ProMotion

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

iPhone Apps, Ruby-style

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

Help

ProMotion is not only an easy DSL to get started. The community is very helpful and welcoming to new RubyMotion developers. We don't mind newbie questions.

The quickest way to get help is to join the Motioneers Slack Group. If you still need help, feel free to open an issue on GitHub. If we don't respond within a day, tweet us a link to the issue -- sometimes we get busy.
