구문 분석에서 Excel 파일로 데이터를 저장하고 전자 메일로 보내기

Question

내가 묻는 질문을 더 잘 이해할 수 있도록 만든 그림을 봅니다. 내가 엑셀 ​​정보의 모든 IOS를 가지고 웹 사이트는 여기

http://www.appcoda.com/ios-programming-save-data-parse-cloud-tutorial/

을 그리고 :

또한, 여기에 내가 구문 분석하는 텍스트 필드의 구원을 얻었다 튜토리얼입니다

http : // libxl.com/download.html

구문 분석 할 데이터를 저장하고 표시 할 수도 있습니다. 또한 수동으로 .xls (Excel) 파일을 만들어 이메일을 통해 다른 사람에게 보낼 수도 있습니다. 지금해야 할 일은 .xls 파일에 내가 파싱 한 데이터를 채우는 것입니다. 여기

이 프로젝트는 거의

뭐든지 도움이 될 것입니다 난 그냥 도움이 마지막 비트를 필요로 이루어집니다

// 여기에을 편집하면 PFQuery를 사용하여 Parse.com에서 데이터를 검색 할 수 있습니다. 이 https://parse.com/docs/ios_guide#objects-retrieving/iOS을 따르고 데이터 구조에 맞게 수정하십시오.

데이터 구조가 확실하지 않은 경우. 구문 분석에 로그인하여 앱의 데이터 브라우저로 이동하십시오. https://parse.com/apps/YOUR_APP_NAME/collections과 같아야합니다. 필드를 클릭하고 JSON 데이터를 찾으십시오. PFQuery는 NSDictionary를 얻을 것이다. NSString을 사용하여 원하는 데이터를 검색 할 수 있습니다.
