IOS Storyboard How to access controls and add event handlers, and bind data to controls added to the storyboard

I used to create a UI through code. But now I need to use the storyboard. I am confused about how to add event handlers to controls added to the storyboard, and how to dynamically associate data with controls added to the storyboard. Example scenario: A UIView is added to the storyboard and two UITableViews, and a button is added above it. I want to add an event handler to a button and bind data to table views. How should I do it. If I subclass UIView added to the storyboard, I will have access to the controls (button, two types of tables) added on top of the view, or how else should I do it ?. Please, help!
