Communication between two iOS devices

Question

I am looking for a way to have one iPhone app send a message to another app on a different phone (sort of like a Sender-Receiver set up). I am looking for the best possible way to do this. Does anyone have any ideas and/or tutorials?

Thanks for the help.

Answer 1

You should use GameKit. It is super easy to send messages between two iOS devices using it. Here's a great tutorial: Game Kit. You can also get more information about it here from the docs: About Game Kit.

You communicate by creating an ad-hoc bluetooth or local wireless network.

Answer 2

lmirak provided insightful info about device communication(especially about GameKit). I would like to add one more solution. You can use WiFi network to do your device communication.

See the link or download the sample application from developer.apple

The sample application named as WiTap. It demonstrates how to achieve network communication between applications. Using Bonjour, the application both advertises itself on the local network and displays a list of other instances of this application on the network.
