Status update field blank using @"message" in the latest Facebook API

I am building a demo app where I can upload random jokes generated via the app. My code was working fine before 12th August 2011, updated facebook api. Now Facebook has a policy that you cannot automate the status updates via apps, the user should write the status update ? How do I get a work around for this ?

NSMutableDictionary* params = [NS开发者_如何学JAVAMutableDictionary dictionaryWithObjectsAndKeys:
  kAppId, @"app_id",

  MainTextView.text,  @"message",
  nil];

[_facebook dialog:@"feed" andParams:params andDelegate:self];

This is what I used and use to work perfect . I have also tried stream.publish .

You need to have publish_stream to create a post on a user's wall. If you're trying to create a post when the user is not directly logged in to your app, you also need the offline_access permission.

This blog post details changes made on August 12th. I don't see anything that would have broken your app's ability to post status messages. It's more likely you are really dealing with a permissions issue.

The "policy that you cannot automate the status updates" is more of a guideline. In the documentation for the publish_stream permission this is what they say (emphasis added):

Please note that Facebook recommends a user-initiated sharing model.

Meaning they recommend against posting automated messages to a user's wall. But they have no way of detecting whether a user initiated the post in your app or not, so they leave it up to you to be a responsible citizen.

It's really simple:

POST to https://graph.facebook.com/user-id/feed the key-value pair "message":"A rabbit walks into a bar..." Your application must have the publish_stream permission.
