위의 사진과 같이 장소등록 버튼을 누르면 옆의 검색창으로 이동한 뒤, 주소를 입력하면 주르륵 자동 완성 셀이 나오는 형식입니다그러나 어찌된 영문인지 셀은 코빼기도 안보입니다ㅠㅠㅠㅠㅠㅠ
//검색창 뷰 컨트롤러인 LocationSearchViewController.swift파일

사람 한 명 살려주세요ㅠㅠㅠㅠㅠㅠ

첨부해주신 코드만 봤을 땐
tableView의dataSource를 설정해주지 않아서 셀이 나타나지 않는 것 같네요 🤔-
extension LocationSearchViewController: UITableViewDataSource {
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return completerResults?.count ?? 0
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
guard let cell = tableView.dequeueReusableCell(withIdentifier: “Cell”) as? Cell else { return UITableViewCell() }
if let suggestion = completerResults?[indexPath.row] {
cell.titleLabel.text = suggestion.title
cell.subtitleLabel.text = suggestion.subtitle
}
return cell
}
이렇게 extension으로 dataSource 설정되어있는데도 그러네요ㅠㅠㅠㅠ
-
혹시 선언하신 tableView의 dataSource로 UITableViewDataSource 프로토콜을 채택한 객체(LocationSearchViewController)를 할당해주셨을까요?

해결했습니다! 감사합니다!!
