ios - 如果对象包含基于 key 的重复名称，则对json对象进行分组？

我们有如下数组的json对象:

[{
    "CompanyCode": "1",
    "MachineCode": null,
    "MachineName": null,
    "NoOfMeters": null,
    "ScheduleNo": "12028",
    "ScheduleDate": "17/2/2018 12:00:00 AM",
    "ScheduleUser": "sales",
    "CustomerCode": "0022100007",
    "DeliveryCode": "0",
    "SortOrder": "1",
    "JobRefNo": "",
    "CustomerName": "COLD STORAGE SUPERMARKETS ",
    "CustAddress1": "GIANT COMPLEX",
    "OutletName": "",
    "OutAddress1": "",
    "IsJobClosed": ""
}, {
    "CompanyCode": "1",
    "MachineCode": null,
    "MachineName": null,
    "NoOfMeters": null,
    "ScheduleNo": "12029",
    "ScheduleDate": "17/2/2018 12:00:00 AM",
    "ScheduleUser": "sales",
    "CustomerCode": "0022100008",
    "DeliveryCode": "0",
    "SortOrder": "1",
    "JobRefNo": "",
    "CustomerName": "COLD STORAGE WH - 21 TAMPINES ",
    "CustAddress1": "GIANT COMPLEX",
    "OutletName": "",
    "OutAddress1": "",
    "IsJobClosed": ""
}, {
    "CompanyCode": "1",
    "MachineCode": null,
    "MachineName": null,
    "NoOfMeters": null,
    "ScheduleNo": "12027",
    "ScheduleDate": "17/2/2018 12:00:00 AM",
    "ScheduleUser": "winapp",
    "CustomerCode": "0022100003",
    "DeliveryCode": "0",
    "SortOrder": "1",
    "JobRefNo": "",
    "CustomerName": "AVENZA PTE LTD ",
    "CustAddress1": "83 CLEMENCEAU AVE",
    "OutletName": "",
    "OutAddress1": "",
    "IsJobClosed": ""
}, {
    "CompanyCode": "1",
    "MachineCode": null,
    "MachineName": null,
    "NoOfMeters": null,
    "ScheduleNo": "12025",
    "ScheduleDate": "17/2/2018 12:00:00 AM",
    "ScheduleUser": "winapp",
    "CustomerCode": "0022100001",
    "DeliveryCode": "0",
    "SortOrder": "1",
    "JobRefNo": "",
    "CustomerName": "CASH ON DELIVERY (TO) ",
    "CustAddress1": "CASH ON DELIVERY",
    "OutletName": "",
    "OutAddress1": "",
    "IsJobClosed": ""
}, {
    "CompanyCode": "1",
    "MachineCode": null,
    "MachineName": null,
    "NoOfMeters": null,
    "ScheduleNo": "12026",
    "ScheduleDate": "17/2/2018 12:00:00 AM",
    "ScheduleUser": "winapp",
    "CustomerCode": "0022100002",
    "DeliveryCode": "0",
    "SortOrder": "1",
    "JobRefNo": "",
    "CustomerName": "DESPATCH - MT ",
    "CustAddress1": "DESPATCH",
    "OutletName": "",
    "OutAddress1": "",
    "IsJobClosed": ""
}]

我们希望根据 ScheduleUser 键(如一节)对这个数组进行分组。

[
  "Sales":[
            {

            }
            {

            }

           ]
  "winapp":[
            {

                }
            {

                }

            {

            }

            ]
  ]

我们已经研究了关于快速4分组Here

但是他们给定了字符串数组，我们不知道要使用json值。
如果有其他方法，请给我们解决方案。我们引用了以下Link

我们无法理解这一点。

从本地获取价值

if let path = Bundle.main.path(forResource: "salesorder", ofType: "json") {
        do {
            let data = try Data(contentsOf: URL(fileURLWithPath: path), options: .alwaysMapped)
            do{
                let json =  try JSONSerialization.jsonObject(with: data, options: .allowFragments)
                let jsonDictionary =  json as? [[String:Any]]

                print(jsonDictionary!)

            }catch let error{
                print(error.localizedDescription)
            }
        } catch let error {
            print(error.localizedDescription)
        }
    } else {
        print("Invalid filename/path.")
    }

提前致谢..

最佳答案

更好
使用分组方式

if let path = Bundle.main.path(forResource: "salesorder", ofType: "json") {
        do {
            let data = try Data(contentsOf: URL(fileURLWithPath: path), options: .alwaysMapped)
            do{
                let json =  try JSONSerialization.jsonObject(with: data, options: .allowFragments)
                if let jsonDictionary =  json as? [[String:Any]]{

                var grouped2 : [String:[[String:Any]]] = Dictionary(grouping: jsonDictionary, by: {$0["ScheduleUser"] as! String})
                debugPrint(grouped2)
                print(jsonDictionary)
                }

            }catch let error{
                print(error.localizedDescription)
            }
        } catch let error {
            print(error.localizedDescription)
        }
    } else {
        print("Invalid filename/path.")
    }

手动方式

if let path = Bundle.main.path(forResource: "salesorder", ofType: "json") {
            do {
                let data = try Data(contentsOf: URL(fileURLWithPath: path), options: .alwaysMapped)
                do{
                    let json =  try JSONSerialization.jsonObject(with: data, options: .allowFragments)
                    if let jsonDictionary =  json as? [[String:Any]]{

                        var grouped : [String:[[String:Any]]] = [:]
                        for dict in jsonDictionary {
                            let value = dict["ScheduleUser"] as! String
                            if(grouped[dict["ScheduleUser"] as! String] == nil){
                                grouped[value] = [dict]
                            }else{
                                grouped[value]?.append(dict)
                            }
                        }
                        debugPrint(grouped)
                    print(jsonDictionary)
                    }

                }catch let error{
                    print(error.localizedDescription)
                }
            } catch let error {
                print(error.localizedDescription)
            }
        } else {
            print("Invalid filename/path.")
        }
