I want to use the new iOS 7 Multipeer Connectivity in my app where one person is a host, and anyone can join the host.
I have successfully implemented it using a combination of this tutorial and the Apple Developer Reference to Multipeer Connectivity.
What I want to do however, is add an extra layer of security so not just everyone can join the app. I want it so when a person requests to join the host, they must enter a random 4 digit pin code which the host will tell the group so people who know it can type it in and join the session.
Is this possible to do? As iOS 7 is so new, it is hard to find andy information on it.
Any help or suggestions would be much appreciated. Cheers
