Stop Animation doesn't work when viewControllers are presenting/dismissing

[Mehrdadmaskull]

Steps to reproduce:
Have a tableView in a viewController, add the loading, go to another viewController, do something network-related, add another loading, stop the loading animation after you receive a response, call a delegate method back and dismiss the current viewController, stop the animation in the delegate method, nothing happens.

I dug into the code and changed the following inside hide() method inside NVActivityIndicatorPresenter.swift from

for item in UIApplication.shared.keyWindow!.subviews
    where item.restorationIdentifier == restorationIdentifier {
        item.removeFromSuperview()
}

to

for window in UIApplication.shared.windows {
    for item in window.subviews
        where item.restorationIdentifier == restorationIdentifier {
            item.removeFromSuperview()
        }
}

and it works. Is there any reason why keyWindow is used instead of windows?

@Mehrdadmaskull: keyWindow is used to add overlay view on top-most window so that it covers all beneath views. In your case, I guess that going to another view controller creates a new window on top of the one you added the loader. You could try debugging windows to see if there's new window added.

Close this, reopen if need be.
