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. I love hearing from my readers and I appreciate that you’re learning with me.Do 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? If this guide helped you, please let me know by leaving a quick comment below.
