问题
I'm making a turn-based game, using the Game Center Turn-Based Gaming functionality. I'm using the simulator and my iPhone to test notifications of turn events. The results are very inconsistent. About 75% of the time when I make a move on the simulator and pass the turn I don't get any notifications on my iPhone. It seems that this function doesn't get called:
handleTurnEventForMatch:didBecomeActive:
I set the GKEventHandlerDelegate in the code that authenticates the local user and it seems to be set correctly. The fact that I get notifications once in a while suggests that this isn't where the problem lies.
Does anyone have any idea what could be the problem here? Could this be a problem with the Sandbox Game Center Server? Do they limit the amount of notifications you can send in a short amount of time or something like that?
Edit: I just found some posts of people experiencing the same problem, but no solution. No very recent posts though. Any updates?
Edit2: I also find that after a move, when I open the GKTurnBasedMatchmakerViewController on the other device it still says that it's the turn of the other player. When I close and reopen it the information is correct. Also, when I open the game GKTurnBasedMatchmakerViewController when it's still showing incorrect information, it does gives me the correct match object with the updated information. Could this be related in any way?

I thought I would share my solution with you, in the hopes that it is the same problem you are experiencing. As you can see from my comment to your question, I was having the same issue as you. It turned out that my settings in iTunes Connect were the culprit, unbeknownst to me. What you should check for is that you still have Game Center enabled in BOTH places that iTunes Connect requires. First, after going into "Manage my Apps" in iTunes Connect, select your app and on the right menu, and click "Manage Game Center". Make sure this is currently enabled. I would even recommend disabling it, and re-enabling it again for good measure.
In addition (and this is what I was missing), you must enable it in one more place. Go back to the previous screen when you first select the app. The top right is where you can select Manage Game Center, but we are looking on the bottom in the "Versions" section. Click the View Details button for your app, and make sure the Game Center button is enabled near the bottom. Again, I would disable and re-enable it here as well. Give it about 10 minutes, clear all your open turns and matches from the Game Center app (this might be an optional step), and build & run again. Hopefully, you will receive turn notifications properly again.
