标题: ios - "A GKScore must specify a leaderboard."

有没有人在尝试将 Game Center 集成到 iOS 7 应用程序时遇到此错误？

A GKScore must specify a leaderboard.

这是失败的代码:

if(points > 0)
{
    //Fails on the next line
    [self.gameCenterManager reportScore:points forCategory:self.currentLeaderBoard];
}
GKLeaderboardViewController *leaderboardController = [[GKLeaderboardViewController alloc] init];
if (leaderboardController != NULL) {
    leaderboardController.category = self.currentLeaderBoard;
    leaderboardController.timeScope = GKLeaderboardTimeScopeWeek; 
    leaderboardController.leaderboardDelegate = self;
    [self presentViewController:leaderboardController animated:YES completion:nil];
}

更新我尝试了另一种方法，但仍然遇到同样的错误。

其他方法:

GKScore *scoreReporter = [[GKScore alloc] initWithCategory:self.currentLeaderBoard];
scoreReporter.value = points;

[scoreReporter reportScoreWithCompletionHandler:^(NSError *error) {
    if (error != nil)
    {
        [self showAlert"Game Center Error" theMessage"There was a problem uploading your score to Game Center, if this problem persists, please contact JApp Design." alertTag:0];
    }
}];

有什么想法吗？

Best Answer-推荐答案

我和你有同样的问题，但我解决了我的问题..

这是我的原始代码。

GKScore *scoreReporter = [[GKScore alloc] initWithLeaderboardIdentifier: identifier];
scoreReporter.value = score;
scoreReporter.context = 0;
scoreReporter.shouldSetDefaultLeaderboard = YES;
NSArray *scores = @[scoreReporter];

[GKScore reportScores:scores withCompletionHandler:^(NSError *error) {
    //Do something interesting here.
    [self callDelegateOnMainThread: @selector(scoreReported withArg: NULL error: error];
}];

从这里，我删除了这条线。 scoreReporter.shouldSetDefaultLeaderboard = YES 所以它工作得很好。
