【问题描述】：

我收到一个 JSON 作为对使用 AFNetworking 的 POST 方法的响应。我需要将 JSON 映射到自定义类并创建一个包含来自 JSON 的值的对象。

JSON 字符串

{
branch =     {
    address = "";
    email = "";
    globalId = 174;
    id = 0;
    mobile = 9846147442;
    name = "Sathish Clininc Branch1";
    netMdId = 132;
    numberOfDevices = 0;
    organisationName = "<null>";
    passPhrase =         (
    );
    phone = 04872279166;
    status = active;
};
error = "<null>";
netmd =     {
    globalId = 132;
    headOfficeAddress = "";
    headOfficeEmail = "sreejith@gmail.com";
    headOfficeMobile = "";
    headOfficeName = Koorkenchery;
    headOfficePhone = "";
    id = 0;
    name = "Sathish Clinic";
    ownerAddress = "";
    ownerEmail = "sreejith@gmail.com";
    ownerFirstName = Sathish;
    ownerLastName = Chandran;
    ownerMobile = "";
    ownerPhone = "";
    password = "aW8oFWDMOJUrIV3l7R7hqQ==";
    status = active;
    userName = sathish;
    userType = owner;
};
primary = 1;
retrieveAppointments =     (
);
retrieveDoctorsList =     (
);
retrievePatients =     (
);
retrieveScheduleList =     (
);
success = 1;
user =     (
);    }

自定义类

#import <Foundation/Foundation.h>
#import "ErrorDTO.h"
#import "NetMdBranchDTO.h"
#import "NetMdDTO.h"
@interface NetMdActivationResponseDTO : NSObject
@property (nonatomic, strong)ErrorDTO* error;
@property (nonatomic, assign) BOOL success;
@property (nonatomic, strong) NetMdBranchDTO* branch;
@property (nonatomic, strong) NetMdDTO* netmd;
@property (nonatomic, strong) NSArray* user;
@property (nonatomic, strong) NSArray* retrieveDoctorsList;
@property (nonatomic, strong) NSArray* retrievePatients;
@property (nonatomic, strong) NSArray* retrieveScheduleList;
@property (nonatomic, strong) NSArray* retrieveAppointments;
@property (nonatomic, assign) BOOL primary;

@end

【解决方案1】：

您可以使用Mantle 提升您的价值对象。维护所有转换会更容易。

【解决方案2】：

如果您的 JSON 键与您的自定义类的属性相匹配，那么这很简单：

使用NSJSONSerialization 类将您的 JSON 数据反序列化为 NSDictionary。
使用[object setValuesForKeysWithDictionary:deserializedDictionary] 填充您的自定义对象属性

如果键不匹配，则设置object.user = deserializedDictionary[@"userName"]等属性

另一种选择是允许自定义对象接受各种键并通过覆盖-setValue:ForKey:在对象内进行映射

【解决方案3】：

使用JSON Accelerator 生成你的类添加到代码执行

如果你想自己处理

{} : Represents object/Dictionary
[] : Represents array

深入写下每一个细节并得到你需要的东西
