Facebook request does not return email

No email is outputted from the Facebook request. How do I get this? I need it for my login/signup process

- (void)request:(FBRequest *)request didLoad:(id)result{

    NSLog(@"FACEBOOK RESULT %@ ", result);

}

This is the initial request:

[facebook requestWithGraphPath:@"me" andDelegate:self];

With 2.4 api, parameters are used in order to specify which user data items you are interested in receiving. E.g.:

FBSDKGraphRequestConnection *connection2 = [[FBSDKGraphRequestConnection alloc] init];

FBSDKGraphRequest *selfRequest = [[FBSDKGraphRequest alloc] initWithGraphPath:@"me?"
                                                                   parameters:@{@"fields":@"id,name,first_name,last_name,verified,email"}];
[connection2 addRequest:selfRequest
      completionHandler:^(FBSDKGraphRequestConnection *innerConnection, NSDictionary *result, NSError *error) {
          if (error) {
              NSLog(@"%@", error);
              return;
          }

          if (result) {
              // get user data
              NSMutableDictionary *facebookUserData = [NSMutableDictionary dictionaryWithDictionary:result];
              NSLog(@"result=%@", result);

HOWEVER, they apparently messed up big time, as email is NOT CURRENTLY being returned for DEVELOPERS, and currently in development Apps. Incidentally, it is IMPOSSIBLE to submit bugs on Apps in development, as they require approved apps in the feedback system...

I wonder how do they think we are going to make sure that something works BEFORE submitting an app for approval, or what is the logic of asking for an App Store id of an App which can't be approved BEFORE Facebook integration can be tested to the fullest.

Besides, who is the genius at Facebook who decides to break working code one day from another?

The email property cannot be obtained without requesting additional permission to obtain it, see https://developers.facebook.com/docs/reference/login/email-permissions/.

My application uses the following code to first check whether the Facebook session is valid (self.facebook is a Facebook object initialized with initWithAppId):

  if (![self.facebook isSessionValid]) { 

    NSArray* permissions =  [NSArray arrayWithObjects: @"email", nil];

    [self.facebook authorize:permissions];

  } else { 
    // Since we have a valid session we can get the userinfo
    [self getFacebookUserInfo];
  }

Your application prompt will indicate "Using this app requires: * Your basic info * Your e-mail address" If the user authorizes you to obtain this information your access token returned will have bits in set to allow you to obtain the e-mail address, and the following will work:

-(void)getFacebookUserInfo {
  [self.facebook requestWithGraphPath:@"me" andDelegate:self];
}

assuming your -(void)request:(FBRequest *)request didLoad:(id)result method is available (which it appears that it is).

Note that the full flow of SSO (Single Sign On) is not given here in this post, you'll need to go through https://developers.facebook.com/docs/tutorials/ios-sdk-tutorial/#implementsso in detail.

Note also that you may be using a deprecated API for iOS 6, you should look at https://developers.facebook.com/docs/tutorial/iossdk/upgrading-from-2.0-to-3.1/ before going further.
