观看视频广告后在屏幕上更新分数

Question

我有两个场景GameScene和BonusScene我用NSUserDefaults保存中奖次数，一切正常，我添加了视频奖励广告，看完视频，你得到5分，这也有效，但屏幕上的分数更新仅在您转到不同场景并返回时发生，但是当我使用 NSLog() 时，我看到发生了更新，但我不知道如何在屏幕上实时进行. 这是我得到的：

    losingCount=[scoreprefs integerForKey:@"losingCount"];
    SKLabelNode *winsCoutnt = [SKLabelNode labelNodeWithFontNamed:@"ROTORcap Extended Bold"];
    winsCoutnt.text =[NSString stringWithFormat:@"%ld",(long)losingCount];
    winsCoutnt.position = CGPointMake(CGRectGetMidX(self.frame) + 100,(CGRectGetMidY(self.frame)) + self.frame.size.height/4 );
    winsCoutnt.fontSize = 15.f;
    [self addChild:winsCoutnt];



 if([Chartboost hasRewardedVideo:@"NetworkVideo"] == YES) {

            NSUserDefaults *scoreprefs = [NSUserDefaults standardUserDefaults];

            losingCount =[scoreprefs integerForKey:@"losingCount"];
            losingCount = losingCount +5;
            [scoreprefs setInteger:losingCount forKey:@"losingCount"]; }

所以我的问题是如何在屏幕上实时更新场景中的乐谱，而不用去不同的场景再回来？

只需更新您要更新 NSUserDefaults 的文本

    losingCount=[scoreprefs integerForKey:@"losingCount"];
SKLabelNode *winsCoutnt = [SKLabelNode labelNodeWithFontNamed:@"ROTORcap Extended Bold"];
winsCoutnt.text =[NSString stringWithFormat:@"%ld",(long)losingCount];
winsCoutnt.position = CGPointMake(CGRectGetMidX(self.frame) + 100,(CGRectGetMidY(self.frame)) + self.frame.size.height/4 );
winsCoutnt.fontSize = 15.f;
[self addChild:winsCoutnt];



if([Chartboost hasRewardedVideo:@"NetworkVideo"] == YES) {

        NSUserDefaults *scoreprefs = [NSUserDefaults standardUserDefaults];

        losingCount =[scoreprefs integerForKey:@"losingCount"];
        losingCount = losingCount +5;
        [scoreprefs setInteger:losingCount forKey:@"losingCount"]; 

        winsCoutnt.text =[NSString stringWithFormat:@"%ld",(long)losingCount];
}
