NSXMLParser 문제

Question

NSXMLParser를 사용하여 XML 파일을 구문 분석하므로 RSS 피드의 데이터를 테이블보기로 표시 할 수 있습니다. 그러나 제목 데이터는 올바르게 구문 분석되어 적절한 배열로 전달되지만 값을 셀 제목에 전달하면 모든 제목 뒤에 세 개의 마침표가 나타납니다. 셀에 전달되기 전에 콘솔에 값을 기록하고 텍스트 줄에 마침표가 없습니다. 또한 게시 날짜는 무엇이든지 상관없이 null을 반환합니다.

디버그 : 내가 처음에 "..."각 제목 후에 원인이 무엇인지 파악하지 않은 그러나

Answer 1

또는 그것을 고치는 방법, 나는 그 일을 잘하는 주변의 간단한 일에왔다. `당신이 추가되는지; [문자열 mutttitle appendString]`:

NSString *RSSTitle = nil; 
RSSTitle = [titarry objectAtIndex:indexPath.row]; 
RSSTitle = [RSSTitle substringToIndex:[RSSTitle length] - 3]; 
cell.nameLabel.text= RSSTitle;
