从 Swift 中的 Json 响应中填充 TableSection

Question

如何使用此 JSON 响应填充 TableSection。

我已经实现了类似下拉菜单的设计，并在其中有一个原型单元格，其中并排有两个标签。 下面是我设计的结构

StudentDetailsS​​ection V（按钮）

父亲的详细信息第 V 部分（按钮）

Mother'sDetailsS​​ection V（按钮）

我还附上了我的设计截图

我的 JSON 响应在结构中。

{
    "Student_Details":
    [

如何从此 jsonresponse 中获取数据并填写特定部分。希望得到帮助。提前致谢。

Answer 1

假设您有 3 个静态部分：

1) 声明常量是一个好习惯。

let SEC_STUDENT = 0
let SEC_FATHER  = 1
let SEC_MOTHER  = 2

2) 从响应中获取数组

enum Student_Key : String
{
    case ID = "Student_ID"
    case FirstName = "FirstName"
    case LastName = "LastName"
    //Define all keys so on
}

enum Father_Key : String
{
    case Name = "Father_Name"
    case Mobile = "Father_Mobile"
    //Define all keys so on
}

enum Mother_Key : String
{
    case Name = "Mother_Name"
    case Mobile = "Mother_Mobile"
    //Define all keys so on
}


//Define global 

var arrStudent : Array<[String:String]> = []
var arrMother : Array<[String:String]> = []
var arrFather : Array<[String:String]> = []

//Add new method to parse response

func parseData(response : [String:Any]) {


    let arrayData = response["Student_Details"] as! [Any]

    //You can load only one record in your current way.
    let studentData = arrayData[0] as! [String:Any]

    arrStudent.append(["key":Student_Key.ID.rawValue ,
                       "value" : String(describing: studentData[Student_Key.ID.rawValue])])
    arrStudent.append(["key":Student_Key.FirstName.rawValue,
                       "value": String(describing: studentData[Student_Key.FirstName.rawValue])])
    arrStudent.append(["key":Student_Key.LastName.rawValue,
                       "value": String(describing: studentData[Student_Key.LastName.rawValue])])
    //You have to add all keys mannualy

    arrMother.append(["key":Father_Key.Name.rawValue,
                      "value": String(describing: studentData[Father_Key.Name.rawValue])])
    arrMother.append(["key":Father_Key.Mobile.rawValue,
                      "value": String(describing: studentData[Father_Key.Mobile.rawValue])])

    arrFather.append(["key":Mother_Key.Name.rawValue,
                      "value": String(describing: studentData[Mother_Key.Name.rawValue])])
    arrFather.append(["key":Mother_Key.Mobile.rawValue,
                      "value": String(describing: studentData[Mother_Key.Mobile.rawValue])])

    yourTable.reloadData()
}

3) 返回部分，你已经实现了。

4) 返回行数

func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {

    if indexPath.section == SEC_STUDENT
    {
        return arrStudent.count
    }
    else if indexPath.Section ==  SEC_FATHER
    {
        return arrFather.count
    }
    else if indexPath.Section == SEC_MOTHER
    {
        return arrMother.count
    }
    else {
        return 0
    }
}

5) 索引称重传感器

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


    let cell = tableView.dequeueReusableCell(withIdentifier: "YourCellIdentifier") as! YourCell

    let dictData :  [String:Any]

    if indexPath.section == SEC_STUDENT
    {
        dictData = arrStudent[indexPath.row] as! [String:Any]

    }
    else if indexPath.Section ==  SEC_FATHER
    {
        dictData = arrFather[indexPath.row] as! [String:Any]
    }
    else if indexPath.Section == SEC_MOTHER
    {
        dictData = arrayData[indexPath.row] as! [String:Any]
    }

    cell.lblKey =  data["key"]
    cell.lblValue = data["value"]
    return cell
}

** 备注

1) 这可能是您的要求，但这不是处理和显示 json 的正确方法。

2) 目前只能显示在学生记录上，应该是学生的详情页。

3) 我只是输入代码来展示实现目标的方法。你必须在你的代码中处理事情。
