My code for generating children stack views:
我生成子堆栈视图的代码：
@IBOutlet weak var parentStackView: UIStackView!
func addStackViewsToParentStackView(params: [String: Float]) {
for (name, value) in params {
let parameterNameLabel = UILabel() // first label
parameterNameLabel.text = name
let parameterValueLabel = UILabel() // second label
parameterValueLabel.text = value.description
parameterValueLabel.frame.size.width = 80.0 // I've tried to fix width, but it does't help
let childStackView = UIStackView(arrangedSubviews: [parameterNameLabel, parameterValueLabel])
childStackView.axis = .Horizontal
childStackView.distribution = .FillProportionally
childStackView.alignment = .Fill
childStackView.spacing = 5
childStackView.translatesAutoresizingMaskIntoConstraints = true
parentStackView.addArrangedSubview(childStackView)
}
}
Thanks for any help!

Just put width constraints on the labels.
只需在标签上设置宽度限制即可。
parameterValueLabel.widthAnchor.constraint(equalToConstant: 80).isActive = true
