我正在使用 FBDialogs 在 facebook 上分享图片、名称和描述。以下是我用于共享的代码：-

[FBDialogs presentShareDialogWithLink:params.link
                                     name:params.name
                                  caption:nil
                                  description:[NSString stringWithFormat:@"OMG I’m in LOVE with a puppy named %@.Come and say hi %@",sPuppyName , ITUNES_STORE_LINK]
                                  picture:params.picture
                              clientState:nil
                                  handler:^(FBAppCall *call, NSDictionary *results, NSError *error) {
                                      if(error) {
                                          // An error occurred, we need to handle the error
                                          // See: https://developers.facebook.com/docs/ios/errors
                                          NSLog(@"Error publishing story: %@", error.description);
                                      } else {
                                          // Success

                                          NSLog(@"result %@", results);
                                          NSLog(@"result obtained %@",[results valueForKey:@"completionGesture"]);
                                          if([[results valueForKey:@"completionGesture"] isEqualToString:@"cancel"]){

                                         [[NSNotificationCenter defaultCenter] postNotificationName:@"facebookDidSharingCancel" object:self userInfo:nil];
                                          }
                                          else if([[results valueForKey:@"completionGesture"] isEqualToString:@"post"])
                                        {
                                               [[NSNotificationCenter defaultCenter] postNotificationName:@"facebookDidLogin" object:self userInfo:nil];

                                          }  
                                      }
                                  }];

分享时我可以在分享对话框上看到描述，但在 Facebook 网站上我看不到描述。搜索了很多，但找不到任何方法，所以请任何人帮助我。提前致谢
