Get users email from Fackbook - facebook

Question

I have just made a new app and I have it all set up with Facebook login, and I have been approved for the email permission, but I seem to not to be getting the users email, I think I might be missing something in my code here is what I have:
// Set permissions required from the facebook user account
NSArray *permissionsArray = #[ #"user_about_me", #"user_relationships", #"user_likes", #"user_location", #"email", #"basic_info", #"user_activities", #"user_interests", #"user_birthday"];
// Login PFUser using facebook
[PFFacebookUtils logInWithPermissions:permissionsArray block:^(PFUser *user, NSError *error) {
if (!user) {
if (!error) {
NSLog(#"Uh oh. The user cancelled the Facebook login.");
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"Log In Error" message:#"Uh oh. The user cancelled the Facebook login." delegate:nil cancelButtonTitle:nil otherButtonTitles:#"Dismiss", nil];
[alert show];
} else {
NSLog(#"Uh oh. An error occurred: %#", error);
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"Log In Error" message:[error description] delegate:nil cancelButtonTitle:nil otherButtonTitles:#"Dismiss", nil];
[alert show];
}
} else if (user.isNew) {
user[#"school"] = #"";
NSLog(#"User with facebook signed up and logged in!");
}
else {
NSLog(#"User with facebook logged in!");
}
}
}];
If you could show of tell me what I am missing/ why I am not seeing my users email. I would really appreciate it. By the way I am using Parse.com as a backend.

logInWithPermissions: method doesn't save the email attribute by default when it creates a new user. If you want to save the email of a Facebook user, after verifying that the user is already authenticated, you need to call startForMeWithCompletionHandler: method of FBRequestConnection class. Your code should look like this in the last part:
NSLog(#"User with facebook logged in!");
[FBRequestConnection startForMeWithCompletionHandler:^(FBRequestConnection *connection, id result, NSError *error) {
if (!error) {
[[PFUser currentUser] setObject:[result objectForKey:#"email"]
forKey:#"email"];
[[PFUser currentUser] saveInBackground];
}
}];
