ios - GKAchievement reportAchievements 给出 NSIllegalArgumentException

Question

我在 GKTurnBasedMatch 中实现了 GKAchievement，它最初是有效的。现在我在为其他玩家报告成就时收到此错误。有趣的是，相同的代码将成就奖励给本地玩家

Terminating app due to uncaught exception 'GKInvalidArgumentException', reason: 'A GKAchievement can only be submitted for another player when ending a turn-based match.'

这是我用于报告 GKAchievement 的代码

GKAchievement *achievement = [[GKAchievement alloc] initWithIdentifier:identifier forPlayer:playerID];
if(achievement) {
    achievement.percentComplete = percent;
    achievement.showsCompletionBanner = YES;
    [GKAchievement reportAchievements:@[achievement]
                   withCompletionHandler:^(NSError *error) {
        if(error) {
            NSLog(@"Unable to report achievement: %@", error);
        }
        completion(nil);
    }];
}

这是结束 GKTurnBasedMatch 的代码

 [self.gkMatch endMatchInTurnWithMatchData:archivedData
              completionHandler:^(NSError *error) {
    if(!error) {
        NSLog(@"Awarding Achievement to %@", [self getWinner].log);
        NSString *winnerPlayerId = [self getWinner].playerId;
            [self awardAchievement:@"someAchievement" to:winnerPlayerId  percentCompleted:100.0 completion:^(NSError *error1) {
                completion(error1);
            }];
    } else {
        NSLog(@"endMatchInTurnWithMatchData %@", error);
    }
}];

在这方面帮助我。
谢谢。
