20. FooViewController FooView FooController index show new edit
21. ViewControllers are structured in a stack bar_controller = BarViewController.alloc.init navigationController.pushViewController(bar_controller, animated: true) # do something.. navigationController.popViewController(bar_controller, animated: true)
23. > label = adjust(53) => UILabel(#1e8b9ce0, [[210.0, 5.0], [30.0, 25.0]], text: nil), child of MenuItemView(#1e8b6200) stylename: :news_count ! > label.frame.origin.x += 10 => 220.0 ! > right 5 => [[225.0, 5.0], [30.0, 25.0]] # => [x, y], [width, height] ! > label.text = "Hello World" => "Hello World"
