Facebook SDK 3.0: how to receive user's e-mail?

Question

In the \"old\" FB iOS SDK I could receive user information via the following:

NSMutableDictionary *params = [NSMutableDictionary dictionaryWithObjectsAndKeys         


        

Answer 1

if (FBSession.activeSession.isOpen) {
    [[FBRequest requestForMe] startWithCompletionHandler:^(FBRequestConnection *connection, NSDictionary *user, NSError *error) {
         if (!error) {
             self.nameLabel.text = user.name;
             self.emailLabel.text = [user objectForKey:@"email"];
         }
     }];
}

Because FBGraphUser doesn't have an email @property, we can't access the information like with the name (dot-syntax), however the NSDictionary still has the email kv-pair and we can access it like we would do with a normal NSDictionary.

Don't forget to ask for the email permission though:

NSArray *permissions = [[NSArray alloc] initWithObjects:@"email", nil];
[FBSession sessionOpenWithPermissions:permissions completionHandler:
 ^(FBSession *session, FBSessionState state, NSError *error) {
     [self facebookSessionStateChanged:session state:state error:error];
 }];
