Well, it's the usual approach. The content view is something that
the window
owns to act purely as the root of its view hierarchy - there's
usually not
much to be gained by fiddling with it or putting your own content
there
directly. For example, when you drag a custom view (or any view)
into a
window in Interface Builder, it's actually adding it as a subview
of the
implied contentView, which you never see in IB.
In fact I would go so far as to say that if you ever use
-setContentView:, you are very probably doing it wrong. It is, for the
most part, not a very useful call, and you can accomplish the same
thing more naturally, easily, and flexibly by adding the view as a
subview to the content view instead.
Well, I would not go quite that far, although I agree with you
in principle for normal everyday stuff. I have some applications
which create bare windows --- no borders, controls, resizers,
shadows, and so on. The view that replaces the default window
content view does all the drawing. I don't see any value in
having a content view whose only purpose in life is to act as
a container for my drawing view.
But I agree that these are unusual cases . . .
