ios - 如何通过我的表格 View 单元格的更新 View 函数传递一个字符串数组？

Question

我有一个 swift 文件目前用作单例，最终会 是我用来获取所有 API 数据的位置，我有一个用于我的 iboulet 的 View 文件和一个用于更新 tableview 单元格 View 的函数，以及一个包含我的变量和初始化程序的模型文件。一切正常，直到我尝试传递一个数组而不是一个字符串，你能帮我通过我的更新 View 函数传递一个或多个数组吗？ Current error

Singleton

class DataServices{
    static let instance = DataServices()



    private let ackee = [

        RecipeInfo(image: "15", title: "Ackee & Saltfish", time: "30 mins", complication: "Easy", serving: "5 people", ingredients: ["Canned Ackee", "Black Pepper", "Salt Fish"], instructions: "again")
    ]



    func getRecipe() -> [RecipeInfo]{
        return ackee
    }

Update View function for the cell

class RecipeCell: UITableViewCell {


    @IBOutlet weak var recipeImage: UIImageView!
    @IBOutlet weak var recipeTitle: UILabel!
    @IBOutlet weak var recipeTime: UILabel!
    @IBOutlet weak var recipeStatus: UILabel!
    @IBOutlet weak var mealCount: UILabel!
    @IBOutlet weak var ingredients: UILabel!
    @IBOutlet weak var instructions: UILabel!




    func updateViews(recipe: RecipeInfo){
        recipeImage.image = UIImage(named: recipe.image)
        recipeTitle.text = recipe.title
        recipeTime.text = recipe.time
        recipeStatus.text = recipe.complication
        mealCount.text = recipe.serving
        ingredients.text = recipe.ingredients
        instructions.text = recipe.instructions

    }

Model with variables and initializer

struct RecipeInfo {


    private(set) public var image: String
    private(set) public var title: String
    private(set) public var time: String
    private(set) public var complication: String
    private(set) public var serving: String
    private(set) public var ingredients: String
    private(set) public var instructions: String



    init(image: String, title: String, time: String, complication: String, serving: String, ingredients: String, instructions: String) {
        self.image = image
        self.title = title
        self.time = time
        self.complication = complication
        self.serving = serving
        self.ingredients = ingredients
        self.instructions = instructions
    }

错误很明显:ingredients 被声明为 String 但在 Singleton 中传递了一个数组 ([String])。这个名字暗示了一个数组。

private(set) 变量可能看起来很酷，但它们是无稽之谈。这不是 Objective-C。如果你想要常量，将它们声明为常量 (let)

这就足够了，您可以免费获得初始化程序:

struct RecipeInfo {       
    let image: String
    let title: String
    let time: String
    let complication: String
    let serving: String
    let ingredients: [String]
    let instructions: String
}

加入数组在 TableView 中显示成分

ingredients.text = recipe.ingredients.joined(separator: ", ")
