any option to know if apple app get the push notification?

Question

I build xcode app that get push notification, the main problem is that the push notification is very critical for me. so I want to check if the push notification is delivered to the device with the app installed, I understand that if the iphone dosn't have internet connecction / 3G the push notification is not getting to the device.

how can I check if the device get the notification or not? how can I check if the APNS successful to deliver the push notification?

I want to send sms if the push notification is not deliver to the device so I think about the idea to get the notification event when it's open by the push notification, and to send request to my server so i can know if the push notification is successful deliver or not. the main problem is that the user need to open the app every time he get the notification and in the night it's a problem. so this option is not good for me.

I check the feedback server push notification but i don't find any info that I can get if the push notification is delivered or not

any idea??

Answer 1

With iOS7 you have a new method called application:didReceiveRemoteNotification:fetchCompletionHandler: which you probably could use for your task. From Apple's Docs:

Implement this method if your app supports the remote-notification background mode. ... When a push notification arrives, the system displays the notification to the user and launches the app in the background (if needed) so that it can call this method. Use this method to download any data related to the push notification. When your method is done, call the block in the handler parameter.

Unlike the application:didReceiveRemoteNotification: method, which is called only when your app is running, the system calls this method regardless of the state of your app.

The short answer, you can't, since APNS is one way. However, since an app can execute arbitrary code upon receipt of a notification, you can use this to say, send an http request to your own server when the notification is recieved.
