New Category tag for Actionable Notification

[GoogleCodeExporter]

Hi,
How to add a new tag along with existing alets,badgeNo & message tags?In latest 
IOS8 actionable notifications are introduced,for that i need to send a tag 
named Category along with some value in payload to APNS. 
Eg:
  aps =     {
            alert = "New Emergency task has been dispatched : MTRREAD";
            badge = 1;
            sound = "longalert.wav";
category = myCategory;
        };
