显示来自JSON数据的tableviewcell内的标签

如何解决显示来自JSON数据的tableviewcell内的标签

我正在使用Swift创建应用，我想在UITableViewCell内使用JSON解析显示一些标签，这是我想在我的应用中做的屏幕截图

Here is the screen shot i want to do like this

如屏幕截图Flat1所示，Flat2是我要在UITableVieCell中显示的标签，并用于显示我在下面使用的标签

This is the TagListView Which i have used

这是我的JSON数据，来自WebService

{
  "success": "1","data": [
    {
      "fk_project_surveyors_id": "1","number": 1,"created_date": "2020-04-17 10:09:57","sub_cores": [
        {
          "sub_cores_title": "Flat 1"
        }
      ],"signature": "img_sFZuFpUd011587136197.png","name": "Sean Clancy","inspections_id": "4","fk_user_id": "1","fk_cores_id": "12","survey_date": "2020-04-12"
    },{
      "fk_project_surveyors_id": "1","number": 2,"created_date": "2020-04-29 12:55:45","sub_cores": [
        {
          "sub_cores_title": "Flat 1"
        },{
          "sub_cores_title": "Flat 2"
        }
      ],"signature": "img_Ptw0bvSGfR1588182945.png","inspections_id": "6","number": 3,"created_date": "2020-05-06 06:08:11","signature": "img_FSUTzxT4221588763291.png","inspections_id": "7","number": 4,"created_date": "2020-06-15 04:25:16","signature": "img_EVqcz58zN11592213116.png","inspections_id": "8","number": 5,"created_date": "2020-06-21 11:04:56","signature": "img_3ySNyhAjYd1592755496.png","name": "ron","inspections_id": "10","number": 6,"created_date": "2020-06-21 11:05:44","signature": "img_ILSykgAIW71592755544.png","name": "ron2","inspections_id": "11","survey_date": "2020-04-12"
    }
  ],"message": ""
}

正如您在JSON数据中看到的那样，每个项目都具有sub_cores数组，因此我想从sub_cores_title中显示在TagListView内部的UITableViewCell

这是我用来解析JSON之上的模型结构

public struct HistoryModel{
    var fk_user_id: String?
    var signature: String?
    var fk_cores_id: String?
    var name: String?
    var inspections_id: String?
    var fk_project_surveyors_id: String?
    var created_date: String?
    var number: String?
    var survey_date: String?
    var sub_cores: [SubCoreModelData]
    
    public init(fk_user_id: String,signature: String,fk_cores_id: String,name: String,inspections_id: String,fk_project_surveyors_id: String,created_date: String,number: String,survey_date: String,sub_cores:[SubCoreModelData]) {
        self.fk_user_id = fk_user_id
        self.signature = signature
        self.fk_cores_id = fk_cores_id
        self.name = name
        self.inspections_id = inspections_id
        self.fk_project_surveyors_id = fk_project_surveyors_id
        self.created_date = created_date
        self.number = number
        self.survey_date = survey_date
        self.sub_cores = sub_cores
    }
}

public struct SubCoreModelData{
    var sub_core_title: String?
    
    public init(sub_core_title: String?) {
        self.sub_core_title = sub_core_title
    }
}

这是我的代码API调用函数，我从中将数据存储到数组

var historyData = HistoryModel

func historyAPI(){
        guard let uid = UserDefaults.standard.string(forKey: "uid") else { return }
        guard let accessToken = UserDefaults.standard.string(forKey: "accToken") else { return }
        guard let projectid = UserDefaults.standard.string(forKey: "propSurID") else { return }
        
        let params = ["user_id": uid,"access_token": accessToken,"project_surveyors_id": projectid,"cores_id": self.coreid]
        print(params)
        showHud(view: self.view,message: "Please Wait")
        AF.request(previousinspectionlist,method: .post,parameters: params).responseJSON(completionHandler: {(response) in
            switch response.result{
            case.success(let value):
                let json  = JSON(value)
                print(json)
                let data = json["data"]
                if data == []{
    
                }else{
                    self.historyData.removeAll()
                    for cat in data{
                        let fk_user_id = cat.1["fk_user_id"].stringValue
                        let name = cat.1["name"].stringValue
                        let signature = cat.1["signature"].stringValue
                        let fk_cores_id = cat.1["fk_cores_id"].stringValue
                        let inspections_id = cat.1["inspections_id"].stringValue
                        let fk_project_surveyors_id = cat.1["fk_project_surveyors_id"].stringValue
                        let created_date = cat.1["created_date"].stringValue
                        let number = cat.1["number"].stringValue
                        let survey_date = cat.1["survey_date"].stringValue


                        var arrOfItems = [SubCoreModelData]()
                        for ser in cat.1["sub_cores"] {
                            let subcore = SubCoreModelData(sub_core_title: ser.1["sub_cores_title"].stringValue)
                            arrOfItems.append(subcore)
                        }
                        self.historyData.append(HistoryModel(fk_user_id: fk_user_id,signature: signature,fk_cores_id: fk_cores_id,name: name,inspections_id: inspections_id,fk_project_surveyors_id: fk_project_surveyors_id,created_date: created_date,number: number,survey_date: survey_date,sub_cores: arrOfItems,collapsed: false))
                    }
                }
                self.tblListView.reloadData()
                dismissHud()
            case.failure(let error):
                basicErrorAlertWith(title: "Error",message: error.localizedDescription,controller: self)
                dismissHud()
            }
        })
    }

但是使用此代码，我在表视图中获取重复数据，所以任何人都可以告诉我如何为具有Sub Core标题的每一行设置标签，为此请帮我

TableviewDelegate和数据源代码

func numberOfSections(in tableView: UITableView) -> Int {
    return self.historyData.count
}
func tableView(_ tableView: UITableView,numberOfRowsInSection section: Int) -> Int {
    let items = self.historyData[section].sub_cores
    return items.count
}
func tableView(_ tableView: UITableView,cellForRowAt indexPath: IndexPath) -> UITableViewCell {
    let cell = tableView.dequeueReusableCell(withIdentifier: "Cell") as! InspectionHistoryTableViewCell
    cell.lblName.text = historyData[indexPath.row].name
    if let number = historyData[indexPath.row].number{
        print(number)
        cell.lblNumber.text = "#\(number)"
    }
    cell.lblSurveydate.text = historyData[indexPath.row].survey_date
    let items = self.historyData[indexPath.section].sub_cores
    let item = items[indexPath.row]
    if let subcore = item.sub_core_title{
        cell.tagList.addTag(subcore)
    }
    cell.selectionStyle = .none
    return cell
}

解决方法

似乎您在混淆数据模型。对于historyData中的每个条目，您似乎都有一个小节；对于该历史数据中的每个sub_cores，看起来都想要一行。

但是您真正想要的只是一个带有historyData.count行的部分。

在cellForRowAt:中，您将同时访问具有行索引和节索引的历史数据数组，这将导致数据混合，并且很可能很快崩溃。

因此，要更正cellForRowAt:，您只需访问每个行索引的历史数据，然后声明并使用所有sub_core填充标签视图。

这应该有效：

func numberOfSections(in tableView: UITableView) -> Int {
    return 1
}
func tableView(_ tableView: UITableView,numberOfRowsInSection section: Int) -> Int {
    return self.historyData.count
}

func tableView (_ tableView: UITableView,cellForRowAt indexPath: IndexPath) -> UITableViewCell {
    let cell    = tableView.dequeueReusableCell(withIdentifier: "Cell") as! InspectionHistoryTableViewCell
    let row     = indexPath.row
    let data    = historyData[row]
    
    cell.lblName.text = data.name

    if let number = data.number{
        print(number)
        cell.lblNumber.text = "#\(number)"
    }
    
    cell.lblSurveydate.text = data.survey_date
    let items = data.sub_cores
    cell.tagList.removeAllTags()
    for (item in items) {
        cell.tagList.addTag(item.sub_core_title)
    }
    
    cell.selectionStyle = .none
    return cell
}
