Step 3 : The function pickUp to create UIPickerView with ToolBar. 
func pickUp(_ textField : UITextField){

    // UIPickerView
    self.myPickerView = UIPickerView(frame:CGRect(x: 0, y: 0, width: self.view.frame.size.width, height: 216))
    self.myPickerView.delegate = self
    self.myPickerView.dataSource = self
    self.myPickerView.backgroundColor = UIColor.white
    textField.inputView = self.myPickerView

    // ToolBar
    let toolBar = UIToolbar()

//MARK:- PickerView Delegate & DataSource
func numberOfComponents(in pickerView: UIPickerView) -> Int {
    return 1
func pickerView(_ pickerView: UIPickerView, numberOfRowsInComponent component: Int) -> Int {
    return pickerData.count
func pickerView(_ pickerView: UIPickerView, titleForRow row: Int, forComponent component: Int) -> String? {
    return pickerData[row]
func pickerView(_ pickerView: UIPickerView, didSelectRow row: Int, inComponent component: Int) {
    self.txt_pickUpData.text = pickerData[row]
//MARK:- TextFiled Delegate
