Question

在他们的支持中OpenFeint给你这个，但我不太明白。我怎样才能获得排行榜数据，比如前10名并在我自己的用户界面中显示？

[OFHighScoreService getPage:1 forLeaderboard:@"leaderboard_id_string" friendsOnly:NO silently:YES onSuccess:OFDelegate(self, @selector(_scoresDownloaded:)) onFailure:OFDelegate(self, @selector(_failedDownloadingScores))];

- (void)_scoresDownloaded:(OFPaginatedSeries*)page
{
    NSMutableArray* highscores = nil;

    if ([page count] > 0)
    {
        if ([[page objectAtIndex:0] isKindOfClass:[OFTableSectionDescription class]])
        {
            // NOTE: In the following line, we access "[page objectAtIndex:1]" to retrieve high scores from
            // the global leaderboard.  Using "[page objectAtIndex:0]" would retrieve scores just for the local player.
            // Older versions of OpenFeint did not break this out into 2 sections.
            highscores = [(OFTableSectionDescription*)[page objectAtIndex:1] page].objects;
        }
        else
        {
            highscores = page.objects;
        }
    }

    for (OFHighScore* score in highscores)
    {
        // ...
    }
}
- (BOOL)canReceiveCallbacksNow
{
    return YES;
}

请求高分页面的代码是第一行，即：

[OFHighScoreService getPage:1 forLeaderboard:@"leaderboard_id_string" friendsOnly:NO silently:YES onSuccess:OFDelegate(self, @selector(_scoresDownloaded:)) onFailure:OFDelegate(self, @selector(_failedDownloadingScores))];

您将此行放在要开始查询以获得高分的位置。您可以根据需要更改页码。一旦检索到高分页面，就会调用回调_scoresDownloaded。该示例显示了如何遍历OFHighScore数组中的highscores个对象。您可以使用自己的代码替换评论// ...，以向玩家显示分数，或者其他任何内容。

（如果调用错误_failedDownloadingScores;您应该实现它以显示错误。）

如何从OpenFeint获得高分？
