ios - 获取用于编辑的 uiSegmentControl 值

Question

我有一个分段控件来定义准备食谱的难度级别。我需要在一个我不会对其进行编辑的配方中加载赋值。遵循代码:

@IBOutlet var segNewDifficultyLevel: UISegmentedControl!

@IBOutlet var ingredientTableView: UITableView!
@IBOutlet var directionTableView: UITableView!

weak var delegate: AddNewRecipeViewControllerDelegate?

// MARK: - Variabili Globali
var editRecipe: RecipeModel!

var difficultyLevel: String!

var ingredients: [IngredientModel] = []
var directions: [DirectionModel] = []

此代码在 viewDidLoad 中:

if let editToRecipe = editRecipe {
            title = "Edit Recipe"
            // Load data from Recipe Detail into editRecipe 
            viewImageNewRecipe.image = editToRecipe.imageRecipe
            fieldNewRecipeName.text = editToRecipe.nameRecipe
            fieldNewQuantityFor.text = editToRecipe.quantityRecipe
            fieldNewPrepareTime.text = editToRecipe.preparationTime
            fieldNewCookingTime.text = editToRecipe.cookingTime
            fieldNewBakingTemp.text = editToRecipe.bakingTempRecipe

            /* Load the Difficulty Level selected in the recipe */
            segNewDifficultyLevel.selectedSegmentIndex = ???

有人可以帮帮我吗？非常感谢!!!

配方模型类:

class RecipeModel: NSObject, NSCoding
{
    var nameRecipe: String
    var quantityRecipe: String
    var recipeTime: String
    var preparationTime: String
    var cookingTime: String
    var bakingTempRecipe: String

    var difficultyLevelRecipe: String

    var imageRecipe: UIImage

    var ingredients: [IngredientModel]
    var directions: [DirectionModel]

    var recipeTimeInt: Int
    {
        var sumRecipeTime: Int = Int(recipeTime)!
        sumRecipeTime = Int(preparationTime)! + Int(cookingTime)!
        return sumRecipeTime
    }

    init(nameRecipe: String, quantityRecipe: String, recipeTime: String, preparationTime: String, cookingTime: String, bakingTempRecipe: String, difficultyLevelRecipe: String, imageRecipe: UIImage, ingredients: [IngredientModel], directions: [DirectionModel]) {
        self.nameRecipe = nameRecipe
        self.quantityRecipe = quantityRecipe
        self.recipeTime = recipeTime
        self.preparationTime = preparationTime
        self.cookingTime = cookingTime
        self.bakingTempRecipe = bakingTempRecipe
        self.difficultyLevelRecipe = difficultyLevelRecipe
        self.imageRecipe = imageRecipe
        self.ingredients = ingredients
        self.directions = directions
    }

如果您在 difficultyLevelRecipe 中将索引作为字符串获取，那么您可以将其转换为 Int 为 selectedSegmentIndex 设置的值，如下所示:

segNewDifficultyLevel.selectedSegmentIndex = Int(editToRecipe.difficultyLevelRecipe)

但是，如果您得到一些其他值，例如 difficultyLevelRecipe 的值/名称，那么您需要根据 segNewDifficultyLevel 中可用的值/名称来设置它。您需要根据条件通过比较段名称和您的 difficultyLevelRecipe 来管理它。

希望你思路清晰，明白该怎么做。
