example of overlay view with UIActivityIndicatorView

Does somebody have a good example of adding an overlay view (that开发者_开发问答 covers the whole screen) with an activity indicator in the middle?

Solved. I created a semi-transparent view in IB with an activity indicator in the middle. I'm adding it to a tabController.selectedView. When done - removing it from there.
