I am very new to Swift (less than one week) I create a table view where I have more cells , each cell gets create from a .xib file, and the fields get populated because I create an array of objects that are used in order to populate the cells.
I have a file called: MenuWeekViewControoler.swift where I have the tableView.
I have a file called FoodTableViewCell.swift which is connected with the .xib file
Inside the FoodTableViewCell I have the uipickerview and in the MenuWeekViewControoler I visualise the pickerview and interact with it.
My wish is to get the value of the picker view for each separate cell and I don't really know how to do it.
I will attach the code of the 3 files in order for the code to make sense:
MenuWeekViewControoler :
import UIKit
class MenuWeekViewController : UIViewController, UITableViewDelegate, UITableViewDataSource {
var menus : [Menu] = [
Menu(nameMenu: "BBQ", priceMenu: 8, pickerDada: ["0","1","2","3","4","5","6","7","8","9","10"]),
Menu(nameMenu: "BBQ2", priceMenu: 8, pickerDada: ["0","1","2","3","4","5","6","7","8","9","10"]),
Menu(nameMenu: "BBQ3", priceMenu: 8, pickerDada: ["0","1","2","3","4","5","6","7","8","9","10"]),
Menu(nameMenu: "BBQ4", priceMenu: 8, pickerDada: ["0","1","2","3","4","5","6","7","8","9","10"]),
Menu(nameMenu: "BBQ4", priceMenu: 8, pickerDada: ["0","1","2","3","4","5","6","7","8","9","10"]),
Menu(nameMenu: "BBQ4", priceMenu: 8, pickerDada: ["0","1","2","3","4","5","6","7","8","9","10"]),
]
var test = FoodTableViewCell()
@IBOutlet weak var tableView: UITableView!
@IBOutlet weak var nameSection: UITextField!
@IBOutlet weak var privateGuestsUIPicker: UIPickerView!
@IBOutlet weak var BusinessGuestUIPicker: UIPickerView!
@IBOutlet weak var commentSection: UITextField!
override func viewDidLoad() {
super.viewDidLoad()
tableView.dataSource = self
tableView.delegate = self
tableView.rowHeight = 100
tableView.register(UINib(nibName: "FoodTableViewCell", bundle: nil), forCellReuseIdentifier: "ReusableMenuCell")
}
@IBAction func updateOrders(_ sender: UIButton) {
}
@IBAction func sendOrder(_ sender: UIButton) {
}
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return menus.count
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "ReusableMenuCell", for: indexPath) as! FoodTableViewCell
cell.menuName?.text = menus[indexPath.row].nameMenu
cell.priceMenu?.text = String("\(menus[indexPath.row].priceMenu) CHF")
return cell
}
func tableView(_ tableView: UITableView, didDeselectRowAt indexPath: IndexPath) {
print(menus[indexPath.row].nameMenu)
}
}
FoodTableViewCell :
import UIKit
class FoodTableViewCell: UITableViewCell,UIPickerViewDelegate, UIPickerViewDataSource {
var pickerDada = ["0","1","2","3","4","5","6","7","8","9","10"]
@IBOutlet weak var quantityMenu: UIPickerView!
@IBOutlet weak var priceMenu: UILabel!
@IBOutlet weak var menuName: UILabel!
override func awakeFromNib() {
super.awakeFromNib()
quantityMenu.dataSource = self
quantityMenu.delegate = self
quantityMenu.setValue(UIColor.white, forKey: "textColor")
// Initialization code
}
override func setSelected(_ selected: Bool, animated: Bool) {
super.setSelected(selected, animated: animated)
// Configure the view for the selected state
}
func numberOfComponents(in pickerView: UIPickerView) -> Int {
return 1
}
func pickerView(_ pickerView: UIPickerView, numberOfRowsInComponent component: Int) -> Int {
return 11
}
internal func pickerView(_ pickerView: UIPickerView, titleForRow row: Int, forComponent component: Int) -> String? {
return pickerDada[row]
}
func pickerView(_ pickerView: UIPickerView, didSelectRow row: Int, inComponent component: Int)
{
print(pickerDada[row])
}
}
Menu struct :
import UIKit
struct Menu{
var nameMenu : String
var priceMenu : Int
var pickerDada : [String] = [String]()
}
Thank you to everyone willing to help
in FoodTableViewCell you should define a delegate protocol and define it as a variable such as:
import UIKit
protocol FoodCellDelegate: AnyObject {
func tapFood(food: YourFoodModel) or // func tapFood(food: pickerDada) or whatever you want pass it
}
class FoodTableViewCell: UITableViewCell,UIPickerViewDelegate, UIPickerViewDataSource {
//define a variable type of delegate
weak var delegate: FoodCellDelegate?
.
.
.
func pickerView(_ pickerView: UIPickerView, didSelectRow row: Int, inComponent component: Int)
{
print(pickerDada[row])
// add this
delegate?.tapFood(food: pickerData[row])
}
}
after that you must delegate it to your MenuWeekViewController:
class MenuWeekViewController : UIViewController, UITableViewDelegate, UITableViewDataSource {
.
.
.
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "ReusableMenuCell", for: indexPath) as! FoodTableViewCell
cell.menuName?.text = menus[indexPath.row].nameMenu
cell.priceMenu?.text = String("\(menus[indexPath.row].priceMenu) CHF")
// add this
cell.delegate = self
return cell
}
.
.
.
}
extension MenuWeekViewController: FoodCellDelegate {
func tapFood(food: YourFoodModel) {
print it
}
}
