json - 如何使用 Swift Object Mapper 映射嵌套对象数组？

Question

我正在尝试使用 Object Mapper 映射一组对象

到目前为止我有这段代码，但我的映射没有成功

do {
    if let data = data,  let sectorData =  Mapper<SubSectorsModel>().mapArrayOfArrays(JSONObject: try JSONSerialization.data(withJSONObject: data, options: [])) {
        completionHandler(sectorData,(response as! HTTPURLResponse), error)
        print("SectionData Received Successfully")
    }
} catch {
    completionHandler(nil,(response as! HTTPURLResponse), error)
    print("Error parsing json get sector data: ", error.localizedDescription)
}

我的Json数据如下:

[
    {
        "SECTOR_NAME": "MANUFACTURERS",
        "ID": "8",
        "SECTOR": [
            {

如果您只想发送 completionHandler，请使用以下代码:

struct MyJsonStruct : Decodable {
    struct SectorStruct : Decodable {
        var ID : String
        var NAME : String
    }
    var SECTOR_NAME : String
    var ID : String
    var SECTOR : [SectorStruct]
}


func handle(_ data : Data ) {
    do {
        let sectorData = try JSONDecoder().decode(MyJsonStruct.self, from: data) as MyJsonStruct

        let yourArray = sectorData.SECTOR // if you need an array result

        completionHandler(sectorData,(response as! HTTPURLResponse), error)
        print("SectionData Received Successfully")
    } catch {
        completionHandler(nil,(response as! HTTPURLResponse), error)
        print("Error parsing json get sector data: ", error.localizedDescription)
    }

}
