UITextField text change event

Question

How can I detect any text changes in a textField? The delegate method shouldChangeCharactersInRange works for something, but it did not fulfill my need exactly.

Answer 1

Swift 3 Version

yourTextField.addTarget(self, action: #selector(YourControllerName.textChanges(_:)), for: UIControlEvents.editingChanged)

And get the changes in here

func textChanges(_ textField: UITextField) {
    let text = textField.text! // your desired text here
    // Now do whatever you want.
}

Hope it helps.
