배열을 내 사용자 정의 셀 클래스에 전달하는 방법

Question

pickerview가있는 사용자 정의 셀 클래스가있는 TableView가 있습니다.

데이터를 pickerview에 채우기 위해 배열을 전달하고 싶습니다. 그것을 전달하는 방법. 내 접근 방식이 맞습니까?

Answer 1

TableViewCell에 아무 것도 전달하지 않습니다. 대신 당신은있는 tableView를 채우는

• UITableViewDelegate
• UITableViewDatasource

를 구현해야합니다. 그리고 선택기에 대한

• UIPickerViewDelegate
• UIPickerViewDatasource

.

Answer 2

테이블 셀 내에 pickerview 대리자 및 데이터 소스가 포함되어 있으며 정상적으로 작동합니다. 배열을 전달하는 것은 모든보기와 동일합니다.
