如何在连续间隔的约束布局中居中两个文本视图？

// 创建第一个文本视图
let firstLabel = UILabel()
firstLabel.text = "First Label"
firstLabel.translatesAutoresizingMaskIntoConstraints = false
view.addSubview(firstLabel)

// 创建第二个文本视图
let secondLabel = UILabel()
secondLabel.text = "Second Label"
secondLabel.translatesAutoresizingMaskIntoConstraints = false
view.addSubview(secondLabel)

// 设置第一个文本视图的约束
NSLayoutConstraint.activate([
    firstLabel.leadingAnchor.constraint(equalTo: view.leadingAnchor, constant: 20),
    firstLabel.trailingAnchor.constraint(equalTo: secondLabel.leadingAnchor, constant: -20),
    firstLabel.centerYAnchor.constraint(equalTo: view.centerYAnchor)
])

// 设置第二个文本视图的约束
NSLayoutConstraint.activate([
    secondLabel.trailingAnchor.constraint(equalTo: view.trailingAnchor, constant: -20),
    secondLabel.centerYAnchor.constraint(equalTo: view.centerYAnchor)
])
