GKMatchmakerViewController委托方法未被调用

Question

我花了几个小时试图调试这个，所以我想我应该在这里发帖，也许可以帮别人省去头疼的事！

GKMatchRequest *matchRequest = [[GKMatchRequest alloc] init];
matchRequest.minPlayers = 2;
matchRequest.maxPlayers = 2;
GKMatchmakerViewController *controller = [[GKMatchmakerViewController alloc] initWithMatchRequest:matchRequest];
controller.delegate = self;

Answer 1

解决方案是我忽略了控制器委托不是要设置的正确委托这一事实！使用matherDelegate，一切都会好起来的！

controller.matchmakerDelegate = self;
