Simply click on View Controller in the Document Outline and press the delete key on your keyboard.ĭrag a tab bar controller from the Object Library into the canvas. To add the tabbed interface, start by opening Main.storyboard and deleting the only scene there. The app you’re about to build has a tabbed interface with two scenes. Now, it’s time to start building the Ratings app. The Document Outline will be one of your main navigation points to select the elements of the storyboard. In this tutorial, you’ll use the name “scene” to refer to the view controller inside your storyboard. View controllers are called scenes on the storyboard. The Document Outline shows all the items you have inside the open storyboard file, as well as any view controller and any of the controls it includes. Before you start on the app, there’s one more item on the screen you should know about: The Document Outline. You’ll rely heavily on the Object Library to design your storyboards. You can change their position or remove them later. To design the layout in the storyboard editor, drag controls from the Object Library and drop them into your scene in the position you want. You’ll then be able to select from the full range of supported device sizes, from the iPad Pro (12.9-inch) to the iPhone 4s (3.5-inch), in both portrait and landscape orientations. To change the scene size to another device, click the button at the bottom-left of the storyboard. They allow you to make flexible user interfaces that can resize easily, which is useful for supporting various sizes of iPhones and iPads. Xcode enables Auto Layout and Size Classes by default for storyboards. You’ll notice the default scene size is for a 4.7-inch screen. You’ll learn about this in more detail later. The arrow pointing to the view controller from the left indicates it’s the initial view controller for this storyboard. Here, you see a single view controller containing an empty view. Open Main.storyboard in the Project navigator to view it in the Interface Builder editor: Find Device Orientation and, since this is a portrait-only app, uncheck the Landscape Left and Landscape Right options. Under Deployment Info in the General project settings, uncheck iPad. swift files in this tutorial, so don’t worry about them. You don’t need to change anything in the.
