If an app is a client of NSNetServiceBrowser, and attempts to search for services while the local network access permission is not granted for that app, will there be a specific error or notification? Will the app be able to determine the reason why no services were found? Or will this case be undistinguishable, from the app's point of view, from the case where the permission is granted but no services were found on the network?
