The FBDialog's show method is asynchronous, meaning it returns before it completes whatever it is doing (in this case displaying a window).

You need to implement the delegate methods for responding to facebook dialog messages.

In the delegate methods you can outline the flow of your application.

Currently, your code show's the login dialog window, which returns instantly, and then proceeds on to show another dialog. You should only show the second dialog after the user has logged in, which you can determing using the FBSession delegate methods.
