arrays - 使用索引从另一个数组更改数组字符串值

Question

我想在打乱另一个数组后更改数组中的字符串值，我该怎么做？

示例:

var array1 = [1,2,3,4,5,6]

var stringarray = ["\\(array1[0]) = 1") 

array1.shuffle()

print(stringarray)

如何将原始字符串数组值更改为新的随机值？

谢谢

任务:

    @IBAction func nextQuestion(_ sender: Any) {

    if levelSelected == 1 {
        questionLabel.text = standardRules.randomElement()
    }
    players.shuffle()
    print(players)

standardRules 有一个字符串值，取值为 players[0]

基本上我想做的是:

我正试图在这样的字符串中获取 2 个不同的随机值

    var players = ["Jack, John, Michael, Peter"]
    var playersArray = ["\(players.randomElement) and \(players.randomElement) has to battle")

我该怎么做，让它获取 2 个不同的值？

你可以通过这段代码让它变得非常简单:

var players = ["Jack", "John", "Michael", "Peter"]

// get the first random element
var random1 = players.randomElement()

//delete that element so you can't duplicate it 
players = players.filter{$0 != random1}

//get your second radom element
var random2 = players.randomElement()

//add your element again
players.append(random1!)
