在 UITableView 中对齐多个运行时生成的 UILabels

我有一个UITableView需要通过列出类似的样式来支持内容

But the tricky part is that the amount of "Label" will vary with each cell, some may have only 4 but also up to 12. Also the "Value" can be either a single word or short phrase up to two lines(like in the image above). So I decided to use UIStackView to help me pack and size my UILabels used to display this. I am currently stuck at a problem when the "Label" varies in length like:

我需要“值”的前端像第一张图像一样对齐，即使“标签”的长度不同。是否存在以下行为UIStackView这允许吗？或者有其他方法可以让我获得我需要的结果吗？

注意：每个“标签”和“值”都在一个UIStackView，我这样做是为了对齐它们。

我也尝试过使用字符串格式，但是超过一行的“值”将包裹在标签下，而不是像我在图像中所做的那样自行包裹。

我尝试将所有“标签”放在一个中UIStackView以及另一张中的所有“值”，一旦“值”超过一行，我就无法让它们像图像中那样对齐。

或者，如果这可能是我在某个地方犯的错误，这就是我创建的方式UIStackViews:

    var higherCount = 0
    if labels.count<values.count {
        higherCount = values.count
    } else {
        higherCount = labels.count
    }

    mainStackView = UIStackView(frame: CGRect(x: 0, y: 0, width: frame.width, height: frame.height))

    for i in 0..<higherCount {
        var height:CGFloat = 20
        if (values[i] as NSString).size(attributes: [NSFontAttributeName:UIFont.systemFont(ofSize: UIFont.systemFontSize)]).width > frame.width {
            height = 42
        }

        let stackViewToAdd = UIStackView(frame: CGRect(x: 0, y: 0, width: frame.width, height: height))

        let label = UILabel(frame: CGRect(x: 0, y: 0, width: frame.width, height: height))
        if labels.count<higherCount {
            label.text = ""
        } else {
            label.text = labels[i]
        }
        label.setContentCompressionResistancePriority(1000, for: .horizontal)
        label.setContentHuggingPriority(999, for: .horizontal)
        stackViewToAdd.addArrangedSubview(label)
        let value = UILabel(frame: CGRect(x: 0, y: 0, width: frame.width, height: height))
        if values.count<higherCount {
            value.text = ""
        } else {
            value.text = values[i]
        }
        value.lineBreakMode = .byWordWrapping
        value.numberOfLines = 2
        stackViewToAdd.addArrangedSubview(value)
        mainStackView?.addArrangedSubview(stackViewToAdd)
    }
    mainStackView?.alignment = .fill
    mainStackView?.axis = .vertical
    mainStackView?.distribution = .fill

如果您以编程方式创建了单元格，那么您可以根据 UILabel 内容的大小以编程方式调整单元格的大小。

就我而言Label字体是UIFont.systemFont(ofSize: 15)，最小 TableViewCell 高度为 50，arrLabel1 and arrLabel2将是标签的内容。

func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
    return arrLable1.count
}

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
    let cell = UITableViewCell(style: .default, reuseIdentifier: "\(indexPath.row)")

    let lable1 = UILabel(frame: CGRect(x: 10, y: 10, width: view.frame.size.width - 20, height: 0))
    lable1.numberOfLines = 0
    lable1.font = UIFont.systemFont(ofSize: 15)
    lable1.text = arrLable1[indexPath.row]
    lable1.sizeToFit()
    cell.addSubview(lable1)

    let lable2 = UILabel(frame: CGRect(x: 10, y: lable1.frame.origin.y + lable1.frame.size.height + 10 , width: view.frame.size.width - 20, height: 0))
    lable2.numberOfLines = 0
    lable2.font = UIFont.systemFont(ofSize: 15)
    lable2.text = arrLable2[indexPath.row]
    lable2.sizeToFit()
    cell.addSubview(lable2)

    return cell
}

func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath)
    -> CGFloat {

    let boundingRect1 = arrLable1[indexPath.row].boundingRect(with: CGSize(width: view.frame.size.width - 40 , height: CGFloat(MAXFLOAT)), options: NSStringDrawingOptions.usesLineFragmentOrigin,attributes:[ NSFontAttributeName : UIFont.systemFont(ofSize: 15)] ,context: nil)

    let boundingRect2 = arrLable2[indexPath.row].boundingRect(with: CGSize(width: view.frame.size.width - 40 , height: CGFloat(MAXFLOAT)), options: NSStringDrawingOptions.usesLineFragmentOrigin,attributes:[ NSFontAttributeName : UIFont.systemFont(ofSize: 15)] ,context: nil)

    guard boundingRect1.height + boundingRect2.height + 30 > 50 else {
        return 50
    }

    return boundingRect1.height + boundingRect2.height + 30
}

Set Label行数为 0
