好吧，嗨，我正在使用 moyamapper，我尝试过不同的库，但我发现所有库都存在相同的问题，我无法理解我哪里出错了。现在我有一种方法可以在 moya 结果中得到结果，直到她都很好

我在这里使用pod 'MoyaModelMapper'

func getCategories() {
    let APIProviderClosure = APIHelper.getAPIProvider()
    let provider = MoyaProvider<APIType>(endpointClosure:APIProviderClosure, plugins: [NetworkLoggerPlugin(verbose: true)])
provider.request(APIType.categories()) { (result) in
    if case .success(let response) = result {
      do {

        let repos1 = try response.map(to: [activities.self],fromKey: "data.activities")   //<---ERROR HERE
        let repos = try response.mapString(atKeyPath: "status")   
        Logger.log(repos)
        Logger.log(repos1)
      } catch MoyaError.jsonMapping(let error) {
        Logger.log(msgTitle: "ERROR-->", msg: error)
      } catch {
        print(":(")
      }
    }
  }

}

我在这里得到了结果，它很好，但是当我尝试将结果映射到一个对象时，我得到一个错误，如果我将字符串映射为一个简单的状态字符串，那么它可以工作，但是对于对象它会抛出错误，我无法理解这里有什么问题。

我试过了

Moya-ModelMapper

和许多其他映射器库，但我遇到了同样的问题。下面是我试图解析为对象的 json

{

            ],
            "id":7,
            "title":"Meeting"
        },
        {
            "sub_categories":[

            "id":6,

        {

            "id":41,
            "title":"Project Review"
        },
        {
            "sub_categories":[
            ],
            "id":52,
            "title":"Sales Follow-up"
        },
        {
            "sub_categories":[
            ],
            "id":2,
            "title":"Scrum Meeting"
        },
        {
            "sub_categories":[
            ],
            "id":4,
            "title":"Seminar"
        },
        {
            "sub_categories":[
            ],
            "id":43,
            "title":"Study / Self Learning"
        },
        {
            "sub_categories":[
            ],
            "id":5,
            "title":"Tea Break"
        }
    ]
}

}

我想将其解析为的模型是

class Activities: Mappable {
  var id:String?
  var title:String?
  var isProject:String?
  var subCategories:[Activities]?

  //Default Init
  init(){}

  public required init(map: Mapper) throws {
    try id = map.from("id")
    try title = map.from("title")
    try isProject = map.from("is_project")
    try subCategories = map.from("sub_categories")
  }

  func hasSubCategories() -> Bool {
    if((self.subCategories?.count)! > 0){
      return true
    }else{
      return false
    }
  }

  func getSubCategories() -> [Activities] {
    return self.subCategories!
  }
 }

提前致谢！！！
