initWithNibName method in storyboard

I am following Facebook's tutorial to post to a user's wall: http://developers.facebook.com/docs/howtos/publish-to-feed-ios-sdk/ and although it is made with a .xib project in mind, I have been able to do everything just fine with my storyboard project so far. However, I have come to the point where I need to put some code into the initWithNibName:bundle: method, but I cannot do this because I am using storyboard. And, since it's hard to tell when exactly the method would be called, I can't just write a method named initWithNibName:bundle: and call it from some other method. If anyone has any idea of how to solve my issue, please say so. Thanks.
