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'];

coder.encodeObject_forKey(personName, 'personName')
