Question

我是编程新手。我想在iOS上制作一个简单的游戏。我有一个带有名单列表的数组，我有两个按钮，可以从数组中随机选择项目。

我的问题是，在选择ARRAY ITEM后，我需要添加哪些代码才能删除ARRAY ITEM。

var playerName = ["James", "John", "Paul", "Chris", "BoB", "Sam", "Mike", "Jason"]


//IBOutlets
@IBOutlet weak var player1BTN: UIButton!
@IBOutlet weak var player2BTN: UIButton!


//IBActions
@IBAction func player1BTNpressed(_ sender: Any) {
    print("player 1")

    //Randomize player from 0 to 26
    let player1 = Int(arc4random_uniform(26))

    // Change Button Title Text
    player1BTN.setTitle((playerName[player1]), for: UIControlState.normal)

}

@IBAction func player2BTNpressed(_ sender: Any) {
    print ("player 2")

    //Randomize player from 0 to 26
    let player2 = Int(arc4random_uniform(26))

    // Change Button Title Text
    player2BTN.setTitle((playerName[player2]), for: UIControlState.normal)

}

希望这是有道理的。谢谢你的帮助。

     Please try this code, it might be helped you:-

        var playerName = ["James", "John", "Paul", "Chris", "BoB", "Sam", "Mike", "Jason"]

                let item = "Chris"

                if let index = playerName.index(of: item) {
                    playerName.remove(at: index)
                    print(playerName)
                }

Output like this:- ["James", "John", "Paul", "BoB", "Sam", "Mike", "Jason"]

不要在Swift中重复数组项
