We’ve recently had a hell of a time hiring someone, who is expert in using the Facebook “graph”

You would usually do Facebook functions in a Unity app – iOS 6.0 – using the Prime31 SocialNetworking plugin.

So I want someone to please show here precisely how you would do it.

Pls do not attempt this unless you are totally familiar with Facebook “apps”, the appid / shared secret concept on facebook apps, you must be completely familiar with using Prime31’s SocialNetworking plugin (or at least their other plugins), and of course you are familiar with the joys of the FB “graph” API etc.

Pls note that this has nothing to do with a URL link. In iOS6, users can be logged in to the inherent FB system that is now in iOS on the control panel, and then by using (typically) the Prime31 Plugin, you can then access, with that actual authorized FB user, the FB “graph” - and you can thus directly, within the app, do things like Like buttons (and indeed much much more).

So it will be a nice little but of open source, and if you know what you’re doing claim the reward!!!

Cheers!

Have you seen any apps that actually do this? Every one I’ve looked at opens up the Facebook page of the item you want to like either inside the facebook app or safari.

The following code will allow you to like objects that facebook allows (this does not include pages or apps).

public void Like(string likeID)
{
   Facebook.instance.graphRequest(
          likeID+"/likes",
          HTTPVerb.POST,
          ( error, obj ) =>
   {
     if (obj != null)
     {
      Prime31.Utils.logObject( obj );
     }
     if( error != null )
     {
      Debug.Log("Error liking:"+error);
      return;
     }
     Debug.Log( "like finished: " );
   });
}

So for example the following will successfully like our upcoming game’s picture:

if (GUILayout.Button( "Like Stuntman Eddie" ) )
{
   Like("563245350362153");
}

however the following will return failure trying to like our company page

if (GUILayout.Button( "Like Tactile Fusion" ) )
{
   Like("447312341955455");
}

If the above are not suitable then you can forcibly open the page in the facebook app it’s self via:

	if (GUILayout.Button( "Open Tactile Fusion Page in FB" ) )
	{
		Application.OpenURL("fb://profile/447312341955455");
	}

Or if you want to open in safari if the facebook app is not installed and the facebook app if it is installed then the following will work, it appears that iOS captures the facebook.com and directs it to the app if installed automatically:

	if (GUILayout.Button( "Open Tactile Fusion Page in safari" ) )
	{
		Application.OpenURL("http://www.facebook.com/447312341955455");
	}

I’ve done this from a web application. It’s an app that’s registered in FB and uses FB’s graph to have them like posts and comments from the user’s perspective. The only piece of your equation that I’m not 100% on is prime31, however, after reading the documentation, it seems straightforward. My only question I have is what is the user of your application actually ‘Liking’ when the button is clicked?

There’s another excellent plugin for using Facebook with Unity worth checking out:
