Could you do something like this:

- (UIFont*)textFont {
  if (!_textFont) {
    _textFont = [[MDFRobotoFontLoader sharedInstance] mediumFontOfSize:14];
  }
  return _textFont;
}

That way the default value can be reset easily by setting textFont to nil (which
is exactly the behavior of a null_resettable property).

Done.
