iPhone, JSON의 특수 문자 응답

Question

iphone 앱을 쓰고 JSON을 반환하는 REST API에서 데이터를 가져옵니다. 내 문제는 일부 데이터에 특수 문자가 포함되어있어 오류가 발생한다는 것입니다. 예 : 그렇지 않으면 모든 것이 잘 작동, 데이터가 "jsonString"반환에 특수 문자가 때마다

NSString *jsonString = [[NSString alloc] 
          initWithData:receivedData 
          encoding:NSUTF8StringEncoding]; 
NSMutableArray *tempResults = [[[jsonString JSONValue] 
          objectForKey:@"getRegionResortsLastUpdatedResponse"] 
          objectForKey:@"return"];

여기 내 현재 코드입니다.

내 마지막으로 처리 할 수있는 것이거나 문자 코드를 출력하기 위해 API를 수정해야합니까?

Answer 1

-initWithData:encoding:이 nil을 반환하면 데이터가 요청한 인코딩으로 인코딩되지 않은 것입니다. 나는 UTF8을 보내지 않는다고 의심하고 Windows 코드 페이지 또는 Latin1 중 하나와 같은 다른 인코딩을 보내고 있습니다. NSString documentation에서 문자열 인코딩을 참조하십시오.
