如何在Swift 3中将数据附加到来自服务器响应的字典中？

Question

在这里，我收到服务器数据的响应，但是在这里，我需要显示如下运输方法部分中的图像所示，在此承运人标题中将包含子方法，在该子方法中，该子方法需要按节中的行数显示，并显示节标题承运人标题将被命名，并且此处的方法标题需要从具有相同名称的特定运营商标题中追加，任何人都可以帮助我实现该方法吗？

我已经尝试过的代码是

var doubleRemoving : [String:Any] = [:]

do
            {
                let array = try JSONSerialization.jsonObject(with: data, options: []) as? [[String : Any]]
                self.responseData = array!
                print(self.responseData)
            }
            catch let error
            {
                print("json error:", error)
            }
            for item in self.responseData {
                let dict = item
                let array = dict["carrier_title"]
                self.keyString.append(array as! String)
                self.doubleRemoving.updateValue(0, forKey: array as! String)
                print(self.doubleRemoving)
            }
            for item in self.responseData{
                if self.doubleRemoving.keys.contains(item["carrier_title"] as! String) {
                    self.doubleRemoving.updateValue(item["method_title"]!, forKey: item["carrier_title"] as! String)
                }
                print(self.doubleRemoving)
            }
            let status = (response as! HTTPURLResponse).statusCode
            self.keyStatusCode = status
            print(status)
        }
        task.resume()
    }

来自服务器的Json响应是

[
      {
        "carrier_code": "flatrate",
        "method_code": "flatrate",
        "carrier_title": "Flat Rate",
        "method_title": "Fixed",
        "amount": 0,
        "base_amount": 0,
        "available": true,
        "error_message": "",
        "price_excl_tax": 0,
        "price_incl_tax": 0
      },
      {
        "carrier_code": "tablerate",
        "method_code": "bestway",
        "carrier_title": "Best Way",
        "method_title": "Table Rate",
        "amount": 0,
        "base_amount": 0,
        "available": true,
        "error_message": "",
        "price_excl_tax": 0,
        "price_incl_tax": 0
      },
      {
        "carrier_code": "tablerate",
        "method_code": "bestway",
        "carrier_title": "Best Way",
        "method_title": "Worldwide Expedited",
        "amount": 0,
        "base_amount": 0,
        "available": true,
        "error_message": "",
        "price_excl_tax": 0,
        "price_incl_tax": 0
      },
      {
        "carrier_code": "tablerate",
        "method_code": "bestway",
        "carrier_title": "Best Way",
        "method_title": "Worldwide Express Saver",
        "amount": 0,
        "base_amount": 0,
        "available": true,
        "error_message": "",
        "price_excl_tax": 0,
        "price_incl_tax": 0
      }
]

Answer 1

你可以做这样的事情

var finalDict = [String: [String]]()
let array = try JSONSerialization.jsonObject(with: getData()!, options: []) as! NSArray
for item in array {
    let dict = item as! NSDictionary
    let carrierTitle = dict["carrier_title"] as! String
    let methodTitle = dict["method_title"] as! String
    if finalDict[carrierTitle] == nil {
        finalDict[carrierTitle] = [String]()
    }
    finalDict[carrierTitle]!.append(methodTitle)
}

输出量

["Flat Rate": ["Fixed"], "Best Way": ["Table Rate", "Worldwide Expedited", "Worldwide Express Saver"]]

更新

要获取所有值的计数，请执行以下操作

var count = 0
for (key, value) in finalDict {
    count += value.count
}
