- Each FBAppAction instance will have a unique ID
- This object is passed into an FBAppActionCompletionHandler for context

sourceApplication | The sourceApplication as passed to [UIApplicationDelegate application:openURL:sourceApplication:annotation:]. |
session | If this url is being sent back to this app as part of SSO authorization flow, then pass in the session that was being opened. A nil value defaults to FBSession.activeSession |

- (BOOL) isEqualToAppAction:(FBAppAction *)appAction;FBAppAction.hFBAppActionCompletionHandlerA block that is passed to performAction to register for a callback with the results of that action
typedef void (^FBAppActionCompletionHandler)( FBAppAction *action, NSDictionary *results, NSError *error); Pass a block of this type when calling performAction. This will be called once the action completes. The call occurs on the UI thread.
