Since access to the UUID is deprecated under iOS there is the need to have a Unique identifier per device, one way is to use the MAC adress of the first interface.
- Copy the ShowMAC.m and ShowMAC.h into your Xcode Project, probably the best place would be Plugins
- Copy the JS file in your www directory and include it in your html to use it
- call from JS (with jQuery) via
$(document).bind('deviceready', function(){ window.plugins.showmac.get( function(m){ console.log("Device MAC Address is" + mac); } ); });
