RubyMotion iOS Development Essentials

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.

Therefore, to create an application using RubyMotion, we require only two tools; the first is your favorite editor and the second is the terminal. While developing a RubyMotion application, you will be required to familiarize yourself with the command line. Familiarity with the terminal always helps in faster and comfortable development.

Now that we have created our HelloWorld application, let us explore a few commands that we have already used, and remember that RubyMotion uses them considerably. These commands are responsible for inaugurating our RubyMotion projects, motion and rake.

Motion command – one-stopshop

As used previously, the motion command creates our RubyMotion project and also supports various other options. The motion command is similar to the popular framework Ruby on Rails' rails command. Before we go any further, let's fire up our terminal and see what can...
