How to find user SID in objective-c

Question

I am using objective-c for the first time.

My requirement is to authenticate the logged in user and find their SID.

In windows development we have a very few APIS, with the help of which we can find out the SID of the user.

My assumption is: there should be some functions in the cocoa framework which should tell us the SID of the user.

If there is no such feature, then how else should I try to find it?

Guide me on this.

I think it's a unique identifier for the device.

This open source project helps you get that:

UIDevice-with-UniqueIdentifier-for-iOS-5

From the documentation:

use [[UIDevice currentDevice] uniqueDeviceIdentifier] to retrieve the unique identifier (it's a hash of your Bundle ID + MAC address)

use [[UIDevice currentDevice] uniqueGlobalDeviceIdentifier] to retrieve a global unique identifier (it's a hash of the MAC address, used for tracking between different apps).
