RubyMotionのAppDelegateに書くべき基本的なViewのテンプレート

ViewControllerのサンプル

main_view_controller.rb

class MainViewController < UIViewController
  def viewDidLoad
    super

    @label = UILabel.new
    @label.frame = [[10, 10], [320, 20]]
    @label.font  = UIFont.boldSystemFontOfSize(16)
    @label.text  = "Hello World"

    view.backgroundColor = UIColor.whiteColor
    view.addSubview(@label)

	# for navigation bar
    navigationItem.title = "Navigation Title"

	# for tab bar
	self.tabBarItem = UITabBarItem.alloc.initWithTitle("Tab1", image: nil, tag: 1)
  end
end

Single View

app_delegate.rb

class AppDelegate
  def application(application, didFinishLaunchingWithOptions:launchOptions)
    @window = UIWindow.alloc.initWithFrame(UIScreen.mainScreen.bounds)
    @window.rootViewController = MainViewController.new
    @window.makeKeyAndVisible
    true
  end
end

Navigation Bar View

app_delegate.rb

class AppDelegate
  def application(application, didFinishLaunchingWithOptions:launchOptions)
    @window = UIWindow.alloc.initWithFrame(UIScreen.mainScreen.bounds)

	nav_controller = UINavigationController.alloc.initWithRootViewController(MainViewController.new)
    @window.rootViewController = nav_controller

    @window.makeKeyAndVisible
    true
  end
end

Tab Bar View

app_delegate.rb

class AppDelegate
  def application(application, didFinishLaunchingWithOptions:launchOptions)
    @window = UIWindow.alloc.initWithFrame(UIScreen.mainScreen.bounds)

    tab1 = MainViewController.new
	# tab2 = OtherViewController.new
    tab_controller = UITabBarController.new
    tab_controller.viewControllers = [tab1]

    @window.rootViewController = tab_controller
    @window.makeKeyAndVisible
    true
  end
end

補足

newはalloc.initと同じ意味

MainViewController.new = MainViewController.alloc.init

tap好きな人用

@window = UIWindow.alloc.initWithFrame(UIScreen.mainScreen.bounds).tap do |window|
  window.rootViewController = MainViewController.new
  window.makeKeyAndVisible
end
