我正在制作各种记分牌。玩家可以调整三个不同的值（装备、等级和奖励），添加这些值后应提供总强度。这些值中的每一个当前都作为整数输出，并且 UILabel 显示其各自的整数。我不知道如何添加所有三个整数，然后将它们显示在 UILabel 上。我目前正在为 iOS 7 开发，但我不认为这对于当前支持的操作系统会有很大的不同。任何帮助是极大的赞赏。

创建某种updateScore在其他值之一发生变化时调用的方法。

- (void)updateScore {
    totalScoreCount = ... // calculate score from levelCount, gearCount, and oneShotCount

    self.totalScore.text = [NSString stringWithFormat:@"%i", totalScoreCount];
}

然后在您调用的每个...UpButton:和方法中：...DownButton:

[self updateScore];

请务必先更新其他值后调用它。例子：

- (IBAction)levelUpButton:(id)sender {
    levelCount = levelCount + 1;
    self.levelNumber.text = [NSString stringWithFormat:@"%i", levelCount];
    [self updateScore];
}
