스택보기 (및 / 또는 콘텐츠보기)가 포함 된 스크롤보기가 예상대로 작동하지 않음

여기에 효과가있는 예가 있습니다. 당신이 무엇을 다르게했는지 알아낼 수 있는지 확인하세요.

"컨텐츠 뷰"를 사용하는 대신 코드를 통해 스크롤 뷰에 직접 스택 뷰를 추가합니다.

스토리 보드 레이아웃은 다음과 같습니다.

다음은 스토리 보드의 소스이므로 직접 검토 할 수 있습니다.

다음은 스크롤 뷰에 스택 뷰를 추가하고 스택 뷰에 40 개의 레이블을 추가 한 다음 스택 뷰를 스크롤 뷰로 적절하게 제한하는 예제 코드입니다.

class KevvvViewController: UIViewController {

    @IBOutlet var scrollView: UIScrollView!
    
    override func viewDidLoad() {
        super.viewDidLoad()

        let stack = UIStackView()
        stack.axis = .vertical
        stack.spacing = 12
        
        stack.translatesAutoresizingMaskIntoConstraints = false
        
        scrollView.addSubview(stack)
        
        for i in 1...40 {
            let v = UILabel()
            v.backgroundColor = .yellow
            v.text = "Label \(i)"
            stack.addArrangedSubview(v)
        }

        NSLayoutConstraint.activate([
            stack.topAnchor.constraint(equalTo: scrollView.contentLayoutGuide.topAnchor),
            stack.leadingAnchor.constraint(equalTo: scrollView.contentLayoutGuide.leadingAnchor),
            stack.trailingAnchor.constraint(equalTo: scrollView.contentLayoutGuide.trailingAnchor),
            stack.bottomAnchor.constraint(equalTo: scrollView.contentLayoutGuide.bottomAnchor),
            
            stack.widthAnchor.constraint(equalTo: scrollView.frameLayoutGuide.widthAnchor),
        ])
        
        // to make it easy to see the scroll view frame
        scrollView.backgroundColor = .cyan
    }
    
}

결과 : 17 번째 레이블 (iPhone 8)까지 아래로 스크롤 한 후 :
