title: How to execute some code after a segue is done?
body: <p>Is it possible in iOS 6 to know when a <code>UIStoryboardSegue</code> has finished its transition? Like when i add a <code>UIStoryboardSegue</code> from  <code>UIButton</code> to push another <code>UIViewController</code> on the navigationcontroler, i want to to something right after the push-transition is finished.</p>
