ios - 如何根据铭文的长度设置布局锚？

Question

我想在同一行中使用两个 UILabel 设置 UITableViewCell。例如：汤姆福特。我知道如何以硬编码的方式进行操作，但是如何根据名字的长度来做呢？我的意思是名字的长度不同，我想在名字 UILabel 的右侧将姓氏 UILabel 设置为相同的长度。怎么做？

名字和姓氏：

func setFirstnameLabel() {
    firstNameLabel.translatesAutoresizingMaskIntoConstraints                                               = false
    firstNameLabel.centerYAnchor.constraint(equalTo: centerYAnchor).isActive                               = true
    firstNameLabel.leadingAnchor.constraint(equalTo: leadingAnchor, constant: 12).isActive                 = true
    firstNameLabel.heightAnchor.constraint(equalToConstant: 30).isActive                                   = true
    firstNameLabel.widthAnchor.constraint(equalToConstant: 100).isActive                                   = true
}

func setLastNameLabel() {
    lastNameLabel.translatesAutoresizingMaskIntoConstraints                                                = false
    lastNameLabel.centerYAnchor.constraint(equalTo: centerYAnchor).isActive                                = true
    lastNameLabel.leadingAnchor.constraint(equalTo: firstNameLabel.trailingAnchor, constant: 20).isActive  = true
    lastNameLabel.heightAnchor.constraint(equalToConstant: 30).isActive                                    = true
    lastNameLabel.trailingAnchor.constraint(equalTo: trailingAnchor, constant: -12).isActive               = true
}
