与UILabel字体高度大小相同的UIImageView高度。在UIStackView内部居中

// 创建UIStackView
let stackView = UIStackView()
stackView.axis = .vertical
stackView.alignment = .center
stackView.spacing = 10

// 创建UILabel
let label = UILabel()
label.text = "Hello World"
label.font = UIFont.systemFont(ofSize: 20)

// 创建UIImageView
let imageView = UIImageView()
imageView.image = UIImage(named: "image")

// 将UILabel和UIImageView添加到UIStackView中
stackView.addArrangedSubview(label)
stackView.addArrangedSubview(imageView)

// 设置UIImageView的高度与UILabel的字体高度相同
imageView.heightAnchor.constraint(equalTo: label.font.lineHeight).isActive = true

// 将UIStackView添加到父视图中
parentView.addSubview(stackView)

// 使用Auto Layout约束来布局UIStackView
stackView.translatesAutoresizingMaskIntoConstraints = false
stackView.centerXAnchor.constraint(equalTo: parentView.centerXAnchor).isActive = true
stackView.centerYAnchor.constraint(equalTo: parentView.centerYAnchor).isActive = true
