ProMotion

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.

Watch the September Motion Meetup where Gant Laborde interviews Jamon Holmgren about ProMotion!

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

What's New?

Version 1.0

• New Screen PM::MapScreen
• New Screen PM::WebScreen
• Added indexable as a PM::TableScreen feature
• Added PM::SplitViewController and the ability to open a screen in_detail: or in_master:. More info here.
• Added PM::TabBarController and PM::Tabs and refactored the open_tab_bar code
• IMPORTANT: Changed on_load to fire more consistently. You are now encouraged to put your view setup code in here rather than will_appear.
• Many methods that used to require long UIKit constants now take short :symbols. Check documentation.
• Simpler PM::Delegate code, added will_load(app, options) and others. See the documentation.
• Added a few keys and improvements to table_data
• Removed PM::SectionedTableScreen (PM::TableScreen is already a sectioned table)
• Removed any last UIKit monkeypatching. Everything is a subclass now. ProMotion is probably the least invasive RubyMotion gem in common use.
• Push Notification updates
• Renamed PM::ViewHelper to PM::Styling and added some common helpers
• Added will_present, on_present, will_dismiss, on_dismiss to screens
• Major internal refactors everywhere
• Lots of new unit & functional tests
• Removed deprecations, cleaned up a lot of code
• Huge improvements to the wiki

5. Contribute!

Submitting a Pull Request

1. Fork the project
2. Create a feature branch
3. Code
4. Update or create new specs ** NOTE: your PR is far more likely to be merged if you include comprehensive tests! **
5. Make sure tests are passing by running rake spec (you can run functional and unit specs separately with rake spec:functional and rake spec:unit)
6. Submit pull request to edge (for new features) or master (for bugfixes)
7. Make a million little nitpicky changes that @jamonholmgren wants
8. Merged, then fame, adoration, kudos everywhere
