Question

I followed this thread: datepicker by clicking on textfield

I imported both of the following protocols:

@interface ViewController : UIViewController&

Here's what I did in Swift 4:

let datePicker = UIDatePicker()
@IBOutlet weak var myTextField: UITextField!

override func viewDidLoad() {
    super.viewDidLoad()
    setDatePicker()
}

func setDatePicker() {
    //Format Date
    datePicker.datePickerMode = .date

    //ToolBar
    let toolbar = UIToolbar();
    toolbar.sizeToFit()
    let doneButton = UIBarButtonItem(title: "Done", style: .plain, target: self, action: #selector(doneDatePicker));
    let spaceButton = UIBarButtonItem(barButtonSystemItem: UIBarButtonItem.SystemItem.flexibleSpace, target: nil, action: nil)
    let cancelButton = UIBarButtonItem(title: "Cancel", style: .plain, target: self, action: #selector(cancelDatePicker));

    toolbar.setItems([doneButton,spaceButton,cancelButton], animated: false)

    myTextField.inputAccessoryView = toolbar
    myTextField.inputView = datePicker
}

@objc func doneDatePicker(){
    let formatter = DateFormatter()
    formatter.dateFormat = "MM/dd/yyyy"
    myTextField.text = formatter.string(from: datePicker.date)
    self.view.endEditing(true)
}

@objc func cancelDatePicker(){
    self.view.endEditing(true)
}
