create iOS app using Promotion

The Goal

Create an iOS app as quickly as we can.

Project Setup

Create a new app

promotion new membershipapp

run tests automatically

gem install when-files-change
when-files-change "clear && bundle exec rake spec"

write test cases

The Promotion TDD framework will instantiate @controller and add a test @app by tests method, we need to call the Promotion::Screen.new and want to use screen instead of controller:

#home_screen_spec.rb

describe HomeScreen do
  tests HomeScreen

  def controller
    @controller ||= HomeScreen.new
  end
  alias :screen :controller

  it "is a TableScreen" do
    screen.should.be.kind_of(PM::TableScreen)
  end
end

create a basic tab screen

The Tabs module is mixed into PM::Screen, to use it, just prepare all the screens, declaring their title and icon, then init screens then call open_tab_bar(*screens) in the main screen

Styling the screen using teacup

Don’t forget to set height and width attributes in the Teacup::Stylesheet, I forget to set it and get nothing to display in the screen.
