No. You have no access to any account details. The most you can do is
- Find out if iCloud is configured by calling
[NSFileManager ubiquityIdentityToken]
- Find out if the account has changed by calling that method again to see if the value has changed or by observing
NSUbiquityIdentityDidChangeNotification
.
You do not get to find out the user's account name or any other details about their account. None of that is relevant to using iCloud.
