ProMotion

ProMotion was created by me, Jamon Holmgren. While you're welcome to use ProMotion, please note that it's no longer maintained!

(And yes -- I created it long before Apple launched their own ProMotion.)

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

Apps built on ProMotion

Open a pull request! We love adding new ProMotion-built apps.

We have comprehensive documentation with code examples, usage examples, and API reference.

• Watch Jamon Holmgren give a talk about ProMotion at RubyMotion #inspect2014 (video)
• Watch the September 2013 Motion Meetup where Gant Laborde interviews Jamon Holmgren about ProMotion

We're no longer supporting ProMotion and it's mostly retired. If you need help, feel free to file an issue, but I may not see it.
