ios - Will push token change when app is rebuilt? -


i'm planing rebuild 1 of applications(new xcode project), heavily relay on push notifications.

will push token change after update installed?

i need notifications work if user doesn't open new app after update.

what mean rebuild? tokens don't change every time app rebuilt.

the tokens can change unfrequent when do, when not documented apple, have noticed occur if backup restore app itunes 1 example.

however system should designed cope them changing - client code should token each time launches , compare cached version, , if differ must send new 1 server. if app doesn't have cached 1 send retrieved 1 server.
