iOS Facebook集成-发送和接收请求

Question

I use a facebook api to connect to facebook and send request via native dialogs provided by the api.

I followed the sample posted in the docs on developers.facebook.com But I have following problem sending requests : 1. The requests are not shown in notifications - only in application center - In this case i think that it is a problem of that the app is in sandbox and not posted to APPSTORE

1. I succesfully send request to facebook server with right fbUser id. But when I want to receive the notification in app here comes the problem :

Following the docs as an authorized user I should se this in open url method:

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

But i can see only plain login without targer url .... I can see session expiration date, fb app id, access token and so on. But no target url?

So basically what the target_url is? How it should be set? What i have to include when sending request?

In addition : application handle open url method is called properly. checkRequests method is also called properly after app becomes active.

Please do not link me to the docs. I have read it moreless 50 times and didn't find any reasonable solution...

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

Is there any way that these problems are caused by the way that the app is not published on Appstore (Appstore id is not set neither for iPhone nor iPad)?

Here are code snippets showing using of the fb api:
