RubyMotion HelloWorld〜実機転送まで…行きたかったけどiOS4に対応してなかったので断念

真っ黒画面

Welcome to RubyMotion
をそのままやってみる。

$ 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
     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
2012-05-07 22:03:37.656 Hello[7703:f803] Applications are expected to have a root view controller at the end of application launch
(main)>>

$ 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

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

2012-05-07 22:03:37.656 Hello[7703:f803] Applications are expected to have a root view controller at the end of application launch

(main)>>

こんな感じで真っ黒な画面がシミュレータで立ち上がる。
終了は、

(main)>>exit

1	(main)>>exit

でいいのかな。

古いXcodeを入れたままにしている人はRubyMotion1.2以降だと、

$ 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
===============================================================================

$ rake

っていうエラーが出て、デフォルトでiOS5.0が使われちゃう（あといろいろバグあるらしい）ので、
$ sudo xcode-select -switch /Applications/Xcode.app/Contents/Developer
しておきましょう。

と思ったけど、これやったら、

2012-05-07 22:23:22.621 Hello[8270:f803] Could not find mapped image ColorOnGrayShadow_DataType4G_2only_.png

1	2012-05-07 22:23:22.621 Hello[8270:f803] Could not find mapped image ColorOnGrayShadow_DataType4G_2only_.png

っていうエラーと共にアプリのステータスバーが消えて起動できなくなっちゃったので、

$ sudo xcode-select -switch /Developer

1	$ sudo xcode-select -switch /Developer

で戻した。
すぐ修正されるだろうから、とりあえずですね。

ダメ元で今日同じ手順でxcode-selectしたら問題なく動くようになってた。
何だったんだろ？？

アラート表示

次はお馴染みのHello, world!
ドキュメントの通り、

$  vim app/app_delegate.rb
class AppDelegate
  def application(application, didFinishLaunchingWithOptions:launchOptions)
    alert = UIAlertView.new
    alert.message = "Hello World!"
    alert.show
    true
  end
end

$ vim app/app_delegate.rb

class AppDelegate

def application(application, didFinishLaunchingWithOptions:launchOptions)

alert = UIAlertView.new

alert.message = "Hello World!"

alert.show

true

end

とすれば問題なく表示された。

実機転送（断念）

$ rake device

1	$ rake device

ってやれば実機転送出来るって書いてあったので、Provisioning Profileとかどうすんの？と思いながらやってみた。

error: DeviceOSVersionTooLow

1	error: DeviceOSVersionTooLow

手元のiPhoneがiOS4.3だったorz。
RubyMotion Project Management Guideに従って、

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

Motion::Project::App.setup do |app|
  # Use `rake config' to see complete project settings.
  app.name = 'Hello'
  app.deployment_target = "4.3"
  app.identifier = "com.bornneet.motionHello"
end

$:.unshift("/Library/RubyMotion/lib")

require 'motion/project'

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

# Use `rake config' to see complete project settings.

app.name = 'Hello'

app.deployment_target = "4.3"

app.identifier = "com.bornneet.motionHello"

end

な感じでdeployment targetを指定してやる。（ちなみに、おんなじ要領でprovisioning profileも変更できるっぽい。）
いざ！！

    ERROR! iOS deployment target 4.3 is not supported by this version of RubyMotion

1	ERROR! iOS deployment target 4.3 is not supported by this version of RubyMotion

まじすか…。

ちょっと手元の4.3の環境を失いたくないので一旦実機転送は諦める方向で。

だいぶわかってきたので（本当か？）次はもうちょいちゃんとしたアプリを作ってみよう。
