ios - Decrement GKScore value

Question

When I try to store score value less than current value, it doesn't get stored. Any help please?

GKScore *scoreReporter = [[GKScore alloc] initWithCategory:@"top_matcher"];
scoreReporter.value = currentScore - 10;
[scoreReporter reportScoreWithCompletionHandler:^(NSError *error) {
  NSLog(@"ERROR:%@ %lld %@", error, score, scoreReporter);
}];

Answer 1

您不能降低分数（如果您的排行榜首先设置为最高），一旦您发布它，它就在那里。

Answer 2

如果您想显示所有乐谱，您必须在 iTunes Connect 上将乐谱提交类型设置为“最新乐谱”。这会将所有分数提交到您的排行榜。在检索排行榜的分数时，如果您需要该功能，您可以自己按“值降序”对它们进行排序。

[myLeaderboard loadScoresWithCompletionHandler: ^(NSArray *scores, NSError *error) {
    NSSortDescriptor *descriptor = [NSSortDescriptor sortDescriptorWithKey: @"value" ascending: NO];
    NSArray *sortedScores = [scores sortedArrayUsingDescriptors: @[descriptor]];        
    }];
