So why is it that when the standard sheet for presentError: is
displayed, it only ever uses NSLocalizedDescriptionKey and
NSLocalizedRecoverySuggestionErrorKey? A lot of NSError objects don't
have a value for NSLocalizedRecoverySuggestionErrorKey but they do
have values for NSLocalizedFailureReasonErrorKey. Instead of using the
failure reason, the sheet just doesn't show anything at all and only
uses the description.
It's pretty silly to only show _some_ of the information available,
but the other silly thing is that if I want to use presentError: to
display an NSError object, I have to supply the *reason* something
failed with NSLocalizedRecoverySuggestionErrorKey so that the reason
actually is displayed, despite the fact it's a failure reason and not
a recovery suggestion.
I could write my own method, and I suppose I probably should, but
given there's existing methods and callbacks for the presentError:
path, I wonder why it doesn't work as I think it should.
