Question

Can you help with some stuck here, let’s look on code first,
here i ask for permissions

 NSMutableDictionary *params = [[NSMutableDictionary alloc] initWithCapacity:0];
    [params setObject:facebook._appId forKey:@"client_id"];
    [params setObject:@"token" forKey:@"response_type"];
    [params setObject:[NSString stringWithCString:"email,user_about_me,read_stream,publish_stream,offline_access" encoding:NSUTF8StringEncoding] forKey:@"scope"];
    [facebook dialog:@"oauth" andParams:params andDelegate:self];
    [params release];

Here use @”me” for graph API

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

}

But all what i get is

- (void)request:(FBRequest *)request didLoad:(id)result
{
    [UIApplication sharedApplication].networkActivityIndicatorVisible=NO;
    NSLog(@"FB result %@", result);
}

FB result (
“Justfortest Workingin”,
100002369945695
)

But how to get email address ?

Answer 1

The correct answer was that fb not return email and other data with

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

only id and name.

I need to simply put in

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

another call for user data.

Finally needed method looks like this:

    - (void)request:(FBRequest *)request didLoad:(id)result
    {
        NSData * dt = [NSData dataWithContentsOfURL:[NSURL URLWithString:[NSString stringWithFormat:@"https://graph.facebook.com/me/?access_token=%@",facebook.accessToken]]];
        NSDictionary *response = (NSDictionary*)[[JSONDecoder decoder] objectWithData:dt];
        NSLog(@"fb response %@",response);
        if ([response objectForKey:@"email"]) {
            [[NSUserDefaults standardUserDefaults] setValue:[response objectForKey:@"email"] forKey:@"fbEmail"];
            [[NSUserDefaults standardUserDefaults] setValue:[response objectForKey:@"id"] forKey:@"fbId"];
            [[NSUserDefaults standardUserDefaults] setValue:facebook.accessToken forKey:@"fbToken"];
            [[NSUserDefaults standardUserDefaults] setValue:facebook.expirationDate forKey:@"fbExDate"];
            [[NSUserDefaults standardUserDefaults] synchronize];
        }
    }

And i got all user data, thx to all for help, hope this will be helpful for someone.
