I've got a database who store the device Token, country Code and language of my users and I need to send remote notifications for all the user. What kind of tool can I used to send all notifications by country with a batch?
Thanks,
It's not quite clear what exactly you are trying to achieve but here are options based on my guess, ordered by relevance:
In terms of notifications you can use:
Apple Push Notification Service
Local notifications (some relevant info)
If you want updates to be invisible to user and just update app you should employ NSURLSession and NSURLConnection and work up from there. These might be of interest:
Polling updates on behalf of app with background fetches
Keeping connection open (search "ios SocketRocket" for example implementation)
And then there is oportunity to missuse Voice push API in a interesting way
