ใช้func textField(_ textField: UITextField, shouldChangeCharactersIn range: NSRange, replacementString string: String) -> Bool { retrun bool }แทนtextFieldShouldBeginEditing.
class ViewController: UIViewController , UITextFieldDelegate {
@IBOutlet weak var textField: UITextField!
override func viewDidLoad() {
super.viewDidLoad()
//Show date picker
let datePicker = UIDatePicker()
datePicker.datePickerMode = UIDatePickerMode.date
textField.tag = 1
textField.inputView = datePicker
}
func textFieldShouldBeginEditing(_ textField: UITextField) -> Bool {
if textField.tag == 1 {
textField.text = ""
return false
}
return true
}
func textField(_ textField: UITextField, shouldChangeCharactersIn range: NSRange, replacementString string: String) -> Bool {
if textField.tag == 1 {
textField.text = ""
return false
}
return true
}
}
