ACAccount Facebook property username return email and sometimes the nickname

Question

When I access to the Facebook Account using ACAccountStore to get an ACAccount object I noticed that for some profiles the ACAccount.username give me the Facebook email but for other profiles give me the nickname... How is possible that the same property contains different value ?

This drive me crazy...

Yes, it's weird for me too. But I can get the email from properties field like below:

NSString *email = [[account valueForKey:@"properties"] objectForKey:@"ACUIDisplayUsername"];
