How to add different images for different cell to a tableView programmatically (Swift)

Question

I want to add different images to different cell in a tableView where i have already a list of string, this is my code, the struct of category:

  struct QCategoryy {
        var name:String
        var image:UIImage
        var isSelected = false
        init(name:String, image.UIImage) {
            self.name = name
            self.image = image
}


    extension QCategoryy: ExpressibleByStringLiteral {
        init(stringLiteral value: String) {
            self.name = value
        }
        init(unicodeScalarLiteral value: String) {
            self.init(name: value)
        }
        init(extendedGraphemeClusterLiteral value: String) {
            self.init(name: value)
        }
    }

and here is where i create the list (which i will then add to the tableView)

import Foundation
import UIKit
import CoreLocation
import Alamofire

class NearbyPlaces {
    static func getCategories() -> [QCategoryy] {
        let list:[QCategoryy] = ["Art_gallery", "Amusement_park", "Zoo", "Bar", "Night_club", "Movie_theater", "Restaurant", "Shopping_mall", "Atm", "Gym", "Store", "Spa", "Museum", "Stadium", "Hardware_store", "Casino", "Library", "Painter", "Book_store", "Bowling_alley", "Cafe", "Clothing_store",  ]
        return list
    }

for each item in the list i want to add a specific image of the cell size but how can i do?

EDIT

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
        let identifier = "CATEGORY_CELL"
        let cell = tableView.dequeueReusableCell(withIdentifier: identifier, for: indexPath)
        let selectedIndexPaths = tableView.indexPathsForSelectedRows
        let rowIsSelected = selectedIndexPaths != nil && selectedIndexPaths!.contains(indexPath)
       /* cell.accessoryType = rowIsSelected ? .checkmark : .none  */
        cell.accessoryType = list[indexPath.row].isSelected ? .checkmark : .none
        cell.textLabel?.text = list[indexPath.row].name
        return cell
    }

Answer 1

The List ist static, right?

Why do you not add an image url (or what u need) to your object. That would solve your problem ^^. So you can call it in cell for row :)

Answer 2

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
 let cell = tableView.dequeueReusableCell(withIdentifier: "your_cell_identifier") 
let category = NearbyPlaces.getCategory()[indexPath.row] 
cell.image = category.image 
cell.name = category.name
return cell!

}

You cant read it in the comments^^

Answer 3

As @TMX said, you can use:

func cellForRow(at indexPath: IndexPath) -> UITableViewCell?

See: https://developer.apple.com/documentation/uikit/uitableview/1614983-cellforrow

And: https://stackoverflow.com/a/8079765/7510062

And if you just started to code, you should follow this tutorial: https://developer.apple.com/library/content/referencelibrary/GettingStarted/DevelopiOSAppsSwift/CreateATableView.html

..in order to understand how it works, then it should be EASY!

It would be better if you can create custom cells. rather with your same code you just below line in CellForRowAtIndex method.

    func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
            let identifier = "CATEGORY_CELL"
            let cell = tableView.dequeueReusableCell(withIdentifier: identifier, for: indexPath)
            let selectedIndexPaths = tableView.indexPathsForSelectedRows
            let rowIsSelected = selectedIndexPaths != nil && selectedIndexPaths!.contains(indexPath)

            cell.accessoryType = list[indexPath.row].isSelected ? .checkmark : .none
            cell.textLabel?.text = list[indexPath.row].name
            cell.imageView?.image = list[indexPath.row].image // make sure you are saving images in struct.
            return cell
        }

initalize as

init(name:String, image:UIImage) {
            self.name = name
            self.image = image
        }

change func as

static func getCategories() -> [QCategoryy] {
        let list:[QCategoryy] = [QCategoryy(name: "name", image: UIImage(named: "imageName")!)]
        return list
    }

extension code:

extension QCategoryy: ExpressibleByStringLiteral {
     init(stringLiteral value: String) {
            self.name = value
            self.image = UIImage()
        }
        init(unicodeScalarLiteral value: String) {
            self.init(name: value, image: UIImage())
        }
        init(extendedGraphemeClusterLiteral value: String) {
            self.init(name: value, image: UIImage())
        }
    }
