title: Is there an event for disconnecting from the internet on iOS?
body: <p>I have an application that requires an internet connection for a certain library I use (XIMSS for Communigate). It receives status updates from a server and I can't alter the source of the lib. Is there a way to detect that the device disconnected from the internet? I'd like to avoid having to ping a server every x seconds to see if there is still a connection.</p>
