// Show the feed dialog
[FBWebDialogs presentFeedDialogModallyWithSession:nil
                                   parameters:params
                                      handler:^(FBWebDialogResult result, NSURL *resultURL, NSError *error) {
                                        if (error) {
                                         //error
                                        } else {
                                          if (result == FBWebDialogResultDialogNotCompleted) {

                                          } else {
                                            // Handle the publish feed callback
                                            NSDictionary *urlParams = [self parseURLParams:[resultURL query]];

                                            if (![urlParams valueForKey:@"post_id"]) {
                                              // User cancelled.


                                            } else {
                                              // User clicked the Share button
                                              NSString *result = [NSString stringWithFormat: @"Posted story, id: %@", [urlParams valueForKey:@"post_id"]];

                                            }
                                          }
                                        }
                                      }];

when I remove or change link parameter, sharing done perfectly.
