UNMAINTAINED PROJECT
I stopped developing in RubyMotion long time ago and can no longer maintain the project.

A small gem to create clean wizard-like views

gem install motion-wizard

# or in Gemfile
gem 'motion-wizard'

Your custom wizard view controller will inherit from MotionWizard::WizardViewController.

With the steps class method, you specify which view controllers will describe your wizard.

class Wizard1ViewController < MotionWizard::WizardViewController
  steps Step1ViewController,
        Step2ViewController,
        Step3ViewController,
        Step4ViewController
end

The WizardViewController will create instances of your steps controllers which will then be extended with the MotionWizard::ContentController module. This module gives you the following methods which can be used inside your steps:

• #next(data): Will move to the next step. It will call #finish if there is no following step.
• #previous(data): Will move to the previous step. If already on the first step, this method will do nothing.
• #go_to_step(step_number, data): Will go to the selected step.
• #finish(data): Will call the #when_finished method on the wizard view controller

When moving through steps, you can pass an optional hash parameter with custom data that will get merged into a common wizard hash. You can access this hash inside your steps with the #wizard_data method.

class Step1ViewController
    ...

    def viewWillAppear(animated)
      super
      @button.on(:touch){ self.next(step_1_text: "Awesome!") }
    end

    ...
end

Your wizard view controller class can define a #when_finished method that will get called when any of the steps view controller call #finish or #next when already on the last step. Within this method you have also access to wizard_data.

class Wizard1ViewController < MotionWizard::WizardViewController
    def when_finished
        NSLog "You can access your data here #{wizard_data}"
    end
end

By default, index views will be instances of MotionWizard::IndexItem. This view has a label_wrapper (UIView) subview, which has a label (UILabel) subview.

It also defines two methods when_selected and when_unselected that allow to subscribe a block to be called whenever the current step changes.

You can customize the default index view appearance and behaviour by defining the set_up_index_item_at(index_item, index) method inside your WizardViewController subclass (see sample Nr 1).

class Wizard1ViewController < MotionWizard::WizardViewController
  def setup_index_item_at(index_item, index)
    layout(index_item, :index_item)
    index_item.label.text = "ABCD"[index]
  end
end

If you would rather use a custom index item class instead of the default one, you can register it using the index_item_view_class class method inside your WizardViewController subclass definition.

Your custom class can define the methods #select and #unselect to be called whenever the wizard changes the current step.
