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

The easiest method for getting the info after logging in is :

-(IBAction)loginWithFacebook:(id)sender{
FBSDKLoginManager *login = [[FBSDKLoginManager alloc] init];
[login
 logInWithReadPermissions: @[@"public_profile",@"email"]
 fromViewController:self
 handler:^(FBSDKLoginManagerLoginResult *result, NSError *error) {
     if (error) {
         NSLog(@"Process error");
     } else if (result.isCancelled) {
         NSLog(@"Cancelled");
     } else {
         NSLog(@"Logged in");
         [self getFacebookProfileInfos];

     }
  }];
}

-(void)getFacebookProfileInfos {
NSDictionary *parameters = @ {@"fields": @"id, name, first_name, last_name, picture.type(large), email"};
if ([FBSDKAccessToken currentAccessToken]) {
    [[[FBSDKGraphRequest alloc] initWithGraphPath:@"me" parameters:parameters]
     startWithCompletionHandler:^(FBSDKGraphRequestConnection *connection, id result, NSError *error) {
         if (!error) {
             NSLog(@"fetched user:%@", result);
         }
     }];
}

}

You will get all the info the result.
