I have a func which that is putting two lists together into a dictionary. I want this dictionary to print each [String : String] into a new cell on my table view. I'm only getting one cell back, which I know why (returning one item). However I can not figure out how to access my dictionary list to return each item in the dictionary. Here is a picture of what I'm currently getting. Screenshot of current results

Here is my struct and funcs to get the items and put into a dictionary.

//struct for the dictionary that holds all meals
struct RootData: Codable {
    var meals: [MealDetails]
}

//struct for dessert details of each meal
struct MealDetails: Codable {
    var id: String
    var name: String
    var instructions: String?
    var image: String?

    var strIngredient1: String?
    var strIngredient2: String?
    var strIngredient3: String?
    var strIngredient4: String?
    var strIngredient5: String?
    var strIngredient6: String?

    }
    
    func getAllIngredients() -> [String] {

        return measures
        
    }
    
    func getIngredientsAndMeasures() -> [String : String] {
        var dictionary: [String : String] = [:]
        let measures = getAllMeasures()
        for (index, element) in getAllIngredients().enumerated() {
            if !element.isEmpty {
                dictionary[element] = measures[index]
            }
        }
        return dictionary
    }
    
}

Here is my view controller:

class DetailTableViewController: UIViewController, UITableViewDelegate, UITableViewDataSource {

    var idMeal: String = ""
    var mealDetails = [MealDetails]()

    
    //UI Oulets (Image, Dessert Name, Instructions, Ingredents)
    @IBOutlet weak var nameLabel: UILabel!
    @IBOutlet weak var imageView: UIImageView!
    @IBOutlet weak var instructionsText: UITextView!
    @IBOutlet weak var detailTableView: UITableView!
    
    override func viewDidLoad() {
        super.viewDidLoad()
        
        
        getApiDetailData {
            print("data loaded")
            self.view.reloadInputViews()
            self.detailTableView.reloadData()
            
            
            self.nameLabel.text = self.mealDetails[0].name
            self.instructionsText.text = self.mealDetails[0].instructions

            let urlString = (self.mealDetails[0].image)
            let url = URL(string: urlString!)
            self.imageView.downloaded(from: url!)

        }
        detailTableView.delegate = self
        detailTableView.dataSource = self
        
    }

    func tableView(_ detailTableView: UITableView, numberOfRowsInSection section: Int) -> Int {
        return mealDetails.count
    }
    func tableView(_ detailTableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
        let cell = UITableViewCell(style: .default, reuseIdentifier: nil)
        cell.textLabel?.text = "\(mealDetails[indexPath.row].getIngredientsAndMeasures())"
        return cell
    }

I've tried a number of things in the numbersOfRowsInSection function to access my dictionary. Any help would be much appreciated. I feel very close but not sure what I'm overlooking.

CodePudding user response：

I think you should use a custom type for each ingredient and measurement

struct Ingredient {
    let name: String
    let measurement: String
}

and then you add a function to create an array of them from a MealDetails object by adding this method to the struct

func createIngredients() -> [Ingredient] {
    return zip(getAllMeasures(), getAllIngredients()).map {
        if $0.0.isEmpty { return nil }
        return Ingredient(name: $0.0, measurement: $0.1)
    }
}

Then you can have a property for this array in your view controller

var ingredients = [Ingredient]()

and assign to it in the closure in viewDidLoad

self.ingredients = self.mealDetails[0].createIngredients()

and then use it as the data source for your table view

func tableView(_ detailTableView: UITableView, numberOfRowsInSection section: Int) -> Int {
    return ingredients.count
}
func tableView(_ detailTableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
    let cell = UITableViewCell(style: .default, reuseIdentifier: nil)
    cell.textLabel?.text = "\(ingredients[indexPath.row].name)" // or whatever you want here
    return cell
}
