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.

Your first application

Let's start with the classic HelloWorld application. As we have discussed in the last chapter, RubyMotion has a terminal-based flow, so let's fire up our terminal and create our very first RubyMotion application.

$motion create HelloWorld
Create HelloWorld
    Create HelloWorld/.gitignore
    Create HelloWorld/Rakefile
    Create HelloWorld/app
    Create HelloWorld/app/app_delegate.rb
    Create HelloWorld/resources
    Create HelloWorld/spec
    Create HelloWorld/spec/main_spec.rb

If you observe closely the output on the terminal screen, you will see that a lot of files and directories have been generated by a single motion command, which automatically creates standard directories, and you will also see the file structure that will quickly bring us onboard with app development, which we can work on later and enhance to make a fully functional application. Moreover, since the structure is common to all the RubyMotion apps, it's easy to understand.
