How could I get the user number who accept 3rd party cookies?

Hi,

I want to know visitor's cookie statement with SiteCatalyst.

I have read the tips using the User Report with checking the Non-persistent cookie Visitor option.

But someone told me that report was not enough to know users who rejected 3rd party cookies like as iPhone users.

Could you advise me  how to get that data?
