ios - 在 ObjectMapper 中调用 super 方法的问题

Question

尝试将 ObjectMapper 语法转换为 Swift 3.0:

class CustomJsonResponse: Mappable {

    var status: String?
    var response: String?
    var errorCode: CustomErrorCode?

    init() {

    }

    required init?(map: Map) {

    }

    func mapping(map: Map) {
        status <- map["status"]
        response <- map["response"]
        errorCode <- (map["error_code"], CustomErrorCodeTransform())
    }
}

class CustomChallengesResponse: CustomJsonResponse {

    var challenges: [CustomChallenge]?

    required init?(_ map: Map) {
        super.init(map: map)
    }

    override func mapping(map: Map) {
        super.mapping(map: map)

        challenges <- map["data.questions"]
    }
}

我在以下位置遇到错误:

required init?(_ map: Map) {
            super.init(map: map)
        }

“必需的初始化程序必须由 CustomJsonResponse 的子类提供”

我在这里做错了什么？对此的任何指示都会很棒。谢谢!

我想你错过了:

init() {
    super.init()
}
