objective c - Difference between CoreData sqllite file size with images stored in it and total iCloud space -

-

i have decided give try saving images coredata binary. small images 2k 90k maximum, , can have trashed many lines of code, ones dealing icloud issues.

considering coredata storage put in icloud using properties such nspersistentstoreubiquitouscontentnamekey, have noticed sqlite file 1.6mb in size. while total icloud space occupied application itself, seen in ios settings, 34mb, , not have other documents around.

i put nssqlitemanualvacuumoption option, wondering causing space taken. transaction log ?

you should using external data references.

with each change entity stores images writing out of image data. external data references, image data stored separate file, , can deleted once no longer referenced.
