How to detect user uninstalled iOS App? I need push serious notification. I don't wanna lose it

APNS has a feedback service where Apple reports any device token that is no longer active on the users device. You are required by Apple to check the tokens from the feedback service and stop sending pushes to those devices.

You can use this same information to automatically move the user back to SMS. Just tie the device token to the phone number in your database. If the token is active, send pushes to it. If it is reported by the feedback service to be in-active, remove it from your records and use the users phone number for SMS again.

Just remember that a device token can become active again, at which point, it will be registered with you through the same mechanism it was the first time. Re-save it with the user and use push again.

Ideally, there would be a delegate method called before the app is deleted, but currently there is not, as there is no way to track an app that is not running. You could run .unauth() in the applicationWillTerminate in the App Delegate file, but that would log the user out every time the app is killed.

Why do you need to log out the user? There are a few options to simulate this.
