Getting

GettingStarted

を参考にHelloWorldをする．

まずはコマンドの確認．

$which motion
/usr/bin/motion

iOS SDKが入っている必要がありますが，僕の環境には既にXCodeが入っているので飛ばします．

RubyMotionのアップデートが無いか確認．

$motion -v
1.2
$sudo motion update
Password:
Connecting to the server….
Software is up to date
$ motion -v
1.2

最新でした．

Hello Worldします．

$motion create Hello
    Create Hello
    Create Hello/.gitignore
    Create Hello/Rakefile
    Create Hello/app
    Create Hello/app/app_delegate.rb
    Create Hello/resources
    Create Hello/spec
    Create Hello/spec/main_spec.rb
$cd Hello
$rake
===============================================================================
It appears that you have a version of Xcode installed in /Applications that has
not been set as the default version. It is possible that RubyMotion may be
using old versions of certain tools which could eventually cause issues.

To fix this problem, you can type the following command in the terminal:
    $ sudo xcode-select -switch /Applications/Xcode.app/Contents/Developer
===============================================================================
     Build ./build/iPhoneSimulator-5.0-Development
   Compile ./app/app_delegate.rb
    Create ./build/iPhoneSimulator-5.0-Development/Hello.app
      Link ./build/iPhoneSimulator-5.0-Development/Hello.app/Hello
    Create ./build/iPhoneSimulator-5.0-Development/Hello.app/Info.plist
    Create ./build/iPhoneSimulator-5.0-Development/Hello.app/PkgInfo
    Create ./build/iPhoneSimulator-5.0-Development/Hello.dSYM
  Simulate ./build/iPhoneSimulator-5.0-Development/Hello.app
2012-05-09 03:33:40.258 Hello[33099:f803] Applications are expected to have a root view controller at the end of application launch
(main)>>   

で，シミュレータが起動しますが，何も書いていないので空です．

./app/app_delegate.rb

を編集します．

class AppDelegate
  def application(application, didFinishLaunchingWithOptions:launchOptions)
    alert = UIAlertView.alloc.initWithTitle(
        "Title",
        message:"message", 
        delegate:nil,
        cancelButtonTitle:nil,
        otherButtonTitles:"OK")
    alert.message = "Hello World"
    alert.show
    true
  end
end

ビルドし直します．

$rake

シミュレータが起動して，Alertが表示されます．
