Is there a way to perform async communication between iPhones/IOS devices? I have been researching and thought maybe APN might fill that void, but it sounds like I can’t initiate an APN push from an IOS dvice to another, and even if I could I can’t trigger the “event” on the other device with just an APN push from what I can identify.
Does anyone have any examples or general advice for IOS device interaction for devices that are not in GameKit (i.e. wifi/bluetooth) range that does not require an intermediate service (urban airship, dedicated server, etc) or will I need to have a 3rd party in order to trigger and/or sync these interactions between devices?
Sorry I don’t have any code or details as this is still in the planning phases for me. Any pointers would be greatly appreciated.
The answer is : use a server side app and have all your devices talk to that server.
If you dont want or cannot host an app, you can use a cloud solution based on websocket like Pusher. You can then subscribe to events and post messages with data.
They have an iOS client library

P.S: Also have a look at Parse and Stackmob , i remember that had this kind of feature was in their roadmap, but i don’t know if it’s available yet..
Hope this helps,
