class Greeter def initialize(name) @name = name.capitalize end
def salute puts "Hello #{@name}!" endend

Objective-C와 루비
• 스몰토크• 카테고리 / 열린 클래스
• 오리 타이핑

왜 루비를?
• 재미, 생산성
• GC
• DSL -> 적은 코드
• attr_accessor :foo
• 익숙한 문법
• 스몰토크에 더 가깝다
18
어떻게?
• Objective-C 객체를 내부적으로 관리
• 프록시• 메시지와 예외를 전달
• 객체 변환
19
NSString *stringURL = @"http://deepblue.springnote.com/";
[[NSWorkspace sharedWorkspace] openURL:[NSURL URLWithString:stringURL]
];
url = NSURL.URLWithString('http://deepblue.springnote.com')
NSWorkSpace.sharedWorkspace.openURL(url)

[coder encodeObject:personName forKey:@'personName'];
