Chapter 2. Instant Gratification – Your First Application

"Dream the impossible, seek the unknown, and achieve greatness."


Now that we are all charged up about RubyMotion and have our system set up, let's create a simple RubyMotion application. We will try and keep it simple, but sometimes you may feel disconnected by monotonously typing the code. Although, going along is enough for now. Remember that mimicry is a powerful form of learning; that's how we have learned most of our skills, such as talking, reading, writing, and that is how you will learn to program with RubyMotion. We promise you that by the end of this book, you will have sufficient knowledge of RubyMotion to create an iOS application and make it live on the App Store. In this chapter we will cover the following topics:

  • Creating your first RubyMotion application

  • Understanding the folder structure

  • Exploring the command line

  • Configuring your application

  • REPL – the interactive console

  • The debugger
