Note: Have a brief look at our Auto Layout in Interface Builder tutorial. You’ll only be working in ViewController.swift and AvatarView.swift.

These are separated out because you won’t be changing any of this code. The setup methods are defined in ViewControllerExtension.swift. Open ViewController.swift, there’s only one method – viewDidLoad() – which calls methods to set up the three views. The three views are properly positioned using the view’s frame property.īut rotate the device ( Cmd + left or right arrow), and the views don’t expand correctly to fill the landscape width: You can swipe the text view left or right to move to the next and previous chapters.

Note: Use the iPhone 6s Plus or 7 Plus simulator for testing unless told otherwise. Getting Startedĭownload the Wonderland starter app and open it up in Xcode. In addition, if you learn how Auto Layout works in code, it’s easier to apply it in Interface Builder, which can become difficult to follow when you’re laying out various size class combinations.

It’s easier to reuse code rather than copy Interface Builder views across several apps. For example, Wonderland contains an avatar profile view that you can use across several apps. Using code to create all the views and constraints, you’ll lay out the app differently using Compact and Regular size classes.Īlthough the team advocates using storyboards whenever possible, sometimes it’s better to use code to create your views. Here’s what the app will look like when you’re finished: You’ll be creating an app called Wonderland, a simple Alice in Wonderland story app.

In short, you’ll learn how to stay afloat with Auto Layout. Creating constraints in code will lead to a greater understanding of Auto Layout constraint relationships, and even make it easier for you create Auto Layout driven views in Interface Builder. Never fear! In this Auto Layout tutorial instead of using Interface Builder and storyboards, you’ll create all your constraints in code using layout anchors, a new API delivered as part of iOS 9. When you are done with this tutorial, you will have the necessary knowledge and tools to keep the content from appearing under the status bar.Update 9/26/16: This tutorial has been updated for Xcode 8 and Swift 3.ĭo you find Auto Layout challenging? Do you find yourself making and unmaking constraints over and over in a never-ending attempt to find the seemingly random correct layout? Do you find it daunting when you have to modify Auto Layout constraints in code? This Q&A takes you through a process showing how to properly place a UIToolbar using Auto Layout and Interface Builder.

Figure 1 Full screen view controller underneath the status bar Figure 2 Shows the view below the status bar, similar to the pre-iOS 7 behavior.Īpplications that use an opaque UINavigationController or UITabBarController automatically keep their content below the status bar.Īny view that needs to be anchored to the top and just below the status bar (i.e., UIToolbar, UIButton, etc.) requires additional work for proper placement. This means they will cover the entire screen including the area underneath the status bar. How do I prevent the status bar from covering my views in iOS 7?Ī: You need to use Auto Layout and apply a vertical spacing anchored to the "Top Layout Guide" of your view controller.īeginning with iOS 7 view controllers are displayed full screen, by default, as shown in Figure 1.
