ios - Xcode UI按钮函数

Question

我目前正在尝试创建答题器/金钱游戏，需要一些帮助。所以基本上，该应用程序由一个按钮组成，每次单击它时都会提供 +1 个硬币。例如，如果您购买“10 个硬币的双倍硬币”，我想将金额从 +1 更改为 +2。

Click here to see how the app looks right now, it might be easier to understand.

下面是一些可能相关的编码。

    @IBAction func button(_ sender: UIButton) {
    score += 1
    label.text = "Coins: \(score)"
    errorLabel.text = ""
    func doublee(sender:UIButton) {
        score += 2
    }


   @IBAction func points(_ sender: UIButton) {

    if score >= 10 {
    score -= 10
    label.text = "Coins: \(score)"
    doublePoints.isEnabled = false
    xLabel.text = "2X"
    xLabel.textColor = UIColor.blue
    } else {
        errorLabel.text = "ERROR, NOT ENOUGH MONEY"
    }

请记住，我刚刚开始编程，希望收到所有反馈。谢谢!

添加一个变量来跟踪您点击按钮时获得的分数，并且当您购买分数乘数时，相应地增加变量，如下所示:

var scoreIncrease = 1 // this is how much the score increases when you tap

// This is called when the "CLICK HERE" button is tapped
@IBAction func button(_ sender: UIButton) {
    score += scoreIncrease
    label.text = "Coins: \(score)"
    errorLabel.text = ""
}

// This is called when you buy the 2x
@IBAction func points(_ sender: UIButton) {

  if score >= 10 {
     score -= 10
     label.text = "Coins: \(score)"
     doublePoints.isEnabled = false
     xLabel.text = "2X"
     xLabel.textColor = UIColor.blue
     scoreIncrease *= 2 // increase by x2
  } else {
     errorLabel.text = "ERROR, NOT ENOUGH MONEY"
  }
}
