iOS 개발을 처음 사용합니다. 현재, .plist 파일에서 데이터를 가져와 UITableView에 표시하려고합니다. 응용 프로그램을 실행하는 동안, 엑스 코드는 오류를 제공하지 않았다,하지만 내 응용 프로그램은 아무 것도 보여주지 그러나이iOS는 .plist 파일에서 데이터를로드합니다.

나는 문제를 알아낼 수하지 않았다. 그래서, 내 질문은 내 코드의 문제는 무엇입니까? 어떻게 plist 파일에서 데이터를 표시 할 수 있습니까? 나는 이전 질문을 stackoverflow에서 찾았지만 그게 도움이되지 못했습니다.

@ Yasir plist 데이터를 구문 분석 한 다음 tableview에로드해야합니다. 어레이에 정보가 있는지 한 번만 확인하십시오. Json 파서 사용 –
