ios - How to show the loading indicator in the top status bar

Question

I have noticed that some apps like Safari and Mail show a loading indicator in the status bar (the bar at the very top of the phone) when they are accessing the network. Is there a way to do the same thing in SDK apps, or is this an Apple only thing?

Answer 1

It's in UIApplication:

For Objective C:

Start:

[UIApplication sharedApplication].networkActivityIndicatorVisible = YES;

End:

[UIApplication sharedApplication].networkActivityIndicatorVisible = NO;

For swift :

Start

UIApplication.shared.isNetworkActivityIndicatorVisible = true

End

UIApplication.shared.isNetworkActivityIndicatorVisible = false
