Overview of this book

RubyMotion is a revolutionary toolchain for iOS app development. With RubyMotion, you can quickly develop and test native iOS apps for the iPhone and iPad, combining the expressiveness and simplicity of Ruby with the power of the iOS SDK. "RubyMotion iOS Development Essentials" is a hands-on guide for developing iOS apps using RubyMotion. With RubyMotion, you can eliminate the complexity and confusion associated with the development of iOS applications using Objective-C. We'll begin from scratch. Starting by installing RubyMotion, we'll build ourselves up to developing an app that uses the various device capabilities iOS has to offer. What's more, we'll even learn how to launch your app on the App Store! We'll also learn to use iOS SDK classes to create application views. Discover how to use the camera, geolocation, gestures, and other device capabilities to create engaging, interactive apps. We'll develop stunning user interfaces faster with the XCode interface builder and make web apps by using WebView. We'll then augment applications with RubyMotion gems, doing more by writing less code and learn how to write test cases for RubyMotion projects. Finally, we'll understand the app submission process to push your app to Apple's App Store With "RubyMotion iOS Development Essentials", we will learn how to create iOS apps with ease. At the end of each chapter we will have a tangible and running app, which utilizes the concepts we have learnt in that chapter.

Model-View-Controller (MVC)

Model-View-Controller (MVC) is a design principle that separates the representation of information from the user's interaction. The main purpose of MVC is to make the code more modular and reusable, which increases the product quality.

Most of the popular commercial and noncommercial application frameworks are created to enforce the MVC design pattern. However, RubyMotion does not force you to use MVC style, but this way of programming is central to a good design for application development. If we make use of MVC while developing our application, it will be beneficial for us later on, as we will be able to add new features more easily.


Apple's Cocoa framework is also based on Model-View-Controller.

As the name implies, the application is divided into three distinct parts: model, view, and controller, where model encapsulates application data, view displays and allows editing the data, and controller is the place where logic of the interaction between the two...
