水平 Stackview 左对齐项目

Question

我正在创建一个水平 UIStackView 并希望在其中左对齐项目。 这是我的代码：

let nameLabel: UILabel = {
    let label=UILabel()
    label.text = "First Name:"
    label.textColor = UIColor.black
    label.font = UIFont.systemFont(ofSize: 20)
    label.textAlignment = .left
    label.translatesAutoresizingMaskIntoConstraints=false
    return label
}()

let nameTextField: UITextField = {
    let label=UITextField()
    label.placeholder = "Enter Name"
    label.textColor = UIColor.darkGray
    label.font = UIFont.systemFont(ofSize: 18)
    label.textAlignment = .left
    label.isUserInteractionEnabled = false
    label.translatesAutoresizingMaskIntoConstraints=false
    return label
}()

lazy var firstNameView: UIStackView = {
    let stackView = UIStackView(arrangedSubviews: [self.nameLabel, self.nameTextField])
    stackView.translatesAutoresizingMaskIntoConstraints = false;
    stackView.axis = .horizontal
    stackView.distribution = .fill
    stackView.alignment = .center
    stackView.spacing = 10.0
    return stackView
}()

这就是我如何将它添加到视图中

self.view.addSubview(firstNameView)

firstNameView.leadingAnchor.constraint(equalTo: self.view.leadingAnchor).isActive = true;
    firstNameView.topAnchor.constraint(equalTo: idLabel.bottomAnchor).isActive = true;
    firstNameView.trailingAnchor.constraint(equalTo: self.view.trailingAnchor).isActive = true
    firstNameView.heightAnchor.constraint(equalToConstant: 40.0).isActive = true

我还尝试了以下方法：

firstNameView.trailingAnchor.constraint(greaterThanOrEqualTo: self.view.trailingAnchor).isActive = true

PS：这个问题与UIStackview align left 不同，因为我说的是水平堆栈视图

根据此链接Left aligned horizontal stackview and top aligned vertical stackview 有没有其他选择，我真的不想设置固定宽度。

Answer 1

将标签包装在 UIView 中，并将标签固定在这些视图的左侧。将视图放入堆栈视图，它们将填充堆栈视图而无需操作标签。
