title: IOS Game center match making
body: <p>I am working on a turn based game with game center. I researched patiently the following problem, but i hope someone comes with a solution.</p>
  
  <p>I start an auto-match game with a certain map, i would like to connect to only the players whom selected the same map to play. Is there any way to restrict that ? </p>
  
  <p>Thank you.</p>
