I originally used http://www.easyapns.com/ as a guide for building my backend and sending push notifications. However I quickly realized that this no longer works, and I'd love to find another solution that works similar.
Essentially I need to store the device and tokens on my backend, and send out push notifications to certain devices in the DB.
Any help is GREATLY appreciated
Thanks
If it's your only requirement, there are many services to do this without creating specific backend, like pusher, push robot, google push notification service, etc.... All take care of registration of the token.
If you need to create a specific backend, then it depends of the others requirements, but Web and Github are full of examples on this topic.
