Push messaging

Hi, has anyone intergrated push messaging directly into an app? Is there some kind of example? Is this easy to do? I’ve found a nice example of a combined PHP > ios app, but not OFx:

Hi,

I’m curious too if anyone has implemented push messaging in OF yet as it would be a great way to keep in touch with users!

If anyone does actually implement this, please be respectful. The only time I want an app to push a message to me is if it’s alerting me to e.g. my turn in a game.
