【问题描述】：

var monthsOfNonWorking = ["1. mēnesis","2. mēnesis","3. mēnesis","4. mēnesis","5. mēnesis","6. mēnesis","7. mēnesis","8. mēnesis","9. mēnesis",]        

@IBAction func nonWorkingAllowanceCalculate(_ sender: Any) 

    var firstThreeMonths :Double
    var secondThreeMonths :Double
    var LastThreeMonths :Double

    let bezdarbienieka_alga = Double(bezd_alga.text!)


    if (staza_masiva_lasisana == 0) 

        firstThreeMonths = Double(bezdarbienieka_alga! / 2)

        secondThreeMonths = Double(firstThreeMonths / 2)

        LastThreeMonths = Double(bezdarbienieka_alga! / 1.6 - secondThreeMonths) 

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell 

    let cell = tableView.dequeueReusableCell(withIdentifier: "cell", for: indexPath) as! MonthTableViewCell

    switch indexPath.row 
    case 0: cell.nonWorkingAllowance?.text = String()

    

    cell.monthLabel?.text = monthsOfNonWorking[indexPath.row]

    return cell

如何在使用按钮操作计算后在表格视图单元格上显示结果？ 比如我想在tableViewCell上显示数据firstThreeMonths？

【参考方案1】：

只需在按钮操作的末尾添加tableView.reloadData()。

@IBAction func nonWorkingAllowanceCalculate(_ sender: Any) 

var firstThreeMonths :Double
var secondThreeMonths :Double
var LastThreeMonths :Double

let bezdarbienieka_alga = Double(bezd_alga.text!)


if (staza_masiva_lasisana == 0) 

    firstThreeMonths = Double(bezdarbienieka_alga! / 2)

    secondThreeMonths = Double(firstThreeMonths / 2)

    LastThreeMonths = Double(bezdarbienieka_alga! / 1.6 - secondThreeMonths)
 

 tableView.reloadData()
