Hi all,

So I just added a UIActivityIndicator to my app. It works fine but it's not very flashy and there's not always a great place for it on the screen. So, what I would like to do is to make the entire screen much darker and then put the activity indicator right in the middle, as I know I've seen that elsewhere.

Does anyone know of a way to do this?

Thanks for any suggestions?
