iphone - Is there way in iOS to receive notification that a keychain entry has changed? -


is there way in ios receive notification keychain entry has changed?

i've seen in os x there seckeychaincallback mechanism there no indication such event-callback paradigm exists iphone.

we using keychain pass token data between ios apps, , if app receive notification if data has changed, without continuously checking it.

unfortunately isn't possible, keychain services on ios barebones, , provide simple apis accessing/storing items. , because it's c based, won't able piggyback on sort of kvo either.

you need poll @ appropriate intervals.
