    Any view can present a modal view

    Up until now, we’ve presented new views using our Navigation Controller. Things are a little different for modal views: any UIViewController can show a modal view, then dismiss it when necessary. To display a modal view on top of the current view, simply send the current view the presentModalView Controller:animated: message. Since our RootViewController is the View Controller that needs to show the modal view, we can just send this message to ourselves, using self, like this:

    Sharpen your pencil

    Update the RootViewController.m file to display our AddDrinkViewController when the + button is tapped.

    Import the AddDrinkViewController.h so the RootViewController knows what class you’re talking about.
