In this chapter, we covered the basic settings that Apple and Xamarin provide for developing iOS applications. This includes the Info.plist file and project options in Xamarin Studio. We covered UINavigationController, the basic building block for navigation in iOS applications, and implemented a login screen complete with username and password fields. Next, we covered iOS segues and the UITableView class. We implemented the friends list screen using UITableView, and the messages list screen, also using UITableView. Lastly, we added a custom UI functionality: a custom toolbar floating at the bottom of the messages list.

Upon completing this chapter, you will have a partially functional iOS version of XamChat. You will have a deeper understanding of the iOS platform and tools, and fairly good knowledge to apply to building your own iOS applications. Take it upon yourself to implement the remaining screens that we did not cover in the chapter. If you get lost, feel free to review the full sample application included with this book.
