Xamarin in Action

Chapter 11. Building simple iOS views

This chapter covers

• iOS storyboard resources
• Laying out controls using auto layout and constraints
• Supporting multiple screen sizes using size classes
• Adding images to support multiple screen sizes using asset catalogs
• Creating view controllers
• The view controller lifecycle

In the last two chapters we built the UIs for SquareRt and Countr on Android. In this chapter and the next, we’ll build these view layers on iOS (figure 11.1). We’ll start here by looking at how to build an iOS UI and then build the UI for SquareRt. In the next chapter we’ll look at Countr, and you’ll see some slightly more advanced UI techniques, including using table views to show lists of data, menus, and navigation.
