How can I reduce performance in an iPhone application?

I saw many iPhone apps that will dim on the screen with an activity indicator when it updates or loads something so that the user knows that he is busy. I know how to make an indicator of activity, but how can I lose weight? Please send an example code if you can.

Well, the way I did this was too big to create another view and set the opacity very low. Then I add this view as a preview.
