我不能讓UIScrollView與UIStackView一起工作

Question

我想讓StackView內容可以滾動。我插入了虛擬UIImage視圖來試圖讓它工作，但它不滾動。堆棧和滾動視圖已經連接到IB。我錯過了什麼？

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) 

    } 
}

我的想法是創建一個UIView，你設置你的滾動視圖。然後將堆棧視圖添加到該內容視圖。因爲不然的話，爲了使堆棧視圖像你想要的那樣工作，我必須在它的所有面上添加約束到滾動視圖並添加高度和寬度約束。

我也回答了在這裏過類似的問題，這可能有助於：

而這裏的鏈接到一個項目，一個工作滾動stackview，你可以用它來獲得再次去：
