这是我的模型类，我通过它在我的模型类中传递 json，

    import ObjectMapper

class OpenHouseModel: Mappable {

    var totalPages : Int?
    var pageNumber : Int?
    var numberOfElements : Int?
    var totalRecords : Int?
    var propertyData : [PropertyData]?

    required init?(map: Map) {

    }

    func mapping(map: Map) {

        totalPages <- map["totalPages"]
        pageNumber <- map["pageNumber"]
        numberOfElements <- map["numberOfElements"]
        totalRecords <- map["totalRecords"]
        propertyData <- map["data"]
    }
}

class PropertyData: Mappable {

    var buyerProcessId : Int?
    var bidReferenceNo : String?
    var processType : String?
    var chiraghProperty : ChiraghProperty?
    var images : [PropertyImages]?

    required init?(map: Map) {

    }

    func mapping(map: Map) {

        processType <- map["processType"]
        buyerProcessId <- map["buyerProcessId"]
        buyerProcessId <- map["bidReferenceNo"]
        chiraghProperty <- map["chiraghproperty"]
        images <- map["images"]
    }
}


class ChiraghProperty: Mappable {

    var propertyId : Int?
    var propertyTitle : String?
    var propertyDescription : String?
    var sizePerSqft : Double?
    var address : String?
    var propertyReferenceNo : String?
    var pricePerSqft : Double?
    var noOfBedrooms : Int?
    var noOfBaths : Int?
    var typeArea : String?
    var projectName : String?
    var presentUse : String?
    var propertyType : String?
    var dateReceived : String?
    var areaUnit : String?
    var status : String?
    var netArea : String?
    var grossArea : String?
    var valuationReportCopy : String?
    var valuationReportDocument: String?
    var brokerageReportCopy: String?
    var spaDocument : String?
    var formAUpload : String?

    required init?(map: Map) {

    }

    func mapping(map: Map) {

        propertyId <- map["propertyId"]
        propertyTitle <- map["propertyTitle"]
        propertyDescription <- map["propertyDescription"]
        sizePerSqft <- map["sizePerSqft"]
        address <- map["address"]
        propertyReferenceNo <- map["propertyReferenceNo"]
        pricePerSqft <- map["pricePerSqft"]
        noOfBedrooms <- map["noOfBedrooms"]
        noOfBaths <- map["noOfBaths"]
        typeArea <- map["typeArea"]
        projectName <- map["projectName"]
        propertyType <- map["propertyType"]
        dateReceived <- map["dateReceived"]
        areaUnit <- map["areaUnit"]
        status <- map["status"]
        netArea <- map["netArea"]
        valuationReportCopy <- map["valuationReportCopy"]
        valuationReportDocument <- map["valuationReportDocument"]
        brokerageReportCopy <- map["brokerageReportCopy"]
        spaDocument <- map["spaDocument"]
        formAUpload <- map["formAUpload"]

    }
}


class PropertyImages: Mappable {

    var imageUrl : String?
    var imageName : String?

    required init?(map: Map) {

    }

    func mapping(map: Map) {

        imageUrl <- map["imageUrl"]
        imageName <- map["imageName"]
    }
}

现在，当我运行代码并获取值时，buyerProcessId 键为 nil。其他值都很好，我不知道为什么它不显示 chiraghuser 上方这些键的值。

Answer 1

看起来您的问题出在 PropertyData 中，因为您似乎正在将 bidReferenceNo 映射到 buyerProcessId。这就是您得到 nil 的原因。

class PropertyData: Mappable {

    var buyerProcessId : Int?
    var bidReferenceNo : String?
    var processType : String?
    var chiraghProperty : ChiraghProperty?
    var images : [PropertyImages]?

    required init?(map: Map) {

    }

    func mapping(map: Map) {

        processType <- map["processType"]
        buyerProcessId <- map["buyerProcessId"]
        buyerProcessId <- map["bidReferenceNo"] // this seems like it is wrong and should be bidReferenceNo
        chiraghProperty <- map["chiraghproperty"]
        images <- map["images"]
    }
}
