIF data. I would like to access this particular piece of data in an iOS app. Is there a simple way I can search the data to find the value? Alternatively, is there an exiftool framework available for iOS development that already does this?

The quick answer is "no".  Parsing the maker notes to extract this information is not simple.

Alternatively, if you can run Perl on iOS, then you can run ExifTool too.
