iOS facebook 集成 - 发送和接收请求

Question

我使用 facebook api 连接到 facebook 并通过 api 提供的 native 对话框发送请求。

我按照developers.facebook.com上的文档中发布的示例进行操作但我在发送请求时遇到以下问题: 1.请求未显示在通知中 - 仅在应用程序中心中 - 在这种情况下，我认为问题在于应用程序位于沙箱中并且未发布到应用程序商店

1. 我成功使用正确的 fbUser ID 向 facebook 服务器发送请求。但是当我想在应用程序中接收通知时，问题就来了:

作为授权用户，我应该遵循文档这在打开网址方法中:

fb[APP_ID]://authorize#expires_in=[ACCESS_TOKEN_EXPIRATION]
    &access_token=[USER_ACCESS_TOKEN]
    &target_url=https://apps.facebook.com/[APP_NAME_SPACE]/?request_ids=
    [COMMA_SEPARATED_REQUESTIDs]&ref=notif&app_request_type=user_to_user

但我只能看到没有目标网址的普通登录...我可以看到 session 到期日期、fb 应用程序 ID、访问 token 等。但没有目标网址？

那么 target_url 基本上是什么？应该如何设置呢？发送请求时我必须包含什么？

此外:应用程序句柄 open url 方法被正确调用。应用程序激活后也会正确调用 checkRequests 方法。

请不要将我链接到文档。我读了不到50遍，没有找到任何合理的解决方案......

                    // request id endpoint
                    [self notificationGet:[requestIDs objectAtIndex:0]];
                }
            }
            // Clean out to avoid duplicate calls
            self.openedURL = nil;
        }
    }

这些问题是否有可能是由于应用程序未在Appstore上发布(iPhone和iPad均未设置Appstore id)导致的？
