ios - Game Center : match delegate’s not called after finding a match -

-

i'm trying use game center : multi player

till now, players authenticating game center, can send/read scores, , acheivements. multiplayer features, tried both methods : - using game center interface find match. - find match programmatically.

for both ways have following issue: match delegate’s match:player:didchangestate: method not called. in apple docs, it's stated delegate called if 1 player connected or disconnected.

in case delegate never called. think i'm missing step. here after implementation of delegate (as specified in apple doc).

- (void)match:(gkmatch *)match player:(nsstring *)playerid didchangestate:(gkplayerconnectionstate)state {     switch (state)     {         case gkplayerstateconnected:             // handle new player connection.            break;         case gkplayerstatedisconnected:             // player disconnected.            break;     }     if (!self.matchstarted && match.expectedplayercount == 0)     {         self.matchstarted = yes;         // handle initial match negotiation.     } }

and code find match.

-(void) findprogrammaticmatch {   gkmatchrequest *request = [[[gkmatchrequest alloc] init] autorelease];   request.minplayers = 2;   request.maxplayers = 2;    [[gkmatchmaker sharedmatchmaker] findmatchforrequest:request                                  withcompletionhandler:^(gkmatch *foundmatch, nserror *error)   {     if (error)     {       // process error.       statuslabel.text = @"match not found";     }     else if (foundmatch != nil)     {       multiplayermatch = foundmatch; // use retaining property retain match.       statuslabel.text = @"match found";       multiplayermatch.delegate = self; // start!       // start match.       // start game using match.       [self startmatch];     }   }]; }

thanks help.

it working along. difference that... when use invites event "didchangestate" doesn't called. you're connected without notice , can start receive data. never tried send/receive data because expecting event first, did send mistake 1 time, , worked.

- (void)matchmakerviewcontroller:(gkmatchmakerviewcontroller *)viewcontroller didfindmatch:(gkmatch *) match {         //dismiss window     [self dismissmodalviewcontrolleranimated:yes];      //retain match     self.mymatch = match;       //delegate     mymatch.delegate = self;       //flag     matchstarted = true;     //other stuff }  - (void)match:(gkmatch *)match player:(nsstring *)playerid didchangestate:(gkplayerconnectionstate)state  {     //this code gets called on auto-match }

the above code works expected.
