Hi,
How to handle Date in TextField with all validations?
suppose if my date format is DD/MM/YYYY HH:mm,
and when i type the date ,for example 10
it should add /
and when i type month ,for example 10/12
it should add /
and when i type year ,for example 10/12/2019
it should add a space
and when i type the hour,for example 10/12/2019 10
it should add a colon
and then i can type the minutes like 10/12/2019 10:10
My code Snippet:
In textfield delegate method , shouldChangeCharactersIn ,
func textField(_ textField: UITextField, shouldChangeCharactersIn range: NSRange, replacementString string: String) -> Bool {
if textField.text?.count == 1 {
textField.placeholder = "DD/MM/YYYY HH:mm"
}
if (textField.text?.count == 2) || (textField.text?.count == 5) {
//Handle backspace being pressed
if !(string == "") {
txtValue.text = textField.text! + "/"
}
}else if (textField.text?.count == 10) {
if !(string == "") {
txtValue.text = textField.text! + " "
}
}else if (textField.text?.count == 13) {
if !(string == "") {
txtValue.text = textField.text! + ":"
}
}
return !(textField.text!.count > 15 && (string.count) > range.length)
}
The problem is ,
when backspace tapped from inbetween the date in the textfield,it should validate the date.How to handle this?
