FBConnect iOS SDK publish_action Issue - objective-c

Question

I must say I feel like an idiot right now. :) I've been up and down Facebook, Google and StackOverflow and still cannot get the answer to what I am doing wrong! :) I've looked at both Facebook examples: Hackbook and WishList. Wishlist is obviously the one that should tell me what to do, but ALL the examples I've seen have the OBJECT part as a URL. I do not necessarily desire this, as I just want the post to say (this user) is playing [MyGame].
Ok here's my goal. I have an iPhone game. I want to do what Spotify does when you listen to a song, which posts to timeline and ticker. I'd also like to use this to post the player's score on the user's timeline and ticker.
I setup Open Graph with an action called Play and an object called Game along with it's aggregator. I think I also will need an action called Score?
Anyways, I can successfully post to a user's wall using feed dialog, but that's not what I want for the Play action.
Here's a concise version of what I got so far, any help is much appreciated:
Couple Notes:
I have a singleton FacebookInfo which takes care of handling Facebook delegates and stuff. I also have a FacebookUser class which hold the current user's info for the current session, populated when calling me. I also have a DLog method which simply does an NSlog only on debug mode.
When a user clicks the Play button in my game, I would like to call my method [[Facebook sharedInfo] publishAction:#"play"] below. I'm passing an NSString as action so later I can call the same method and use an action like Score and just modify the post accordingly.

Wow, I know this is a long post, but I hope someone can help point me in the right direction.
UPDATE 1: (2012/18/02)
Ok. So I settled for making a page which contains the og meta-data which I did not want to do and supplied the url for my object. As per the FB Documentation, found here:
Open Graph Mechanics
When users take an action in your app, such as cook the Stuffed Cookie, the app calls a Graph API to create a new cook action that connects the user with the Stuffed Cookie object. This is accomplished by issuing a HTTP POST to the user’s /me/myapp:cook connection with the URL of the recipe object. Facebook will then crawl the object URL, read the metadata, and connect the object to user's Graph via the action.
The diagram below illustrates the process:
User takes an action in the app, such as "cook" a "recipe"
App calls a Graph API /me/action:object=Object_URL
Facebook will crawl the object URL, read its meta tags and connects the object to the user's Graph via the action.
It would be cool if we can define these things in the app itself as params for cases where I do not need a website for.

Answer 1

As of 4/21/12 Facebook requires you to have created a page to get the data desired.
