这是我的编码,我用它来获得本地前10名的高分,但出现了调试终止错误Iphone 如何从openfeint获得本地前10高分,iphone,cocos2d-iphone,openfeint,Iphone,Cocos2d Iphone,Openfeint,这是我的编码,我用它来获得本地前10名的高分,但出现了调试终止错误 [OFHighScoreService getPageWithLoggedInUserForLeaderboard: theLeaderboardID onSuccess:OFDelegate(self, @selector(_scoresDownloaded:)) onFailure:OFDelegate()]; 选择器:- - (void)_scoresDownloaded:(OFPaginatedSeri
[OFHighScoreService getPageWithLoggedInUserForLeaderboard: theLeaderboardID onSuccess:OFDelegate(self, @selector(_scoresDownloaded:))

选择器:-
- (void)_scoresDownloaded:(OFPaginatedSeries*)page
{
NSMutableArray* highscores = nil;
if ([page count] > 0)
{
if ([[page objectAtIndex:0] isKindOfClass:[OFTableSectionDescription class]])
{
highscores = [(OFTableSectionDescription*)[page objectAtIndex:0] page].objects;
}
else
{
highscores = page.objects;
}
}
NSString *userID = [OpenFeint lastLoggedInUserName];
for (OFHighScore* score in highscores)
{
ccColor3B theColor = ccBLACK;
if ([score.user.name isEqualToString: userID] ) {
//score now contains the users data... Do what I want with it.
NSLog(@"%d %@ %d", score.rank, score.user.name, score.score);
break;
}
}
}
这是我的控制台窗口错误:-
*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[Levelone canReceiveCallbacksNow]: unrecognized selector sent to instance 0x6af2070'
*** Call stack at first throw:
terminate called after throwing an instance of 'NSException'
正如错误所述,您用作HighScoreService的
回调委托的对象无法识别选择器canReceiveCallbacksNow
。根据OpenFeint文档,回调必须实现可调用的协议,该协议定义了这一点。只需实现该功能,例如,让它始终返回YES
。OpenFeint仅在给定排行榜上存储每位玩家的最新排位赛分数。任何用户都不会在排行榜上排名超过一位。非常感谢您的帮助。但本地设备的得分只有一分(前1名)。我想要本地设备播放器的前10名,有什么问题吗?但是本地设备只有一分(前1名)。我想要本地设备播放器的前10名,有什么问题吗
