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.

CocoaPods – managing Objective-C libraries

CocoaPods is the best way to manage library dependencies in Objective-C projects. CocoaPods was originally designed to be integrated in Objective-C Xcode projects, but it can readily be used in RubyMotion projects using the motion-cocoapods gem.

Installing CocoaPods with RubyMotion

Perform the following steps to install CocoaPods with RubyMotion:

  1. Install CocoaPods.

       $sudo gem install cocoapods
  2. Set up CocoaPods.

       $pod setup
  3. Install motion-cocoapods to work with RubyMotion.

    $sudo gem install motion-cocoapods

Now we are all set to use CocoaPods in our RubyMotion project. Add the following code in the Rakefile:

Motion::Project::App.setup do |app|
  app.pods do
    dependency 'Reachability'

So, next time when you build your code, it will automatically download the library for you. Then you can use the Objective-C CocoaPods in your project.
