UIStackView动态添加两个相邻的标签,没有额外的间距

我有两个 UILabel 添加到 UIStackView

let horizontalStackView1 = UIStackView(arrangedSubviews: [self.label1, self.label2])

当我运行应用程序时,它看起来是这样的:

我试过了 horizontalStackView1.distribution , horizontalStackView1.alignment

我如何做到这一点?

提前谢谢!

代码如下所示(顺便说一下,它是一个表的单元格):

class ItemTableViewCell: UITableViewCell
{
    ...
    let stateLabel = UILabel()
    let effectiveDateLabel = UILabel()
    ...

    var typeImage: UIImage?
    {
        ...
    }

    var summary: String?
    {
        ...
    }

    var effectiveDate: Date?
    {
        ...
    }

    override init(style: UITableViewCellStyle, reuseIdentifier: String?)
    {
        super.init(style: style, reuseIdentifier: reuseIdentifier)
        self.accessoryType = .disclosureIndicator
        ...
        let horizontalStackView1 = UIStackView(arrangedSubviews: [self.stateLabel, self.effectiveDateLabel])
        let horizontalStackView2 = UIStackView(arrangedSubviews: [typeImageViewWrapper, self.titleLabel])
        horizontalStackView2.spacing = 4
        let verticalStackView = UIStackView(arrangedSubviews: [horizontalStackView1, horizontalStackView2, self.summaryLabel])
        verticalStackView.axis = .vertical
        verticalStackView.spacing = 4
        self.contentView.addSubview(verticalStackView)
        ...
    }

    required init?(coder aDecoder: NSCoder)
    {
        fatalError()
    }
}
