Question

I am new to iOS development and I recently came to know about the Apple Push Notification Service.

Does anyone know whether it is possible to push application updates to iPhone/iPad devices using Apple Push Notification Service..?

Thanks.

Answer 1

From the documentation:

Local notifications and push notifications are ways for an application
that isn’t running in the foreground to let its users know it has
information for them. The information could be a message, an impending
calendar event, or new data on a remote server. When presented by the
operating system, local and push notifications look and sound the
same. They can display an alert message or they can badge the
application icon. They can also play a sound when the alert or badge
number is shown.

So no, you can’t push application updates. You could send a message telling the user that an update was available, though that would be considered pretty obnoxious by many users.
