Using multiple UIPickerViews in dynamic UITableView - ios

Question

I am trying to make use of UIPickerViews, whereby the user can select an "amount"(number) between 1 and 20. In my TableviewCell there is a label and the picker.
Before I implemented the PickerViewDelegate and PickerViewDatasource, everything was fine. Since then I cannot even check if my code is right, cause it gives me "Fatal error: Unexpectly found nil..." for the label which has the array soloJobs (Array is not empty). So I guess I am making something fundamentally wrong.
At the end my achievment would be to store the values of the jobAmountPickerin the selAmountArray for given index.
Maybe someone can help.
This is my tableviewcell:
import UIKit
var globalAmount:[String] = []
class ProjectCharacterTableViewCell: UITableViewCell, UIPickerViewDelegate, UIPickerViewDataSource {
var jobAmount: [String] = []
var pickerData = ["1", "2", "3", "4","5","6","7","8","9","10","11","12","13","14","15","16","17","18","19","20"]
var selAmountArray: [String] = []
static let identifier = "ProjectCharacterTableViewCell"
#IBOutlet weak var jobLabel: UILabel!
#IBOutlet weak var jobAmountPicker: UIPickerView!
override func awakeFromNib() {
self.pickerData = Array<String>()
self.jobAmountPicker.delegate = self;
self.jobAmountPicker.delegate = self;
super.awakeFromNib()
}
override func setSelected(_ selected: Bool, animated: Bool) {
super.setSelected(selected, animated: animated)
// Configure the view for the selected state
}
func pickerView(_ pickerView: UIPickerView, numberOfRowsInComponent component: Int) -> Int {
return pickerData.count
}
func numberOfComponents(in pickerView: UIPickerView) -> Int {
return 1
}
func pickerView(_ pickerView: UIPickerView, didSelectRow row: Int, inComponent component: Int) {
let selectedAmount = pickerData[row] as String
selAmountArray.append(selectedAmount)
globalAmount = selAmountArray
}
func pickerView(pickerView: UIPickerView, titleForRow row: Int, forComponent component: Int) -> String? {
return pickerData[row]
}
}
And that's my viewController:
import UIKit
import FirebaseDatabase
import Foundation
import FirebaseFirestoreSwift
import CodableFirebase
class ProjectCharacterViewController: UIViewController, UITextFieldDelegate {
// MARK: - Properties
#IBOutlet weak var specTxt: UITextField!
#IBOutlet weak var difficultyTxt: UITextField!
#IBOutlet weak var budgetTxt: UITextField!
#IBOutlet weak var tableView: UITableView!
var soloJobs: [String] = []
var jobAmount: [String] = []
var rowBeingEditet : Int? = nil
var indexesNeedPicker: [NSIndexPath]?
var i: Int?
override func viewWillAppear(_ animated: Bool) {
super.viewWillAppear(animated)
getJobs(for: User.current) { (memberJob) in
}
}
override func viewDidLoad() {
tableView.register(ProjectCharacterTableViewCell.self, forCellReuseIdentifier: "ProjectCharacterTableViewCell")
super.viewDidLoad()
}
// MARK: - Functions
func getJobs(for user: User, completion: #escaping ([MemberJobsStruct]) -> Void) {
var jobs: [String] = []
let ref = Database.database().reference().child("team").child(user.uid)
ref.observe(DataEventType.value, with: { snapshot in
for case let child as DataSnapshot in snapshot.children {
guard let value = child.value as? [String: Any] else {
return completion ([])
}
let memberJob = value["memberJob"] as! String
jobs.append(memberJob)
self.soloJobs = self.removeDuplicates(array: jobs)
DispatchQueue.main.async {
self.tableView.reloadData()
}
}
})
}
func removeDuplicates(array: [String]) -> [String] {
var encountered = Set<String>()
var result: [String] = []
for value in array {
if encountered.contains(value) {
// Do not add a duplicate element.
}
else {
// Add value to the set.
encountered.insert(value)
// ... Append the value.
result.append(value)
}
}
return result
}
#IBAction func show(_ sender: Any) {
print("SoloJobs: ", soloJobs)
print("Thats the job amount: ", jobAmount)
print("Global amount :", globalAmount)
}
}
// MARK: - UITableViewDataSource
extension ProjectCharacterViewController: UITableViewDataSource {
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return soloJobs.count
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "ProjectCharacterTableViewCell") as! ProjectCharacterTableViewCell
cell.jobLabel.text = soloJobs[indexPath.row]
i = indexPath.row
cell.jobAmountPicker.reloadAllComponents();
return cell
}
}
// MARK: - UITableViewDelegate
extension ProjectCharacterViewController: UITableViewDelegate {
func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
return 60
}
}
