RubyMotionのレイアウト制御ライブラリMotion-layoutsのサンプルを使って遊んでみた。

gistfile1.rb

class AppDelegate
  def application(application, didFinishLaunchingWithOptions:launchOptions)
    @window = UIWindow.alloc.initWithFrame(UIScreen.mainScreen.applicationFrame)
    @window.rootViewController = ExamMotionLayoutViewController.alloc.init
    @window.rootViewController.wantsFullScreenLayout = true
    @window.makeKeyAndVisible
    return true
  end
end

class ExamMotionLayoutView < UIView
end

class ExamMotionLayoutViewLayout
  include Layouts::Base

  def self.template
    UIToolbar {
      anchor 'top'
      height 50
      resize :top, :right, :left, :width
      items [
        ['Cancel', 'touchesCancel'],
        [:flexible_space],
        ['Show', 'touchesShow']
      ]
    }
    
    UITextField {
      id 'nameTextField'
      delegate @controller
      top 90
      width 85.percent
      align 'center'
      text_color '222222'
      background_color 'FFFFFF'
      border_style 'rounded'
      resize :top, :right, :left, :width
      placeholder 'Input your name'
    }
  end
end

class ExamMotionLayoutViewController < UIViewController
  def loadView
    self.view = ExamMotionLayoutView.alloc.init
    self.view.backgroundColor = UIColor.whiteColor
  end
  
  def viewWillAppear(animated)
    super
    view.fromLayout(ExamMotionLayoutViewLayout, self)
  end
  
  def touchesCancel
    alert = UIAlertView.new
    alert.message = "Cancelled"
    alert.addButtonWithTitle("閉じる")
    alert.show
  end
  
  def touchesShow
    alert = UIAlertView.new
    alert.message = @nameTextField.text
    alert.addButtonWithTitle("閉じる")
    alert.show
  end
end
