GKMatchmakerViewController在iOS 7中不开放，但在iOS 5.1中工作

我遵循了本教程，但配对窗口没有打开。源代码的DropBox链接

如果我使用这个应用程序，那么它会在iOS 6及以上版本中崩溃，但会打开GKMatchmakerViewController

用户身份验证代码

- (void)authenticateLocalUser {

    if (!gameCenterAvailable) return;

    NSLog(@"Authenticating local user...");
    if ([GKLocalPlayer localPlayer].authenticated == NO) {
        [[GKLocalPlayer localPlayer] authenticateWithCompletionHandler:nil];
    } else {
        NSLog(@"Already authenticated!");
    }
}

几个月前我遇到了同样的问题，我解决这个问题的方法是将mmvc作为模态视图控制器。请尝试用以下内容替换您的else：

[presentingViewController dismissModalViewControllerAnimated:NO];
GKMatchRequest *request = [[[GKMatchRequest alloc] init] autorelease];
request.minPlayers = minPlayers;
request.maxPlayers = maxPlayers;
request.playersToInvite = pendingPlayersToInvite;

GKMatchmakerViewController *mmvc = [[[GKMatchmakerViewController alloc] initWithMatchRequest:request] autorelease];
mmvc.matchmakerDelegate = self;
[presentingViewController presentModalViewController:mmvc animated:YES];

self.pendingInvite = nil;
self.pendingPlayersToInvite = nil;

此外，您的身份验证似乎存在问题。您的方法应使用新的播放器身份验证机制，如：

- (void)authenticateLocalUser { 

    if (!gameCenterAvailable) return;

    NSLog(@"Authenticating local user...");
    if ([GKLocalPlayer localPlayer].authenticated == NO) {

        // Use new authentication mechanism if the iOS version is 6.0 or above
        if ([[UIDevice currentDevice].systemVersion compare:@"6.0" options:NSNumericSearch] != NSOrderedAscending) {
            [[GKLocalPlayer localPlayer] setAuthenticateHandler:^(UIViewController *vc, NSError *error) {
                if (error)
                    NSLog(@"Error in authenticating User - %@", [error localizedDescription]);
                else if (vc) {
                    AppDelegate *appDel = (AppDelegate *)[UIApplication sharedApplication].delegate;
                    [appDel.navigationController presentModalViewController:vc animated:YES];
                }
            }];
        }
        else
            [[GKLocalPlayer localPlayer] authenticateWithCompletionHandler:nil];
    }
    else {
        NSLog(@"Already authenticated!");
    }
}

调用此方法时，“gameCenterAvailable”中的值是多少？@nomanasim-我正在ios 7.0上测试它，以便gamecenter可用，并且在调试时，它正在输入其他部分。您的配对代码可能没有任何问题。我认为您在身份验证过程中失败了。你能粘贴你的“authenticateLocalUser”代码吗？@nomanasim-请查看我的更新问题我也共享了源代码正如我所怀疑的，你正在使用authenticateWithCompletionHandler进行身份验证，该身份验证在iOS 6.0之后被弃用并最终删除。因此，我认为您的播放器将无法在较新的iOS版本中获得身份验证。我已经用正确的方式更新了我的答案。@nomanasim-谢谢你的关心。但在appdelegatelet类型的对象上找不到属性navigationController时出错

- (void)authenticateLocalUser { 

    if (!gameCenterAvailable) return;

    NSLog(@"Authenticating local user...");
    if ([GKLocalPlayer localPlayer].authenticated == NO) {

        // Use new authentication mechanism if the iOS version is 6.0 or above
        if ([[UIDevice currentDevice].systemVersion compare:@"6.0" options:NSNumericSearch] != NSOrderedAscending) {
            [[GKLocalPlayer localPlayer] setAuthenticateHandler:^(UIViewController *vc, NSError *error) {
                if (error)
                    NSLog(@"Error in authenticating User - %@", [error localizedDescription]);
                else if (vc) {
                    AppDelegate *appDel = (AppDelegate *)[UIApplication sharedApplication].delegate;
                    [appDel.navigationController presentModalViewController:vc animated:YES];
                }
            }];
        }
        else
            [[GKLocalPlayer localPlayer] authenticateWithCompletionHandler:nil];
    }
    else {
        NSLog(@"Already authenticated!");
    }
}
