ProMotion is maintained by Infinite Red, a web and mobile development company based in Portland, OR and San Francisco, CA.

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.

# app/app_delegate.rb
class AppDelegate < PM::Delegate
  status_bar true, animation: :fade

  def on_load(app, options)
    open RootScreen
  end
end

# app/screens/root_screen.rb
class RootScreen < PM::Screen
  title "Root Screen"
  nav_bar true

  def on_load
    set_nav_bar_button :right, title: "Help", action: :open_help_screen
  end

  def open_help_screen
    open HelpScreen
  end
end

# app/screens/help_screen.rb
class HelpScreen < PM::TableScreen
  title "Table Screen"

  def table_data
    [{
      title: "Help",
      cells: [
        { title: "About this app", action: :tapped_about },
        { title: "Log out", action: :log_out }
      ]
    }]
  end

  def tapped_about(args={})
    open AboutScreen
  end

  def log_out
    # Log out!
  end
end
