The original tutorial was written by Matthijs Hollemans. Storyboards are an exciting feature first introduced in iOS 5 that save time building user interfaces for your apps. Storyboards allow you to prototype and design multiple view controller views within one file. Open Xcode and create a new project. Use the Single View Application template as the starting point. The new project consists of three files, AppDelegate, ios 7 xcode tutorial. Since this is a portrait-only app, uncheck the Landscape Left and Landscape Right options.

Open Main. A scene represents a view controller in the storyboard. Here you see a single view controller containing an empty view. Designing a layout in the storyboard editor is done by dragging controls from the Object Library see bottom-right corner into your view controller. Xcode enables Auto Layout and Size Classes by default for storyboards. Auto Layout and Size Classes allow you to make flexible user interfaces that can easily resize, which is useful for supporting the various sizes of iPhones and iPads.

To change the scene size to another device, click the button at the bottom left of the storyboard. Xcode will automatically re-size existing and new scenes added to the storyboard for the currently-selected device size. To get a feel for how the storyboard editor works, drag some controls from the Object Library into the blank view controller:, ios 7 xcode tutorial. The storyboard shows the contents of all your scenes. The Dock shows the top-level objects in the scene.

It can potentially have other top-level objects as well. The Dock is convenient for making connections to outlets and actions. If you need to connect something to the scene, you can simply drag to its icon in the Dock. Build and run the app, it should look exactly like what you designed in the editor yours may look different than the screenshot below :.

The single view controller you defined was set as ios 7 xcode tutorial Initial View Controller — but how did the app load it? Open AppDelegate. The UIApplicationMain attribute at the top of the file designates the AppDelegate class as the entry point for the module. All the methods are practically empty, ios 7 xcode tutorial. Open Info. This can be done by clicking on View Controller in the Document Outline and pressing the delete key.

You can zoom in and out by double-clicking the canvas, or set the zoom scale by ctrl-clicking the canvas and selecting the zoom level. The new Tab Bar Controller comes pre-configured with ios 7 xcode tutorial additional view controllers — one for each tab. UITabBarController is a so-called container view controller because it contains one or more other view controllers.

The container Relationship is represented by the arrows between the Tab Bar Controller and the view controllers it contains. An embed Relationship in particular is signified by the icon seen below in the middle of the arrow body.

This allows you to see something happen when you switch between the tabs. Ratings[] Failed to instantiate the default view controller for UIMainStoryboardFile 'Main' - perhaps the designated entry point is not set? Build and run the app. Now you can see a tab bar and can switch between the two view controllers:.

Xcode comes with a template for building a tabbed app called the Tabbed Application template. Click on the first view controller in the Document Outline to select it, ios 7 xcode tutorial, then delete it. Drag a new Table View Controller into the canvas where the previous scene used to be:.

Next, you want to place the Table View Controller inside a navigation controller. First, select the Table View Controller. This adds another controller to the canvas:. You could have dragged in a Navigation Controller from the Object Library and embedded the table view, but this Embed In command is a nice time saver for a common action. Since the Navigation Controller is also a container view controller just like the Tab Bar Controllerit has a relationship arrow pointing to the Table View Ios 7 xcode tutorial. You can also see these relationships in the Document Outline :.

Notice embedding the Table View Controller gave it a navigation bar. When you let go, a small popup menu appears, ios 7 xcode tutorial. Choose the Relationship Segue — view controllers option:. This creates a new relationship arrow between the two scenes.

This is also an embed Relationship as you saw with the other controllers contained by the Tab Bar Controller. The Tab Bar Controller has two embed relationships, one for each tab. For this app, you want this new scene to be the first tab, so drag the tabs around to change their order:, ios 7 xcode tutorial. Build and run the app to try it out. The first tab now contains a table view inside a navigation controller. Before you put some actual functionality into this app, you need to clean up the storyboard a little.

Next, rename the Tab Bar Item for the second tab to Gestures the same way you did above, ios 7 xcode tutorial. A well-designed app should also put icons on these tabs. The resources for this tutorial contains a subfolder named Images.

Drag that folder into the Assets. A view controller embedded inside a Navigation Controller has a Navigation Item used to configure the navigation bar. Now marvel at your pretty tab bar, created without writing a single line of code! Prototype cells allow you to easily design a custom layout for your table view cells directly within the storyboard editor.

The Table View Controller comes with a blank prototype cell. Click the cell to select it and in the Attributes inspector set the Style option to Subtitle. This immediately changes the appearance ios 7 xcode tutorial the cell to include two labels. Subtitle style. All prototype cells must have a reuse identifier so you can refer to them in code.

Build and run the app, nothing has changed. Add a new file to the project. Uncheck Also create XIB file. Choose the Swift language and hit Next followed by Create. This is an essential step for hooking up a ios 7 xcode tutorial from the storyboard with your custom view controller subclass. Now when you run the app the table view controller from the storyboard is an instance of the PlayersViewController class.

Next, create a new file using the Swift File template named SampleData. Replace the contents of SampleData. Next, open PlayersViewController, ios 7 xcode tutorial.

You could have set up the sample data in PlayersViewController when defining the players variable. Still in PlayersViewController. If not, it will automatically allocate a prototype cell and return it to you. All you need to do is supply the re-use identifier you set on the prototype cell in the storyboard editor — in this case PlayerCell. The default labels now disappear. First make the cell a little taller. Either ios 7 xcode tutorial the Row Height value in the Size inspector after checking Custom or drag the handle at the bottom of the cell.

Make the cell 60 points high. Drag two Label objects from the Objects Library into the cell and place them roughly where the standard labels were previously. Just play with the font and colors in the Attributes Inspector and pick something you like. Set the text of the top label to Name and the bottom label to Game. Drag an Image View into the cell and place it on the right, next to the disclosure indicator.

In the Size Inspector, make it 81 points wide and 35 points high. Set its Content Mode to Center under View in the Attributes inspector so whatever image you put into this view is not stretched. Xcode will create a new horizontal stack view containing these two controls. Select this new horizontal stack view, and in the Attributes Inspectorchange the Alignment to Center and the Distribution to Equal Spacing.

Now for some simple auto layout for this control. At the bottom right of the storyboard, ios 7 xcode tutorial, click the Pin icon:. Change the top constraints to Top: 0Right: 20Bottom: 0 and Left: Make sure the four red pointers to the values are highlighted as in the picture.

Click Add 4 Constraints at the bottom of the popover window. If your stack view has orange constraints, it is misplaced.
