Swift 使用UIScrollView和自动布局的图像滑块

我正在尝试使用scrollView和pageControl实现一个图像滑块，并使用.addSubView方法以编程方式将图像附加到scrollView。代码如下：

@IBOutlet weak var sliderScrollView: UIScrollView!
@IBOutlet weak var sliderPageControl: UIPageControl!
var images: [String] = ["0", "1", "2"]

func updateSlider() {
        sliderPageControl.numberOfPages = images.count

        for index in 0..<images.count {
            frame.origin.x = sliderScrollView.frame.size.width * CGFloat(index)
            print(sliderScrollView.frame.size.width)
            frame.size = sliderScrollView.frame.size

            let image = UIImageView(frame: frame)
            image.contentMode = .scaleAspectFill
            image.image = UIImage(named: cafeObject.images[index])
            sliderScrollView.addSubview(image)
        }
        sliderScrollView.contentSize = CGSize(width: sliderScrollView.frame.size.width * CGFloat(cafeObject.images.count), height: sliderScrollView.frame.size.height)
        sliderScrollView.delegate = self
        sliderPageControl.currentPage = 0
}

override func scrollViewDidScroll(_ scrollView: UIScrollView) {
    let pageNumber = scrollView.contentOffset.x / scrollView.frame.size.width

    switch scrollView {
    case sliderScrollView:
        sliderPageControl.currentPage = Int(pageNumber)
    default:
        break
    }
}

@ibvar-sliderScrollView:UIScrollView！
@IBVAR sliderPageControl:UIPageControl！
变量图像：[字符串]=[“0”、“1”、“2”]
func updateSlider（）{
sliderPageControl.numberOfPages=images.count
对于0中的索引。好的，我通过将updateSlider（）函数放在
viewdilayoutsubviews（）下来解决这个问题。
