更改UIView图层-Swift

Question

我尝试用序列实现UIView。使用下面的代码，输出如图所示。 （这是正常行为）

但是我想像下面的图片一样排队

从右到右排序的元素！

imageView.trailingAnchor.constraint(equalTo: participantView.safeAreaLayoutGuide.trailingAnchor, constant: CGFloat(-(counter * widthX - 5 * counter)) ).isActive = true

我现在该怎么办？

   let widthX = 30
   var counter = 0
   for x in element {

          guard let image = x.image else { continue }
          let urlX = URL(string: "...")
          let imageView = UIImageView()
          participantView.addSubview(imageView)

          imageView.translatesAutoresizingMaskIntoConstraints = false
          imageView.trailingAnchor.constraint(equalTo: participantView.safeAreaLayoutGuide.trailingAnchor, constant: CGFloat(-(counter * widthX - 5 * counter)) ).isActive = true
          imageView.topAnchor.constraint(equalTo: participantView.topAnchor, constant: 0).isActive = true
          imageView.bottomAnchor.constraint(equalTo: participantView.bottomAnchor, constant: 0).isActive = true
          imageView.widthAnchor.constraint(equalToConstant: 30).isActive = true
          imageView.backgroundColor = .white

          imageView.layer.cornerRadius = 15
          imageView.clipsToBounds = true
          imageView.contentMode = .scaleAspectFit
          imageView.layer.borderWidth = 1
          imageView.layer.borderColor = UIColor.lightGray.cgColor
          counter += 1

          imageView.kf.setImage(with: urlX)
   }

Answer 1

替换

participantView.addSubview(imageView)

使用

participantView.insertSubview(imageView,at:0)

1，2 ..etc（左右对齐）的位置取决于图像
