ios - 如何自动生成基于类的对象 iOS Swift

Question

抱歉，我无法让代码片段正常工作。不知道如何让它识别 Swift。

我的问题是我有一个名为“Crewman”的类，我想在“generateCrew”函数中基于这个类生成 25 个对象。 (我目前正在 Xcode 中的测试文件中尝试这个)我不知道如何修复它以便它们都以不同的方式命名。如果我给这些对象一个特定的名称，那么在接下来的 24 次我运行该函数时它只会覆盖第一个。

我是 iOS/Swift 的新手，所以很想得到帮助……尤其是对我来说尽可能地愚蠢哈哈哈哈谢谢! :D

//This is the class constructor, if thats the right word...

class Crewman {
    var name: String!
    var navSkill: Int!      // #/10
    var combatSkill: Int!   // #/10
    var morale: Int!        // #/10
    var loyalty: Int!       // #/10
}


//This is where I am trying to create the objects within a function 

    var crewNames =
    ["Chance", "Bruno", "Toby", "Damien", "Rafael", "Domenic", "Weston", "Edison", "Chris", "Grant", "Cortez", "Darren", "Nicolas", "Everette", "Jason", "Vicente", "Noe", "Ricky", "Ivory", "Thomas", "Guillermo", "Isreal", "Ben", "Winfred", "Lincoln", "Kareem", "Antwan", "Greg", "Lawrence", "Corey", "Todd", "Jeffery", "Rayford", "Julio", "Manual", "Chi", "Bradford", "Devon", "Bryan", "Andreas", "Don", "Erik", "Bobbie", "Tyree", "Felipe", "Clifton", "Carrol", "Kasey", "Cliff", "Jack"]

    //Lincoln is no.25

    var crewmenAll = [Crewman]()

    func generateCrew()
    {
        for i in 1...25
        {
            var crewNames[i]:Crewman!
            crewmenAll.append(nameOfCrew)
            print(crewmenAll)
        }
    }

    override func setUp() {

        for i in 1...25
        {
            let x = Int.random(in: 0..<50)
            let name = crewNames[x]

            let navInt = Int.random(in: 3...7)
            let combatInt = Int.random(in: 3...7)
            let moraleInt = Int.random(in: 3...7)


            crewmenAll[i] = Crewman(name: name, navSkill: navInt, combatSkill: combatInt, morale: moraleInt, loyalty: 5)

        }

首先你应该改变你的类，因为没有必要像你那样强制解包(!)普通属性，而是添加一个合适的初始化方法

class Crewman {
    var name: String
    var navSkill: Int      
    var combatSkill: Int
    var morale: Int     
    var loyalty: Int    

    init(name: String, navSkill: Int, combatSkill: Int, morale: Int, loyalty: Int) {
        self.name = name

        self.navSkill = navSkill
        self.combatSkill = combatSkill
        self.morale = morale
        self.loyalty = loyalty
    }
}

我不明白为什么你有这两个功能 generateCrew和 setUp因为它们看起来很相似所以我只保留 setUp .

在setUp我保留了大部分代码并使用了新的 init 方法，然后添加了每个新的 Crewman。使用 append 反对数组购买的末尾.

为了获得随机名称，我打乱了名称数组，使它们以随机顺序排列，然后我可以使用索引 i 从该数组中挑选它们。 .还要注意数组的索引从 0 而不是 1 开始，所以我更改了 for循环一下

var crewmenAll = [Crewman]()
var crewmen = [String: Crewman]()

func setUp() {
    let randomOrder = crewNames.shuffled()

    for i in 0..<25 {
        let name = randomOrder[i]

        let navInt = Int.random(in: 3...7)
        let combatInt = Int.random(in: 3...7)
        let moraleInt = Int.random(in: 3...7)

        crewmenAll.append(Crewman(name: name, navSkill: navInt, combatSkill: combatInt, morale: moraleInt, loyalty: 5))
    }
    crewmen = crewmenAll.reduce(into: [:]) {$0[$1.name] = $1 }
}
