Answer 1

You should get email in this way:

[user objectForKey:@"email"]//Where user is FBGraphUser type

Here is the implementation when login is successful

case FBSessionStateOpen: {

            NSLog(@"accessToken: %@", session.accessTokenData.accessToken);
            [[FBRequest requestForMe] startWithCompletionHandler:
             ^(FBRequestConnection *connection,
               NSDictionary<FBGraphUser> *user,
               NSError *error) {
                 if (error) {
                     //error
                 }else{
                     NSLog(@"%@, %@",[user objectForKey:@"email"], user.description);

                 }
             }];
        }
         break;

Try this :

[facebook authorize:[NSArray arrayWithObjects:@"email",nil]];
