TableViewController 연락처가 표시되지 않습니다.

Question

저는 프로그래밍에 익숙하지 않습니다. 나는 C++의 거친 지식 기반을 가지고 있지만 objective-c는 완전히 새로운 것이다.

사용자가 연락처 목록에서 전자 메일받는 사람을 추가 할 것인지 묻는 응용 프로그램에서 간단한 UITableViewController를 구현하려고합니다. TableViewController가로드되지만 TableViewCell 데이터는로드되지 않습니다. 나는 iOS 개발자 라이브러리를 샅샅이 뒤졌고 정보는 쿠키 커터처럼 보인다. 예제 코드를 찾아 내 ViewController 파일에 복사/붙여 넣기했습니다. 내 파일을 준수하고 필요한 불필요한 전화를 삭제하고 필자가이 사이트에서 발견 한 모든 답변을 따라 내 문제를 원격으로 처리하는 데 필요한 사항을 변경했습니다 ... 아무 소용이 없습니다! 여기에 지금까지이 작업은 다음과 같습니다

미안! 어떤 코드 섹션이 문제와 가장 관련이 있는지 확실하지 않습니다.

* 많은 코드가 문제 해결을 위해 다소 압도적 인 경우이 문제에 대한 도움을 크게 주시면 감사하겠습니다. 오류나 문제가 나타나면 TableViewController가로드됩니다. 사용자에게 몇 번만 연락처에 대한 액세스를 허용하고 이후로는하지 않았습니다. 프롬프트가 표시 되더라도 시뮬레이터의 연락처로 이동하지 않았습니다. iOS 시뮬레이터에 연락처를 추가했습니다.

나는 어떤 도움에 진심으로 감사드립니다!

Answer 1

나는 모든 코드를 살펴 보지 못했지만 설명 된 문제는 주로 배열이 비어있을 때 발생합니다. 배열 내용의 NSLog를 objets를 추가하는 위치에 놓으십시오. 해당 수가 0보다 큰지 확인하십시오.

Answer 2

사용중인 iOS 버전은 무엇입니까? 그것이 나타나는지를 결정할 것입니다. iOS 7 일 경우 주소록을 볼 수있는 권한이 필요합니다. 추가 한 새로운 것입니다.
