OpenFeint 成就百分比增量

我正在制作一个启用 OpenFeint 的 iOS 应用程序。我已经成功地实现了除一项成就之外的所有成就。这项成就是部分完成的。

我的具体问题是我还没有找到一个可行的解决方案来将 1% 添加到当前的成就百分比。

我找到了这个值（它应该是一个double）：

double achievement12 = [OFAchievementService getPercentComplete:ach12Id 
                                                        forUser:[OpenFeint lastLoggedInUserID]];

但这会导致以下错误和警告：

“无法在初始化时将 'objc_object*' 转换为 'double'。
“OpenFeint”可能不会响应“+lastLoggedInUserId”
“OFAchievementService”可能不会响应“+getPercentComplete:forUser:”

实际的功能代码是：

    // Note: this should be moved into public API
   + (double) getPercentComplete:(NSString*)achievementId forUser:(NSString*)userId
    {
        sAlreadyAtLeastPartlyCompleteQuery.bind("achievement_definition_id", achievementId);
        sAlreadyAtLeastPartlyCompleteQuery.bind("user_id", userId);     
        sAlreadyAtLeastPartlyCompleteQuery.execute();
        float percentComplete = (double)    (sAlreadyAtLeastPartlyCompleteQuery.getDouble("percent_complete"));
    sAlreadyAtLeastPartlyCompleteQuery.resetQuery();
    return percentComplete;
    }

这是最后一件事我必须在这个应用程序上做一些事情，它已经困扰我几天了。

I'm making an iOS app which is OpenFeint enabled.
I have managed to get all but one achievement to work. This one achievement is a partially completed one.

My specific problem is that I haven't found a working solution to add 1% to the current achievement percentage.

I found this value (it's supposed to be a double):

double achievement12 = [OFAchievementService getPercentComplete:ach12Id 
                                                        forUser:[OpenFeint lastLoggedInUserID]];

but this causes the following errors and warnings:

"Cannot convert 'objc_object*' to 'double' in initialization.
'OpenFeint' may not respond to "+lastLoggedInUserId"
'OFAchievementService' may not respond to "+getPercentComplete:forUser:"

The actual function code is:

    // Note: this should be moved into public API
   + (double) getPercentComplete:(NSString*)achievementId forUser:(NSString*)userId
    {
        sAlreadyAtLeastPartlyCompleteQuery.bind("achievement_definition_id", achievementId);
        sAlreadyAtLeastPartlyCompleteQuery.bind("user_id", userId);     
        sAlreadyAtLeastPartlyCompleteQuery.execute();
        float percentComplete = (double)    (sAlreadyAtLeastPartlyCompleteQuery.getDouble("percent_complete"));
    sAlreadyAtLeastPartlyCompleteQuery.resetQuery();
    return percentComplete;
    }

This is the last thing I have to do on this app, and it has been bugging me for a few days now.
