I have a problem with IOS push notification. I am using php(Zend) as a provider. I have tested the notification in below scenarios:
1) Installed app in my iPhone and sends the device token to server and it is successfully stored in database. Then i have fired a notification, and i have received notification.
2) Then i have uninstalled the app from device and fired a notification. In this scenario APNS doesn't returned any error message. Feedback service also not gave any invalid tokens (Device has other apps which has push notification enabled).
3) Installed app again then send the notification. Now, The notification is successfully sent.
So my question is, why apns not returned invalid token when app is uninstalled from the device. Why feedback service not returned any invalid tokens?
Thanks in advance
