Swift:使用编程大小的UIViews制作垂直滚动提要

let scrollView = UIScrollView(frame: CGRect(x: 0, y: 0, width: view.frame.width, height: view.frame.height))
scrollView.contentSize = CGSize(width: view.frame.width, height: 1000)

let stackView = UIStackView()
stackView.axis = .vertical
stackView.spacing = 10

for i in 0..<10 {
    let subview = UIView()
    subview.backgroundColor = UIColor.random // 设置子视图的背景颜色，这里使用了一个自定义的UIColor扩展方法
    subview.heightAnchor.constraint(equalToConstant: 200).isActive = true // 设置子视图的高度
    stackView.addArrangedSubview(subview)
}

scrollView.addSubview(stackView)
stackView.translatesAutoresizingMaskIntoConstraints = false
stackView.leadingAnchor.constraint(equalTo: scrollView.leadingAnchor).isActive = true
stackView.trailingAnchor.constraint(equalTo: scrollView.trailingAnchor).isActive = true
stackView.topAnchor.constraint(equalTo: scrollView.topAnchor).isActive = true
stackView.bottomAnchor.constraint(equalTo: scrollView.bottomAnchor).isActive = true

view.addSubview(scrollView)
