All right, let's discuss the network activity indicator. Now, we touch the topic of a network activity indicator briefly in the status bar lecture. So, a network activity indicator appears in the status bar and shows that network activity is occurring. Wow. All right. Display the network activity indicator to provide feedback when your app accesses the network for more than a couple of seconds.

If the operation finishes sooner than that, sooner than two seconds, you don't have to show the network activity indicator because the indicator is likely to disappear before users even notice its presence. network activity indicator just spins in the status bar while network activity proceeds and disappears when network activity stops. It doesn't allow user interaction. That's it about this great UI element.
