Question

我正在尝试使StackView内容可滚动。我插入虚拟UIImage视图，试图让它工作，但它不滚动。堆栈和滚动视图已连接到IB。我错过了什么？

import UIKit

class ViewController: UIViewController {

    @IBOutlet weak var menuStackView: UIStackView!
    @IBOutlet weak var menuScrollView: UIScrollView!
    override func viewDidLoad() {
        super.viewDidLoad()
        // Do any additional setup after loading the view, typically from a nib.


        var itemImageView = UIImageView(image: UIImage(named: "splash2"))
        itemImageView.contentMode = .ScaleAspectFit
        self.menuStackView.addArrangedSubview(itemImageView)

        itemImageView = UIImageView(image: UIImage(named: "splash2"))
        itemImageView.contentMode = .ScaleAspectFit
        self.menuStackView.addArrangedSubview(itemImageView)

        itemImageView = UIImageView(image: UIImage(named: "splash2"))
        itemImageView.contentMode = .ScaleAspectFit
        self.menuStackView.addArrangedSubview(itemImageView)

        itemImageView = UIImageView(image: UIImage(named: "splash2"))
        itemImageView.contentMode = .ScaleAspectFit
        self.menuStackView.addArrangedSubview(itemImageView)

        itemImageView = UIImageView(image: UIImage(named: "splash2"))
        itemImageView.contentMode = .ScaleAspectFit
        self.menuStackView.addArrangedSubview(itemImageView)

        itemImageView = UIImageView(image: UIImage(named: "splash2"))
        itemImageView.contentMode = .ScaleAspectFit
        self.menuStackView.addArrangedSubview(itemImageView)

        itemImageView = UIImageView(image: UIImage(named: "splash2"))
        itemImageView.contentMode = .ScaleAspectFit
        self.menuStackView.addArrangedSubview(itemImageView)


        itemImageView = UIImageView(image: UIImage(named: "splash2"))
        itemImageView.contentMode = .ScaleAspectFit
        self.menuStackView.addArrangedSubview(itemImageView)


    }

    override func viewDidLayoutSubviews() {
        super.viewDidLayoutSubviews()
        menuScrollView.contentSize = CGSize(width: menuStackView.frame.width, height: menuStackView.frame.height)

    }
}

我的想法是创建一个用你设置你的滚动视图的UIView。然后将堆栈视图添加到该内容视图。因为否则，为了使stackview像你想要的那样工作，我不得不在滚动视图的所有边上添加约束并添加高度和宽度约束。

我也在这里回答了一个类似的问题，可能有所帮助：

这是指向一个带有滚动堆栈视图的项目的链接，您可以使用它来重新开始：

我无法让UIScrollView与UIStackView一起使用
