Answer 1

this will also work

picture.type(large)

example

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


             fbId.text=[data valueForKey:@"id"];
             userName.text=[data valueForKey:@"name"];
             _emailFB.text=[data valueForKey:@"email"];



             NSDictionary *dictionary = (NSDictionary *)result;

             NSDictionary *data3 = [dictionary objectForKey:@"picture"];
             NSDictionary *data2 = [data3 objectForKey:@"data"];
             NSString *photoUrl = (NSString *)[data2 objectForKey:@"url"];

             NSLog(@"Photo : %@",photoUrl);


         }
     }];
}

}
