Save received remote push notifications - ios

Can we save the received push notifications locally in a plist?

I have a reqiurment to show the number of unread push notifications in a badge view just like applicationIconBadgeNumber. But it should be shown inside the application, not as the icon badge view.

So, my question is can we save the received push notifications in all the status of the application(running, background and quit)?

I have implemented the push notifications, I can share the code if its necessary
