Ruby script which adds documentation for all dependencies from a Podfile to Dash. It's rather hacky and was only tested on Sea Lion, so use at your own risk.

dashpod.rb

#!/usr/bin/env ruby

require 'rubygems'

require 'cocoapods-core'
require 'json'
require 'mechanize'
require 'rest-client'

docs = JSON.parse(RestClient.get('http://cocoadocs.org/documents.jsonp')[12..-22])
podfile = Pod::Podfile.from_file('Podfile')

for dep in podfile.dependencies().map { |d| d.name  }
  for doc in docs
		if doc['name'] == dep
			agent = Mechanize.new
			page = agent.get(doc['doc_url'])
			dash_url = page.links_with(:text => 'Dash').first.href

			system('open', dash_url)
		end
	end
end
