Combining Storyboards with traditional nib-files?

is possible combine storyboards traditional nib-files?

reason i'm asking storyboards not expose appdelegate, , if wish call method in class appdelegate it's excruciatingly painful (exampel: http://www.raywenderlich.com/5138/beginning-storyboards-in-ios-5-part-1).

know it's possible use them both separately in single project, how can make them interact?

thinking nib-file, exposing appdelegate, connect relevant views in storyboard wants call methods from.

dreaming?

 

i've spent considerable amount of time googling issue, , have found no apparent solution, i'm guessing out of question.

how can programmatically, (look @ bottom skip frustrated flailing ):
