objective c - Get notified when NSDocument is saved -

how can notified when nsdocument saved, first time , subsequent times?

i first thought overriding writetourl:oftype:error: it, appears method called temporary autosaves before document saved first time, , maybe on copy/duplicate operations.

on other hand, setfileurl: appears called first time document saved not on subsequent times.

is there kind of save notification? or have work around various border cases of above methods?

nsdocument has writesafelytourl::::, in add-on target location url gets nssaveoperationtype passed in. allow filter out autosave operations.

don't forget phone call super implementation when overriding writesafelytourl.
