rubymotion interface builder support (yes, with outlets)

Add this line to your application's Gemfile:

gem 'ib'

And then execute:

$ bundle

Or install it yourself as:

$ gem install ib

In your Rake file:

$:.unshift("/Library/RubyMotion/lib")  
require 'motion/project'  

# if you use bundler
require 'bundler' 
Bundler.require

# if you are not using bundler
require 'rubygems'
require 'ib'

Motion::Project::App.setup do |app|
  # ...
end

Generate controller with folllowing command:

ib c Hello UIViewController \
  --outlets scroller:UIScrollView btn_hello:UIButton \
  --actions say_hello \
  --accessors data_source

The generated file:

class HelloController < UIViewController
  extend IB

  ## define accessors
  attr_accessor :data_source, :scroller, :htn_hello

  ## define ib outlets
  ib_outlet :scroller, UIScrollView
  ib_outlet :btn_hello, UIButton

  ## define actions
  def say_hello(sender)
    # TODO Implement action here
  end

  ## define ib action 
  ib_action :say_hello

end
