var activeTextField = UITextField()
// Assign the newly active text field to your activeTextField variable
func textFieldDidBeginEditing(textField: UITextField) {
self.activeTextField = textField
}
// Call activeTextField whenever you need to
func anotherMethod() {
// self.activeTextField.text is an optional, we safely unwrap it here
