Shouldn't it be [self setDelegate: self]? I wouldn't think you'd
have an actual 'super' object available to perform the delegate
methods.
But I probably don't understand.

The reason is simple, though probably not obvious.
I still might need the text field to have an "outside" delegate, which
I maintain by having an additional outlet reserved for that delegate.
Then, I override -delegate to return that outlet and -setDelegate: to
set it.
That way, the field can be its own true delegate and do its job, while
also allowing an outside object to serve as a delegate and participate
in the editing session. As far as the outside world is concerned, it's
business as usual.
But once I have an overridden -setDelegate:, I can't use self.delegate
= self to set the field as its own true delegate, because that will
execute the overridden method.
