游戏中心以编程方式邀请朋友 [英] Game Center inviting friends programmatically

问题描述

我很难邀请一位朋友参加比赛.

GKMatchRequest *request = [[[GKMatchRequest alloc] init] autorelease]; 
    request.minPlayers = 2;
    request.maxPlayers = 2;
    request.playersToInvite = [NSArray arrayWithObjects: @"G:1102359306",nil ];


//  GKMatchmakerViewController *mv = [[GKMatchmakerViewController alloc] initWithMatchRequest:request];
//  [self presentModalViewController:mv animated:YES];


    [[GKMatchmaker sharedMatchmaker] findMatchForRequest:request withCompletionHandler:^(GKMatch *match, NSError *error) {
        if (error) {
            NSLog([error description]);
        }
        else if (match != nil) {NSLog(@"good match");
            //self.chatMatch = match;
            //self.chatMatch.delegate = self;       
            //[self chatReady];
        }
        else {
            NSLog(@"other error");
        }

    }];

问题是我从未在登录到该帐户的第二台设备上收到邀请通知-G:1102359306. 当我使用GKMatchmakerViewController(在2行以上未注释)并注释GKMatchmaker块时，我自动检查了好朋友-G:1102359306，当我邀请他时显示了带有接受/拒绝的通知，这就是我所知的正确方法.

您发现上面的代码有什么问题吗?我想使用自己的UI来处理多人游戏模式.奇怪的问题是，在控制台中我也看不到任何匹配或其他错误的日志，并且仅当我两次调用上述代码时才显示[错误描述]-它表示先前的要求已被取消.

解决方案

您不能以编程方式邀请一组特定的球员参加比赛. findMatchForRequest:withCompletionHandler:文档这样说:

匹配请求的playersToInvite属性将被忽略；要邀请一组特定的玩家参加比赛，您必须显示一个媒人视图控制器.

没有公共API可以满足您的要求.

I'm facing difficulty inviting a friend to the match.

GKMatchRequest *request = [[[GKMatchRequest alloc] init] autorelease]; 
    request.minPlayers = 2;
    request.maxPlayers = 2;
    request.playersToInvite = [NSArray arrayWithObjects: @"G:1102359306",nil ];


//  GKMatchmakerViewController *mv = [[GKMatchmakerViewController alloc] initWithMatchRequest:request];
//  [self presentModalViewController:mv animated:YES];


    [[GKMatchmaker sharedMatchmaker] findMatchForRequest:request withCompletionHandler:^(GKMatch *match, NSError *error) {
        if (error) {
            NSLog([error description]);
        }
        else if (match != nil) {NSLog(@"good match");
            //self.chatMatch = match;
            //self.chatMatch.delegate = self;       
            //[self chatReady];
        }
        else {
            NSLog(@"other error");
        }

    }];

The problem is I never receive the invitation notification on second device logged to the account - G:1102359306. When I use GKMatchmakerViewController (uncomment above 2 lines) and comment GKMatchmaker block I have automatically checked the good friend - G:1102359306 and when I invites him the notification with accept/decline is shown, that's how I know it's correct.

Do you see anything wrong with the code above? I want to use my own UI to handle the multiplayer mode. The strange problem is I also don't see in console any logs good match/other error, and the [error description] is only printed when I call the above code twice - it says that the previous req was canceled.

解决方案

You cannot programmatically invite a specific set of players to a match. The findMatchForRequest:withCompletionHandler: documentation says this:

The match request’s playersToInvite property is ignored; to invite a specific set of players to the match, you must display a matchmaker view controller.

There is no public API that does what you want.
