Question

Is there a way to detect if a UITextField exists using the Tag property? Essentially i have a number of textfields created dynamically and I want to tab through the fields using the return key on the keypad.

I am trying to use the below code form another post but ‘textField.superview’ returns null. I am creating the textfields programatically.

-(BOOL)textFieldShouldReturn:(UITextField*)textField;
{
  NSInteger nextTag = textField.tag + 1;
  // Try to find next responder
  UIResponder* nextResponder = [textField.superview viewWithTag:nextTag];
  if (nextResponder) {
    // Found next responder, so set it.
    [nextResponder becomeFirstResponder];
  } else {
    // Not found, so remove keyboard.
     [textField resignFirstResponder];
  }
  return NO; // We do not want UITextField to insert line-breaks.
}

You can directly check like this

       -(BOOL)textFieldShouldReturn:(UITextField*)textField {
             if (textField.tag == 1) {
             //Do the stuff what you want here
             }
        }

For setting the tag

        textFieldName.tag = 1;
