有没有一种简单的方法来获取 UIStackView 的总内容大小？

举个例子：

我以编程方式创建了一个 UIViews 数组...

var numberOfSubViews = 5

let subViews: [UIView] = {
var array: [UIView] = []

for _ in 0..<numberOfSubViews {
    let height: CGFloat = 40
    let width: CGFloat = 100

    let subView = UIView(frame: CGRect(x: 0, y: 0, width: width, height: height))
    subView.widthAnchor.constraint(equalToConstant: width).isActive = true
    subView.heightAnchor.constraint(equalToConstant: height).isActive = true

    array.append(subView)
}

return array
}()

然后我从该数组创建一个简单的 UIStackView ...

var spacing: CGFloat = 4

let stackView = UIStackView(arrangedSubviews: subViews)
stackView.axis = .horizontal
stackView.spacing = spacing …
