How can I use the same function to handle DatePickerView on 2 different textFields?
To avoid repetition, I would like to set up 2 textFields with a DatePicker. One field is for issue date and the other one for due date.
When I try to add parameter on @objc func doneClick, I got a compiler error ==> Instance member 'doneClick' cannot be used on type 'InvoiceViewController'; did you mean to use a value of this type instead?
import UIKit
class InvoiceViewController: UIViewController, UITextFieldDelegate{
var thePicker = UIDatePicker()
@IBOutlet weak var dateIssueTextField: UITextField!
@IBOutlet weak var dueDateTextField: UITextField!
@objc func doneClick(textField: UITextField!) {
let dateFormatter = DateFormatter()
dateFormatter.dateStyle = .short
dateFormatter.timeStyle = .none
dateIssueTextField.text = dateFormatter.string(from: thePicker.date)
dateFormatter.dateFormat = "yyyy"
let year: String = dateFormatter.string(from: self.thePicker.date)
dateFormatter.dateFormat = "MM"
let month: String = dateFormatter.string(from: self.thePicker.date)
dateFormatter.dateFormat = "dd"
let day: String = dateFormatter.string(from: self.thePicker.date)
let finalDate = year+"-"+month+"-"+day
print(finalDate)
// dateIssueTextField.resignFirstResponder()
textField.resignFirstResponder()
}
@objc func cancelClick() {
dateIssueTextField.resignFirstResponder()
}
func setUpTextFieldPicker(textField: UITextField) {
// DatePicker
self.thePicker = UIDatePicker(frame:CGRect(x: 0, y: 0, width: self.view.frame.size.width, height: 216))
self.thePicker.backgroundColor = UIColor.white
self.thePicker.datePickerMode = UIDatePickerMode.date
// dateIssueTextField.inputView = thePicker
// dueDateTextField.inputView = thePicker
textField.inputView = thePicker
// ToolBar
let toolBar = UIToolbar()
toolBar.barStyle = .default
toolBar.isTranslucent = true
toolBar.tintColor = UIColor(red: 92/255, green: 216/255, blue: 255/255, alpha: 1)
toolBar.sizeToFit()
// Adding Button ToolBar
let doneButton = UIBarButtonItem(title: "Done", style: .plain, target: self, action: #selector(InvoiceViewController.doneClick))
let spaceButton = UIBarButtonItem(barButtonSystemItem: .flexibleSpace, target: nil, action: nil)
let cancelButton = UIBarButtonItem(title: "Cancel", style: .plain, target: self, action: #selector(InvoiceViewController.cancelClick))
toolBar.setItems([cancelButton, spaceButton, doneButton], animated: false)
toolBar.isUserInteractionEnabled = true
//dateIssueTextField.inputAccessoryView = toolBar
//dueDateTextField.inputAccessoryView = toolBar
textField.inputAccessoryView = toolBar
