StroyBoardUI로 구현

 

import UIKit

class ViewController: UIViewController {
    
    private var number: Int = 0
    
    

    @IBOutlet weak var label: UILabel!
    
    
    @IBOutlet weak var minusButton: UIButton!
    
    @IBAction func minusButtonTapped(_ sender: Any) {
        self.number -= 1
        label.text = "\(self.number)"
    }
    
    @IBOutlet weak var plusButton: UIButton!
    
    @IBAction func plusButtonTapped(_ sender: Any) {
        self.number += 1
        label.text = "\(self.number)"
    }
    
    override func viewDidLoad() {
        super.viewDidLoad()
        // Do any additional setup after loading the view.
    }


}

Level.1 구현

• 속성
  • backgroundColor = .black
  • textColor = .white
  • 텍스트는 12345로 고정
  • 텍스트 오른쪽 정렬
  • Font = 시스템 볼드체, 사이즈 60
• AutoLayout
  • leading, trailing = superView 로부터 30 떨어뜨리기
  • top = superView 로부터 200 떨어뜨리기
  • height = 100

• UIButton 속성
  • font = .boldSystemFont(ofSize: 30)
  • backgroundColor(red: 58/255, green: 58/255, blue: 58/255, alpha: 1.0)
  • frame.size.height = 80
  • frame.size.width = 80
  • layer.cornerRadius = 40
• horizontalStackView 속성
  • axis = .horizontal
  • backgroundColor = .black
  • spacing = 10
  • distribution = .fillEqually
• horizontalStackView AutoLayout
  • height = 80
• verticalStackView 속성
  • axis = .vertical
  • backgroundColor = .black
  • spacing = 10
  • distribution = . fillEqually
• horizontalStackView AutoLayout
  • width = 350
  • top = label의 bottom으로부터 60 떨어지도록
