How to get user's email with Facebook SDK 3.1 on iOS?

I'm opening the facebook session with the email permission like so:

- (void)facebookOpenSession {
    NSArray *permissions = @[@"email"];
    [FBSession openActiveSessionWithReadPermissions:permissions
                                  completionHandler:^(FBSession *session, FBSessionState state, NSError *error) {
        [self sessionStateChanged:session state:state error:error];

And then the important snippet of session state changed looks like:

- (void)sessionStateChanged:(FBSession *)session
                      state:(FBSessionState) state
                      error:(NSError *)error {
    switch (state) {
        case FBSessionStateOpen: {
            [[FBRequest requestForMe] startWithCompletionHandler:^(FBRequestConnection *connection, NSDictionary<FBGraphUser> *user, NSError *error) {
             if (error) {
             } else {
                 self.myFirstNameLabel.text = user.first_name;
                 self.myLastNameLabel.text = user.last_name;
                 // self.myEmailLabel.text = @"";

How do I actually extract the user's email? Is it in one of the provided variables, or do I have to make another call within the completion handler?

Thanks in advance!


FBGraphUser doesn't have the property (i'm assuming because its optional/only available if you asked for the email permission) but you should still be able to access it from the dictionary like this:

[user objectForKey:@"email"]

You should check before yo ask the right permissions

loginView.readPermissions = @[@"public_profile", @"email"];

How can you check if a network socket (System.Net.Sockets.Socket) is still connected if the other host doesn't send you a packet when it disconnects (e.g. because it disconnected ungracefully)?
