如何设置新值以更改我的Story应用程序的问题

问题描述

我想根据用户选择更改故事。但是，每次我运行该应用程序时，它总是显示相同的问题。具体来说，是第30行和第41行。我不想在那儿写0，但IDK怎么办。我确实拥有不混淆的“结构”。

var hikayeler = [
Story(
    title: "Your car has blown a tire on a winding road in the middle of Nowhere with no cell phone reception. You decide to hitchhike. A rusty pickup truck rumbles to a stop next to you. A man with a wide brimmed hat with soulless eyes opens the passenger door for you and asks: 'Need a ride,boy?'.",choice1: "I'll hop in. Thanks for the help!",choice1Destination: 2,choice2: "Better ask him if he's a murderer first.",choice2Destination: 1
),Story(
    title: "He nods slowly,unfazed by the question.",choice1: "At least he's honest. I'll climb in.",choice2: "Wait,I kNow how to change a tire.",choice2Destination: 3
),

解决方法

一种选择是在决定选择哪个故事时使用随机数：

let index = Int.random(0..<hikayeler.count)

另一种选择是记录用户看到过哪些故事，以确保他们在启动时总是得到不同的故事。

由您决定要如何运行您的应用。

编辑-为了使故事继续进行，您需要一个存储当前索引的变量。

class ViewController: UIViewController {
    var index = 0

    @IBAction func button1(_ sender: UIButton) {
        let variable1 = hikayeler[index]
        ...
        index = variable1
    }
}
