UIKit - UITableView 스와이프 버튼 구현하기

UITableView의 Delegate 메서드를 구현하여 스와이프 액션을 처리할 수 있음.

ViewController.swift

import UIKit

final class ViewController: UIViewController {

    // UITableView 인스턴스 생성
    private let tableView = UITableView()
    
    ...


    override func viewDidLoad() {
      super.viewDidLoad()

      // viewDidLoad 시점에 호출
      setupTableView()
    }


    func setupTableView(){
        ....
        
        // Delegate 설정
        tableView.delegate = self
        
        ...
    }
}

// MARK: - 테이블뷰 Delegate
extension ViewController: UITableViewDelegate{
    
    // 오른쪽 스와이프 처리
    func tableView(_ tableView: UITableView, trailingSwipeActionsConfigurationForRowAt indexPath: IndexPath) -> UISwipeActionsConfiguration? {
        
        // 삭제 버튼 설정
        let deleteButton = UIContextualAction(style: .destructive, title: nil) { _, _, success in
            print("\(indexPath.row) 삭제 버튼 클릭")
            success(true)
        }
        
        deleteButton.image = UIImage(systemName: "trash")
        
        return UISwipeActionsConfiguration(actions: [deleteButton])
    }
}

결과
