To show your Game center friends in your app you can use the below code given.

     -(void) retrieveFriends
   {
          GKLocalPlayer *lp = [GKLocalPlayer localPlayer]; 
          if (lp.authenticated)   
         { 
             [lp loadFriendsWithCompletionHandler:^(NSArray *friends, NSError *error)
             {
                 if (friends != nil)
                 {
                      [self loadPlayerData: friends];
                 }

             }];

         }

    }



       -(void) loadPlayerData: (NSArray *) identifiers
        {
             [GKPlayer loadPlayersForIdentifiers:identifiers withCompletionHandler:^(NSArray *players, NSError *error) 
           {

              if (error != nil) 
                {
                  // Handle the error.
                } 
             if (players != nil) 
               {
          // Process the array of GKPlayer objects.
               } 
           }];

          }
