RubyMotionは、iOSのための革新的な製品です。

RubyMotionを使えば、iPhoneやiPad向けのネイティブアプリを
素早く開発・テストすることができます。
使うのはみんなが知っていて大好きな

素晴らしいRuby言語だけ。

etc. etc.

Objective C to RubyMotion

[string drawAtPoint:point withFont:font];
string.drawAtPoint(point, withFont:font)

1. UIAlertView object作成
2. メッセージ設定
3. 表示

Although you can use new to
instantiate an Objective-C
class, I strongly recommend
you use alloc.init or related
constructors deﬁned by the
class.
