Since you can't have an iOS app that continuously checks Facebook in the background and since you can't bring Facebook to send a push notification to your app, you would have to set up a web server that continuously polls Facebook for changes and then sends a push notification to the iOS device when it detects a change.

I know this is an old question, but if you want to push changes in facebook to somewhere it might be a good idea to look into the Facebook Realtime Updates API. As it notifies directly of any changes in facebook you've subscribed to.
