Can anybody help me get my head around how the registration process
for custom value transformers is supposed to work? I've read the
docs etc. but I'm still not entirely clear.
First, how many instances of my transformer should there be in the
app. Say I have multiple document windows and each one has one
interface element that uses the transformer, should I have an
instance for each of the interface elements, or is there a single
instance that all the elements share?
Of course, my real question, is when do I carry out this
"registration"? The docs just say in the app's delegate, but I don't
really get which delegate method I should be doing this in. I guess
things also depend my above question.
Thanks,
Mike.
