The error appear after coding the match game

I just finish code with the video yesterday, and I have the following error reports

the first message is [plugin] AddInstanceForFactory: No factory registered for id

then if I click cards continuously, I got the error: [aqsrv] AQServer.cpp:68:APIResult: Exception caught in AudioQueueInternalNotifyRunning

are you using a real device to test?.. it seems that it might be an issue with the simulator
