[iOS프로그래밍 실무] 5주차

Delegate나 DataSource를 사용하는 UI 컴포넌트

 

스위프트 상속과 프로토콜 채택

 

TableView의 DataSource : UITableViewDataSource프로토콜

 

UITableViewDataSource프로토콜 : 선택적 메서드

 

TableView의 Delegate: UITableViewDelegate프로토콜

 

테이블뷰 관련 delegate, datasource 그림 그리기

한 칸 : 로우, 셀

 

UIViewController vs UIViewTableController

 

 

 

Pin Tool로 Add New Constraints : Table View를 화면 전체를 채움

import UIKit
var name = ["1한식", "2분식", "3중식", "4일식", "5양식"]
var image = ["1.png", "2.png", "3.png", "5.png", "6.png"]
class ViewController: UIViewController, UITableViewDataSource, UITableViewDelegate {
    
    @IBOutlet weak var table: UITableView!
    
    func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
        return 5
    }
    func numberOfSections(in tableView: UITableView) -> Int {
        return 6
    }
    
    func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
        
        let cell = UITableViewCell.init(style: .subtitle, reuseIdentifier: "myCell")
        cell.textLabel?.text = name[indexPath.row]//"\(indexPath.row)"
        cell.detailTextLabel?.text = "\"indexPath.row"
        cell.imageView?.image = UIImage(named: image[indexPath.row])
        return cell
    }
    
    override func viewDidLoad() {
        super.viewDidLoad()
        table.dataSource = self
        table.delegate = self
    }
}

 

Table View Cell을 직접 디자인 : Table View Cell 추가
