Ios 使用SLComposeViewController将图像发布到facebook的特定相册中

我正在使用以下代码在Facebook上发布图像

-(void) facebookShare: (id) sender
{
    if ([SLComposeViewController isAvailableForServiceType:SLServiceTypeFacebook])
    {
        SLComposeViewController *facebookSheet = [SLComposeViewController composeViewControllerForServiceType:SLServiceTypeFacebook];
        CCScene *myScene = [[CCDirector sharedDirector] runningScene];
        CCNode *node = [myScene.children objectAtIndex:0];
        [facebookSheet addImage: [GameOverLayer screenshotWithStartNode:node]];
        [facebookSheet setInitialText:[NSString stringWithFormat:@"I just scored %d in an awesome game of XXX", scoreNum]];
        [[CCDirector sharedDirector] presentViewController:facebookSheet animated:YES completion:nil];
    }
    else
    {
        UIAlertView *alert = [[UIAlertView alloc] initWithTitle: @"Please login to Facebook to share your score!" delegate: self cancelButtonTitle:@"Cancel" otherButtonTitles:@"Login",nil];
        [alert show];
    }    
}

代码运行良好，但我想知道如何为游戏创建特定的相册，并将图像发布到该相册中？谢谢
