How to show the loading indicator in the top status bar

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?

Solution

  • 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
