SimpleView

A DSL for UIKit for RubyMotion.

Demo app: Currency

Installation

Add the gem to your Gemfile

gem 'simple-view', :git => 'https://github.com/seanho/SimpleView.git'

Then bundle install

Require SimpleView in Rakefile

$:.unshift("/Library/RubyMotion/lib")
require 'motion/project'
require 'simple-view'

Motion::Project::App.setup do |app|
  ...
end

Usage

def viewDidLoad
  UI::Layouts.setup(view) do
    label width: 200, height: 20, text: "Choose your lucky word", color: "#eee"
    image_view top: 50, left: 50, right: 50, image: "sample.jpg"
    toolbar anchors: [:bottom]
  end
end

Everything inside setup block will be added to the view automatically.

Hash parameters works only on KVC-compliant properties. To configure view object in more detail, use a block

def viewDidLoad
  UI::Layouts.setup(view) do
    button do
      @view.setTitle("Submit" forState: UIControlStateNormal)
    end
  end
end

Custom view support

SimpleView works not only with UIKit, custom or 3rd party created views and controls can also be used

UI::Layouts.setup(view) do
  add CustomViewClass, name: "custom_view"...
end

Style Template

Experimental. Might change in future.

Define a style and apply to multiple views with ease.

class AppDelegate
  def application(application, didFinishLaunchingWithOptions:launchOptions)
    UI::Styles.define :tag_label,
      font: "italic 13",
      text_color: "#999"
  end
end
  
class ViewController
  def viewDidLoad
    UI::Layouts.setup(view, controller: self) do
      label styles: :tag_label, text: "Left", anchors: [:left]
      label styles: :tag_label, text: "Right", anchors: [:right]
    end
  end
end

View anchoring

UI::Layouts.setup(view) do
  toolbar bottom: 10, left: 10, right: 10, anchors: [:bottom]
end

Passing in locals

Hash parameters will automatically turns into instance variable within the block

def viewDidLoad
  UI::Layouts.setup(view, controller: self) do
    table_view delegate: @controller, dataSource: @controller
  end
end

View tagging with string

No need to declare ivar, no need to use integer tag, just name your view and access it by the name.

def viewDidLoad
  UI::Layouts.setup(view) do
    label name: "price_label" # give a name to the label
  end
end

def someOtherMethod
  view.subview("price_label") # get the label
end
