iPhone 프로젝트에 Matt Gemmell의 놀라운 MGTwitterEngine을 사용하고 있으며 Obj-C 및 JSON 구문 분석에 익숙하지 않아 간단한 작업이 다소 어려워 보입니다.목표 C에서 MGTwitterEngine으로 검색 결과 구문 분석
나는 this link을 읽었으며 데이터 구조화 방법을 이해하는 데 도움이되지만 여전히 구문 분석 할 수없는 것처럼 보입니다. 내가 그렇게 좋아 getSearchResultsForQuery의 출력의 NSLog를 할 경우
:
NSLog(@"getSearchResultsForQuery: connectionIdentifier = %@", [myTwitterEngine getSearchResultsForQuery:@"#joke" sinceID:0 startingAtPage:1 count:5]);
나는 콘솔이 얻을 :

이상한 것은 내가 계산이있다 : 5, 아직 I 더 많은 결과를 얻고 있습니다.
실제 구문 분석을 위해 출력을 NSArray에 저장 한 다음 valueForKey를 사용하여 쿼리 할 수있는 NSDictionary (예 : @ "text")를 저장하겠습니까?
두 개의 대리자 메서드가 너무 (requestSucceeded : 및 searchResultsReceived : forRequest :) 호출되고 있지만이 파싱에 어떻게 영향을 미치는지 잘 모르겠다.
searchResultsReceived의 실제 위임 방법 forRequest는 :이다
- (void)searchResultsReceived:(NSArray *)searchResults forRequest:(NSString *)connectionIdentifier
{
NSLog(@"Got search results for %@:\r%@", connectionIdentifier, searchResults);
}
이 결과는 실제의 SearchResult 변수가 저장되는 것을 의미한다.
그래도 개별 문자열을 얻으려면 어떻게해야합니까?
도움 주셔서 감사합니다.
고마워요! 이것은 내가 계속해서 데이터를 연구 할 수있는 방법을 제공합니다. 델리게이트 함수의 범위를 벗어난 개별 문자열에 액세스하려면 반환 형식을 Array로 설정하고 필요한 정보 만 반환 할 수 있습니까? 아니면 원래 배열 자체를 반환하여 추출을 수행 할 수 있습니까? 다시 고맙습니다. – Parimal
NSArray 인스턴스 변수 (ivar) 속성을 만들고 그 위에 고정시킬 수 있습니다 (예 : [self setItems : searchResults]; 이것은 인스턴스 변수가 @property (assign) NSArray * items와 같은 속성으로 선언 될 것을 요구합니다; .h를 입력 한 다음 .m의 항목을 @synthesize하십시오. –
오, 훌륭합니다! 도와 주셔서 정말 감사합니다! – Parimal
