UIScrollView 与 UIViewRepresentable 中的 UIImageView

Question

我正在尝试将 UIImageView 添加到 UIViewRepresentable 内部的 UIScrollView 中。 我还试图在 UIScrollView 中展示带有.scaleAspectFill 的 UIImageView。 不幸的是，UIScrollView 忽略了.scaleAspectFill 并放大到 UIImageView。 简而言之-> 在 UIScrollView 内显示一个带有 .scaleAspectFill 的 UIImageView，以便滚动到 .scaleAspectFill 截断的图像部分。

这是我的代码：

struct ShowImage: View {

var body: some View {
    
    ZStack {
        
        UIImageViewRepresentable()
        
    }
}

}

结构 UIImageViewRepresentable: UIViewRepresentable {

func makeUIView(context: Context) -> UIScrollView {

    let scrollView = UIScrollView()
    scrollView.showsVerticalScrollIndicator = true
    scrollView.showsHorizontalScrollIndicator = true
    scrollView.bounces = false
    scrollView.backgroundColor = .blue
    scrollView.isScrollEnabled = true
    scrollView.contentMode = .scaleAspectFill
   
    let imageView = UIImageView()
    let image = UIImage(named: "5")!
    imageView.setContentCompressionResistancePriority(.defaultLow, for: .horizontal)
    imageView.setContentCompressionResistancePriority(.defaultLow, for: .vertical)
    imageView.contentMode = .scaleAspectFill
    imageView.clipsToBounds = true
    imageView.image = image
    imageView.translatesAutoresizingMaskIntoConstraints = false
    imageView.frame.size = image.size
    
    scrollView.contentSize = imageView.image!.size
    scrollView.addSubview(imageView)
    
    return scrollView
}

func updateUIView(_ uiView: UIViewType, context: Context) {
    
}

func makeCoordinator() -> ShowImageCoordinator {
    return ShowImageCoordinator()
}

}
