Change the status of the notification center in iPhone programmatically or atleast read what the status is for a particular application

Question

Is it possible to control and change the status of the notification center in iPhone for a particular application.
1)      In the application push notification is implemented.
2)      Once this application is installed we can see the app in the notification center.
3)      There is an option to ON or OFF
4)      In the application we need an option to check if the above option is ON or OFF.
5)      If the option is OFF we need to provide the user an alert stating that  in the notification center has it option off and here we have to provide an option to user to switch ON the option at the notification center.

Answer 1

Well, I could find a fix for that.
My mistake was that 1: I wasn't getting the correct ntype code for my value list type. And 2: I wasn't giving the Id name.
The new result came as this:
statusObjRef = doc.getStatusRef();
statusHome = IBeanHomeLocator.lookup(session,statusObjRef);
status = statusHome.findUniqueByNameType("Drafting Agreement", 1);
doc.setStatusRef(status.getObjectReference());
In case anyone has this problem, you should check the collection of values internal id, that's the actual ntype code (the number you send on the second parameter).
But I could still use help having some advice on the Master Agreement elements handling (getting data from the master agreement or the data thas is being edited at the moment before saving).
If anyone could give some advice, they would be very welcome
