ProMotion is a RubyMotion gem that makes iOS development more like Ruby and less like Objective-C. It introduces a clean, Ruby-style syntax for building screens that is easy to learn and remember and abstracts a ton of boilerplate UIViewController, UINavigationController, and other iOS code into a simple, Ruby-like DSL.

class AppDelegate < PM::Delegate
  def on_load(app, options)
    open RootScreen.new(nav_bar: true)
  end
end

class RootScreen < PM::Screen
  title "Root Screen"
  
  def push_new_screen
    open NewScreen
  end
end

class NewScreen < PM::TableScreen
  title "Table Screen"
  
  def table_data
    [{
      cells: [
        { title: "About this app", action: :tapped_about },
        { title: "Log out", action: :log_out }
      ]
    }]
  end
end
