如何在一行中垂直对齐两个UILabels？

// 创建UILabel对象
let label1 = UILabel()
let label2 = UILabel()

// 设置UILabel的属性
label1.text = "Label 1"
label2.text = "Label 2"
label1.font = UIFont.systemFont(ofSize: 16)
label2.font = UIFont.systemFont(ofSize: 16)
label1.textColor = UIColor.black
label2.textColor = UIColor.black

// 添加UILabel到父视图上
view.addSubview(label1)
view.addSubview(label2)

// 禁用AutoresizingMask
label1.translatesAutoresizingMaskIntoConstraints = false
label2.translatesAutoresizingMaskIntoConstraints = false

// 设置约束条件
NSLayoutConstraint.activate([
    // label1的左边缘与父视图左边缘对齐
    label1.leadingAnchor.constraint(equalTo: view.leadingAnchor),
    // label2的左边缘与label1的右边缘对齐
    label2.leadingAnchor.constraint(equalTo: label1.trailingAnchor, constant: 8),
    // label2的右边缘与父视图右边缘对齐
    label2.trailingAnchor.constraint(equalTo: view.trailingAnchor),
    // label1和label2的顶部对齐
    label1.topAnchor.constraint(equalTo: view.topAnchor),
    label2.topAnchor.constraint(equalTo: view.topAnchor),
    // label1和label2的底部对齐
    label1.bottomAnchor.constraint(equalTo: view.bottomAnchor),
    label2.bottomAnchor.constraint(equalTo: view.bottomAnchor)
