arrays - 如何连接两个不同的数组并同时随机化它们？

Question

我正在尝试连接 2 个数组，但同时对它们进行随机化，例如:

数组 1:A、B、C、D、E数组2:1,2,3,4,5

当我按下显示按钮时，我希望字母与数字相对应，但我希望它们是随机的

C/3、A/1、E/5

现在我的源代码随机化了我的数组，但它们没有按顺序排列，这意味着我得到了 A/2、E/1、C、5。这是我的代码:

 @IBOutlet weak var randomLetter: UIButton!
 @IBOutlet weak var randomNumber: UIButton!

 @IBAction func showLetters(_ sender: Any) {

    let array1 = ["A","B","C","D","E"]


    let array2 = ["1","2","3","4","5"]


      let randomLetterGen = Int (arc4random_uniform(UInt32(array2.count)))
    randomLetter.text = array2 [randomLetterGen]

      let randomNumberGen = Int (arc4random_uniform(UInt32(array1.count)))
    randomNumber.text = array1 [randomNumberGen]

}

Answer 1

您可以通过对 array1 和 array2 使用相同的随机索引来实现这一点。

考虑下面的代码:

let array1 = ["A","B","C","D","E"]
let array2 = ["1","2","3","4","5"]

let randomLetterGen = Int(arc4random_uniform(UInt32(array2.count)))
randomLetter.text = array2[randomLetterGen] //C
randomNumber.text = array1[randomLetterGen] //3
