Add button in container

[PatrickRguez]

HI There!

I´m trying to include a button inside of FirstViewController view. I add the button in the storyboard but when I create the action to print anything, it doesn´t work. I only can use elements of ViewController and I can´t use anything of this view. Buttons, scrolls... How can I send the delegate? I want to use FirstViewController, not remain with ViewController

Thank you very much
