DatePicker passing data - ios

Question

I have a successful date picker and on the following page a stepper/number picker that allows users to select dates, and item quantities. In a new view, I would like to display all the previous information for them to review. I have a few methods in place but they don't seem to work. I am guessing it is because they aren't textFields, and some extra code is needed in order to ask the UIdatepicker and Stepper to pass the information. Take a look below please :)
Here is my date picker View Controller
import UIKit
class StoreDatesViewController: UIViewController {
#IBOutlet weak var nextButton: UIButton!
#IBOutlet weak var dropOff: UITextField!
#IBOutlet weak var pickUp: UITextField!
let datePicker = UIDatePicker()
override func viewDidLoad() {
super.viewDidLoad()
showDatePicker()
}
override func viewWillAppear(_ animated: Bool) {
nextButton.isEnabled = true
}
func showDatePicker(){
//Format Date
datePicker.datePickerMode = .date
datePicker.preferredDatePickerStyle = .inline
datePicker.backgroundColor = UIColor(named: "yellow-2")
//ToolBar
let toolbar = UIToolbar();
toolbar.sizeToFit()
let toolbar2 = UIToolbar();
toolbar2.sizeToFit()
let doneButton = UIBarButtonItem(title: "Done", style: .plain, target: self, action: #selector(donedatePicker));
let cancelButton = UIBarButtonItem(title: "Cancel", style: .plain, target: self, action: #selector(cancelDatePicker));
let doneButton2 = UIBarButtonItem(title: "Done", style: .plain, target: self, action: #selector(donedatePicker2));
let cancelButton2 = UIBarButtonItem(title: "Cancel", style: .plain, target: self, action: #selector(cancelDatePicker2));
toolbar.setItems([doneButton,cancelButton], animated: false)
toolbar.tintColor = .white
toolbar.backgroundColor = .red
toolbar2.setItems([doneButton2,cancelButton2], animated: false)
toolbar2.tintColor = .white
dropOff.inputAccessoryView = toolbar
dropOff.inputView = datePicker
pickUp.inputAccessoryView = toolbar2
pickUp.inputView = datePicker
}
#objc func donedatePicker(){
let formatter = DateFormatter()
formatter.dateFormat = "dd/MM/yyyy"
dropOff.text = formatter.string(from: datePicker.date)
self.view.endEditing(true)
}
#objc func donedatePicker2(){
let formatter = DateFormatter()
formatter.dateFormat = "dd/MM/yyyy"
pickUp.text = formatter.string(from: datePicker.date)
self.view.endEditing(true)
}
#objc func cancelDatePicker(){
self.view.endEditing(true)
}
#objc func cancelDatePicker2(){
self.view.endEditing(true)
}
#IBAction func didTapNext() {
let dropOff = dropOff.text
let pickUp = pickUp.text
let storeDetailsVC = self.storyboard?.instantiateViewController(withIdentifier: "storeDetailsVC") as! storeDetailsViewController
storeDetailsVC.dropOff = dropOff!
storeDetailsVC.pickUp = pickUp!
}
}
Here is my number Pick View Controller
import UIKit
class StoreQuantityViewController: UIViewController{
#IBOutlet weak var numbers: UILabel!
override func viewDidLoad() {
super.viewDidLoad()
}
#IBAction func stepper(_ sender: UIStepper) {
numbers.text = String(Int(sender.value))
}
#IBAction func next(_ sender: Any) {
let data2 = numbers.text
let storeDetailsVC = self.storyboard?.instantiateViewController(withIdentifier: "storeDetailsVC") as! storeDetailsViewController
storeDetailsVC.data2 = data2!
self.navigationController?.pushViewController(storeDetailsVC, animated: true)
}
}
```

Answer 1

You need to pass the information from text fields to Strings in the next View.
Solution 1:
override func viewDidLoad() {
super.viewDidLoad()
pickUp.text = currentDate // This you can create using the date formatter
dropOff.text = defaultDate // This is default date value you can set if needed
showDatePicker()
}
Solution 2:
#IBAction func didTapNext() {
//Apply validation here to check if its empty if no default value provided.
if dropOff.text.isEmpty {
//Show alert to user to select drof off date.
return
}
if pickUp.text.isEmpty {
//Show alert to user to select PickUp date.
return
}
let dropOff = dropOff.text
let pickUp = pickUp.text
let storeDetailsVC = self.storyboard?.instantiateViewController(withIdentifier: "storeDetailsVC") as! storeDetailsViewController
storeDetailsVC.dropOff = dropOff!
storeDetailsVC.pickUp = pickUp!
}
