我正在尝试使用游戏中心以编程方式创建实时多人游戏。我的问题是缺少文档，因为旧inviteHandler版本已被弃用。
我做的第一件事是身份验证：
- (void) authenticateLocalPlayer
{
GKLocalPlayer *localPlayer = [GKLocalPlayer localPlayer];
__weak GKLocalPlayer *blockLocalPlayer = localPlayer;
localPlayer.authenticateHandler = ^(UIViewController *receivedViewController, NSError *error)
{
if (receivedViewController != nil)
{
[self presentViewController:receivedViewController animated:YES completion:nil];
}
else if (blockLocalPlayer.isAuthenticated)
{
[blockLocalPlayer registerListener:self];
}
};
}
之后，我按照苹果文档上的说明开始邀请过程。
- (void)invitePlayers:(NSArray *)friendsArray
{
GKMatchRequest *request = [[GKMatchRequest alloc] init];
request.minPlayers = 2;
request.maxPlayers = 2;
request.playersToInvite = friendsArray;
request.inviteMessage = @"Your Custom Invitation Message Here";
request.inviteeResponseHandler = ^(NSString *playerID, GKInviteeResponse response)
{
[self updateUIForPlayer: playerID accepted: (response == GKInviteeResponseAccepted)];
};
}
我实现了以下方法，但它们从未被调用：
- (void)player:(GKPlayer *)player didAcceptInvite:(GKInvite *)invite
- (void)player:(GKPlayer *)player didRequestMatchWithPlayers:(NSArray *)playerIDsToInvite
如何让其他玩家收到邀请并做出回应？在苹果文档中，演示了不推荐使用的旧方式。
