ios - ALAssetRepresentation URL 'persistence' lifetime? -


quick question: how long alassetrepresentation url (its 'url' property) guaranteed point same asset?

the documentation describes 'persistent' mean persistent on single sync, persistent until new photos added, persistent until old photos deleted, or what? if build database associates photo elements in camera roll/photo library data in application using alassetrepresentation url's, these associations continue work forever, if photos moved or renamed?

from observations, if delete photos/videos camera roll, 1000000007, assuming current last id 1000000008, next saved item not reuse identifier, rather 1000000009. however, if last image deleted (1000000008) reuse one.

basically picks highest unused identifier number, if delete items using less current highest identifier, not "fill-in" old identifiers.

this photos in camera roll. i'm not sure other alassetgroups.
