ProMotion-menu

ProMotion-menu provides a menu component for the popular RubyMotion gem ProMotion. Utilizing MMDrawerController it allows you to easily have a cool Facebook or Path style slide navigation menu, complete with gestures.

The gem was originally named pro_motion_slide_menu authored by Matt Brewer and continuing development was done by Infinite Red, a web and mobile development company based in Portland, OR and San Francisco, CA. While you're welcome to use it, please note that we rely on the community to maintain it. We are happy to merge pull requests and release new versions but are no longer driving primary development.

Installation

Bundler

Add the following to your project's Gemfile to work with bundler.

gem 'ProMotion-menu'

Install with bundler:

bundle install

Install pods:

rake pod:install

If you're encountering errors, try cleaning before installing pods:

rake clean:all

Dependenices

This depends on motion-cocoapods and ProMotion.

Rakefile

As of motion-cocoapods v1.3.7, you no longer have to include a pods setup block in your project Rakefile, we can do that for you in the gem.

Creating and Configuring a Menu

To create a menu in your application, you need to start in your AppDelegate:

class AppDelegate < PM::Delegate

  def on_load(app, options)

    # Open the menu with your center view (initially shown) and navigation view(s) (initially hidden)
    open_menu MyGreatAppScreen.new(nav_bar: true), left: NavigationScreen

    # You can get to the instance of the menu at any time if you need to
    self.menu.controller(:left).class.name
    # => NavigationScreen

  end

end

Alternate Approach

If you prefer to keep your menu encapsulated you can create a menu drawer and do your setup there.

class MenuDrawer < PM::Menu::Drawer

  def setup
    self.center = MyGreatAppScreen.new(nav_bar: true)
    self.left = NavigationScreen
    self.to_show = [:pan_bezel, :pan_nav_bar]
    self.transition_animation = :swinging_door
    self.max_left_width = 250
    self.shadow = false
  end

end

class AppDelegate < PM::Delegate

  def on_load(app, options)
    @menu = open MenuDrawer
  end

  def show_menu
    @menu.show :left
  end

end

Gesture Recognition

By default you can show the menu by panning within 20 pts of the bezel and hide it by panning or tapping the center view. It's possible to override the default behavior:

# In AppDelegate
open_menu BodyScreen, right: MenuScreen, to_show: :pan_nav_bar, to_hide: [:pan_nav_bar, :tap_nav_bar]

# From elsewhere in your app
app_delegate.menu.to_show = :pan_center

# The following gestures are provided:

  # For to_show:
  :pan_nav_bar  # Pan anywhere on the navigation bar
  :pan_content  # Pan anywhere on the center view
  :pan_center   # Alias of above
  :pan_bezel    # Pan anywhere within 20 pts of the bezel
  :all          # All of the above
  :none         # No gesture recognition

  # For to_hide:
  :pan_nav_bar   # Pan anywhere on the navigation bar
  :pan_content   # Pan anywhere on the center view
  :pan_center    # Alias of above
  :pan_bezel     # Pan anywhere within the bezel of the center view
  :tap_nav_bar   # Tap the navigation bar
  :tap_content   # Tap the center view
  :tap_center    # Alias of above
  :pan_menu      # Pan anywhere on the drawer view
  :all           # All of the above
  :none          # No gesture recognition

Transition Animation

Changing the transition animation is easy:

app_delegate.menu.transition_animation = :swinging_door

# The following transition animation options are available:

  :slide              # Default. Equivalent to :parallax_1 and similar to the menu
                      # in Spotify's app.

  :slide_and_scale    # A slide and scale visual effect similar to Mailbox.app.
                      # Scales from 90% to 100%, translates x 50px, and sets alpha
                      # from 0.0 to 1.0.

  :swinging_door      # A swinging door effect

  :parallax_n                   # A parallax effect where n is a parallax factor.
  :parallax                     # Equiavlent of :parallax_3
  :parallax_1                   # Equivalent of :slide
  :"parallax_#{Float::MAX}"     # Equivalent of no animation at all.

Toggling the Menu Drawer Current Screen

To make the menu drawer present the menu from anywhere in your app:

# Show the menu
app_delegate.menu.show(:left)

# Equivalent to
app_delegate.menu.openDrawerSide MMDrawerSideLeft, animated: true, completion: ->(c) { true }

# Hide the menu
app_delegate.menu.hide

# Equivalent to
app_delegate.menu.closeDrawerAnimated animated: true, completion: ->(c) { true }

# Actually toggle the menu between open/closed states
app_delegate.menu.toggle(:left)
app_delegate.menu.toggle_left

# Equivalent to
app_delegate.menu.toggleDrawerSide MMDrawerSideLeft, animated: true, completion: ->(c) { true }

# You can also adjust the Menu Drawer width
app_delegate.menu.max_left_width = 250

Setting up the Menu

You can use any UIViewController subclass you want as the menu controller, but the easiest way to provide this would be to subclass ProMotion::TableScreen like below:

class NavigationScreen < ProMotion::TableScreen

  def table_data
    [{
      title: nil,
      cells: [{
        title: 'OVERWRITE THIS METHOD',
        action: :swap_center_controller,
        arguments: HomeScreen
      }]
    }]
  end

  def swap_center_controller(screen_class)
    # Just use screen_class if you don't need a navigation bar
    app_delegate.menu.center_controller = screen_class
  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.

If you 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.

A very minimal ProMotion-menu sample is available for reference.
