You can set yourself as the text field delegate and implement textField:shouldChangeCharactersInRange:replacementString:. If the range is the full range of the textField.text and the replacement string is equal to @"" then it is a clear operation.

Note that the user manually selecting all text and hitting backspace on the keyboard will have the same result.
