Swift中两行重复代码是否首选单独的函数？

Question

我正在设计一个小型游戏，并且已经确定了一种初始方法，该方法是根据询问问题和按下输入按钮之间经过的秒数来分配分数。

我知道最佳实践是创建一个要在要重复的行时调用的函数，但是在我看来，当只有两行重复四次时调用它可能有点多余。使用下面的代码，为每个部分的最后两行创建一个函数对我来说是“适当”还是更优选？

//Assigns points to score based on elapsed time and updates score
func updateScore() {

    timer.invalidate()

    if timeToAnswer < 3 {
        questionScore = 10  //10 points for answering so quickly
        score = score + questionScore  //Updates score
        timeToAnswer = 0  //Resets var timeToAnswer
    }

    else if (timeToAnswer >= 3) && (timeToAnswer < 6) {
        questionScore = 7
        score = score + questionScore
        timeToAnswer = 0
    }

    else if (timeToAnswer >= 6) && (timeToAnswer < 11) {
        questionScore = 10 - timeToAnswer
        score = score + questionScore
        timeToAnswer = 0
    }

    else {
        questionScore = 1
        score = score + questionScore
        timeToAnswer = 0
    }
}

非常感谢任何提供帮助或建议的人。

您可以采用更好的方式进行操作。 您也可以使用switch语句。无论如何：

func updateScore() {

    timer.invalidate()

    if timeToAnswer < 3 {
        questionScore = 10
    }

    else if (timeToAnswer >= 3) && (timeToAnswer < 6) {
        questionScore = 7
    }

    else if (timeToAnswer >= 6) && (timeToAnswer < 11) {
        questionScore = 10 - timeToAnswer
    }

    else {
        questionScore = 1
    }

    score = score + questionScore  //Updates score
    timeToAnswer = 0  //Resets var timeToAnswer
}
