Hi,
I'd like to display a busy indicator view (HUD) regardless of whatever
view is currently at the top of the view stack. I'd also like this
view to display modally so that the user interface beneath it is dead
to touch events. This is like Tweetie 2's HUD that appears when you've
successfully posted something to Instapaper, with the difference that
the UI underneath it wouldn't accept events as they do in Tweetie 2.
I'd also like to have some control over animating the HUD onto and off
of the screen.
My current thinking is to find the topmost view controller somehow and
send it presentModalViewController:animated:. However, I don't know
how much control over animation I'd get with that method as the built-
in animation styles sort of assume a full screen view. Also, I've
never tried to use this method with a view that's smaller than the
screen size.
Another thought is to just add the view to the root view and bring it
to the top (this however won't make the view modal as the views below
will still respond to touch events).
Can anyone tell me if I'm thinking along the right directions? I'd
like to have some confirmation before I invest a bunch of time only to
find out it's the wrong method.
Thanks,
Mike Manzano

Oh BTW, the first reply that gets me closer to a solution gets a free

Google Reader client for iPhone/iPod touch that I just released ;)
