How do I listen for the (x) button in a UITextField?

There's a tiny 🅧 button inside editable text UITextFields that clears the text. I want to listen for this to, say, reset the text "$0.00" instead of "", to close the dialog automatically, etc. How can I listen for this button to be pressed?

A white x inside a gray, filled circle on the right of a text field in an iOS table.

In your text field's delegate, implement textFieldShouldClear:. From the documentation:

The text field calls this method in response to the user pressing the built-in clear button.

UPDATE

It sounds like you want to write this:

- (BOOL)textFieldShouldClear:(UITextField *)textField {
    textField.text = @"";
    [self textFieldDidClear:textField];
    return NO;
}

- (void)textFieldDidClear {
    // To be overridden by subclasses.
}

Don't, instead set your cell as the delegate and when the text is updated to be an empty string you can deny the edit and directly set your text.
