使用Alamofire将嵌套数组从JSON数据显示到tableview

标签： ios uitableview swift3 alamofire swifty-json

我已经在tableview中显示了第一个json数据，但是当试图显示内部数组数据的数组数据时，它在表视图中显示空白数据，我已经厌倦了许多方法，有时它会让我看到索引超出范围而且＃39 ;我知道我在哪里出错或忘记编写代码，我能够在表视图中显示费用类数据但不能显示描述数据，或者我是否需要更改我的Ui设计< / p>

这里我有模特课

class Fees {
    var Billno = String()
    var DateOfReciept = String()
    var amount =  String()
    var status = String()
    var recivedDate = String()
    var AmountPaid = String()
    var descriptions = [Description]()


    init(feesJson:JSON) {
        self.Billno = feesJson["RecieptNo"].stringValue
        self.DateOfReciept = feesJson["DateOfReciept"].stringValue
        self.amount = feesJson["dueAmount"].stringValue
        self.status = feesJson["Status"].stringValue
        self.recivedDate = feesJson["recivedDate"].stringValue
        self.AmountPaid = feesJson["AmountPaid"].stringValue

        if let description = feesJson["Description"] as? JSON, let desArray = description.array{
            for desc in desArray{
                let desfees = Description(feedesJson: desc)
                self.descriptions.append(desfees)
            }
        }
    }

}

class Description{
var amountdes =  String()
    var des = String()

    init(feedesJson:JSON){
        self.amountdes = feedesJson["Amount"].stringValue
        self.des = feedesJson["des"].stringValue
    }

}

获取JSON数据的代码

@IBOutlet weak var tableview1: UITableView!
    var fees : [Fees] = []
    var descriptionFe : [Description] = []
func getFees() {
        let defaults = UserDefaults.standard
        let student_id =  defaults.string(forKey: "masteridKey")


        let std_id_String = student_id?.replacingOccurrences(of: "[^0-9 ]", with: "", options: NSString.CompareOptions.regularExpression, range:nil)
        print("numbericpending",std_id_String!)

        let url = NSURL(string: "http://192.168.100.5:84/api/financeApi/getAllFees" + "?ID=" + std_id_String! + "&fromDate=" + "&toDate=")
        var request = URLRequest(url: url! as URL)
        request.httpMethod = "GET"
        request.setValue("application/json", forHTTPHeaderField: "Content-Type")
        Alamofire.request(request).responseJSON(){ response in
            switch response.result{
            case.success(let data):
                print("success",data)

                let myresponse = JSON(data)

                print("tabledata",myresponse)

               // dictdata = myresponse.arrayObject

                for fee in myresponse.array!
                {
                    let feesObj = Fees(feesJson: fee)
                    self.fees.append(feesObj) // here I'am getting array data but not descripition datas and while calling from here to tableview its giving me blank


                }


                for fee in myresponse.array!
                {
                //self.descriptionFe = feesObj.descriptions

                let feesdesc =  Description(feedesJson: fee)

                self.descriptionFe.append(feesdesc)

                }
                self.tableview1.reloadData()
            case.failure(let error):
                print("Not Success",error)
            }

        }


    }

显示到tableview 

func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
       if tableView == tableview1{
        return fees.count
        }else{
        return descriptionFe.count
        }

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

        if tableView == tableview1{
        let cell = tableView.dequeueReusableCell(withIdentifier: "cell", for: indexPath) as! FeesTableViewCell
        let getdata = fees[indexPath.row]
        cell.billno_txt.text = getdata.Billno

            cell.received_date_txt.text = getdata.recivedDate


            cell.status_txt.text = getdata.status
            cell.total_amount_txt.text = getdata.AmountPaid


            cell.date_txt.text = getdata.recivedDate




        return cell

        }
        else{
            let cell = tableView.dequeueReusableCell(withIdentifier: "cell", for: indexPath) as! FeesTableViewCell
//           // let getdatafees = fees[indexPath.row]

          let getdatadesciption = self.descriptionFe[indexPath.row]


            cell.inner_txt1.text = getdatadesciption.des

           // cell.inner_txt2.text = fees[indexPath.row].AmountPaid


            return cell
        }
    }

和JSON api数据格式

[{

        "Status": "D",
        "NAME": "Calvin Patterson",
        "CLASSNO": "1",

我很困惑在tableview中显示该描述，如何显示描述数据的数据??

1 个答案:

答案 0 :(得分：1)

基本上你的代码根本就没有错，但你的想法和实际上有什么数据是主要的冲突，让我告诉你哪里是让你疯狂的确切问题。

清楚地观察你的json反应。我已经在您的数据中编辑了第一条记录，并且没有更改任何内容到第二条记录。在2记录中观察您的描述值。

[{
    "StdID": 95,
    "Status": "D",
    "NAME": "Calvin Patterson",
    "CLASSNO": "1",
    "recivedDate": "2017-06-08T00:00:00",
    "MasterID": "E0017",
    "RecieptNo": 83,
    "DateOfReciept": "2017-06-08T00:00:00",
    "Description": [{"des":"Admission","Amount":1200},{"des":"Due","Amount":0}],
    "AmountPaid": 1200,
    "dueDate": "2017-06-29T00:00:00",
    "dueAmount": 1200,
    "reciever": "Mr. Adminstrator",
    "CLASS_ID": 2021,
    "receivedAmount": 0
},
{
    "StdID": 95,
    "Status": "P",
    "NAME": "Calvin Patterson",
    "CLASSNO": "1",
    "recivedDate": "2017-07-13T00:00:00",
    "MasterID": "E0017",
    "RecieptNo": 1171,
    "DateOfReciept": "2017-07-01T00:00:00",
    "Description": "[{\"des\":\"Admission Fee\",\"Amount\":2000},{\"des\":\"Due\",\"Amount\":1200}]",
    "AmountPaid": 3200,
    "dueDate": "2017-07-30T00:00:00",
    "dueAmount": 3200,
    "reciever": "Mr. Adminstrator",
    "CLASS_ID": 2021,
    "receivedAmount": 0
}]

我在你的第一张唱片中所做的是。

这是实际数据：

 "Description": "[{\"des\":\"Admission\",\"Amount\":1200},{\"des\":\"Due\",\"Amount\":0}]"

删除引号和反斜杠后的结果数据。

"Description": [{"des":"Admission","Amount":1200},{"des":"Due","Amount":0}]

如果您运行此类数据的代码，那么就可以得到您想要的内容。你错的是你从字符串值访问数据，我的意思是

   "Description": "[{\"des\":\"Admission Fee\",\"Amount\":2000},{\"des\":\"Due\",\"Amount\":1200}]",

在上面的数据中，你的描述键的值是一个字符串类型，但你假设它是一个字典数组并访问那些错误的记录 。要解决此问题，请确保您的数据应符合以下格式。

 [{
    "StdID": 95,
    "Status": "D",
    "NAME": "Calvin Patterson",
    "CLASSNO": "1",
    "recivedDate": "2017-06-08T00:00:00",
    "MasterID": "E0017",
    "RecieptNo": 83,
    "DateOfReciept": "2017-06-08T00:00:00",
    "Description": [{"des":"Admission","Amount":1200},{"des":"Due","Amount":0}],
    "AmountPaid": 1200,
    "dueDate": "2017-06-29T00:00:00",
    "dueAmount": 1200,
    "reciever": "Mr. Adminstrator",
    "CLASS_ID": 2021,
    "receivedAmount": 0
},
{
    "StdID": 95,
    "Status": "P",
    "NAME": "Calvin Patterson",
    "CLASSNO": "1",
    "recivedDate": "2017-07-13T00:00:00",
    "MasterID": "E0017",
    "RecieptNo": 1171,
    "DateOfReciept": "2017-07-01T00:00:00",
    "Description": [{"des":"Admission Fee","Amount":2000},{"des":"Due","Amount":1200}],
    "AmountPaid": 3200,
    "dueDate": "2017-07-30T00:00:00",
    "dueAmount": 3200,
    "reciever": "Mr. Adminstrator",
    "CLASS_ID": 2021,
    "receivedAmount": 0
}]
