YYModel使用詳解

根據需求、後臺返回以下數據、須要解析爲model類、方便操做數據。

NSDictionary *returnDic = @{
                                @"birthPlace":@"寧夏固原市彭陽縣草廟鄉",

此數據包括四大模塊:

1.基本信息-字符串

2.我的信息-personalMessage（字典）

3.小孩父親資料-babyFatherInfo（字典）

4.歷史懷孕詳情-pregnancyHistorys（字典包含一個大的數組pregnancyHistory，數組包含n個字典，每一個字典包含基本信息以及n個胎數）

接下來咱們構建model類:

#import <Foundation/Foundation.h>
@class YYModel_PersonalModel,PersonalMessageModel,BabyFatherInfoModel,PregnancyHistorys,BabyInfos,BabyInfoModel;
NS_ASSUME_NONNULL_BEGIN

@interface YYModel_PersonalModel : NSObject

@property(nonatomic,copy) NSString *marryStatus;

使用YYModel解析以下

首先咱們解析除pregnancyHistorys意外全部數據

在model .m文件使用以下方法

// 若是實現了該方法，則處理過程當中會忽略該列表內的全部屬性-黑名單
+ (NSArray *)modelPropertyBlacklist {
    return @[@"pregnancyHistorys"];
}
複製代碼

因爲基本信息出現了id關鍵字、model .m文件中特做以下處理：

// 當後臺返回系統關鍵字時、屬性數據映射，用來定義多樣化數據時轉換聲明
+ (NSDictionary *)modelCustomPropertyMapper {
    return @{
             @"personId":@"id",
             };
}
複製代碼

執行了此方法，就能夠將id轉變爲personID。

解析過程以下：（註明了YYModel經常使用的方法、這裏不一一解釋）

NSDictionary *dictionary = [[YYModelJsonData shareInstance]dataDictionary];
//字典轉模型 + (nullable instancetype)yy_modelWithDictionary:(NSDictionary *)dictionary
YYModel_PersonalModel *model = [YYModel_PersonalModel yy_modelWithDictionary:dictionary];
NSLog(@"出生地：%@、教育水平：%@、personID：%@、我的信息-結婚年齡：%@、小孩父親：%@",model.birthPlace,model.education,model.personId,model.personalMessage.marryAge,model.babyFatherInfo.bFatherName);
    
//模型轉json字符串 yy_modelToJSONString
NSString *json = [model yy_modelToJSONString];
NSLog(@"json:%@",json);
    
// 模型轉NSObject yy_modelToJSONObject
NSDictionary *returnDic = [model yy_modelToJSONObject];
NSLog(@"returnValue:%@",returnDic);
    
// 模型轉NSData yy_modelToJSONData
NSData *dataJson = [model yy_modelToJSONData];
NSLog(@"dataJson:%@",dataJson);

另外，YYModel還提供了白名單：

若是實現了該方法，則處理過程當中不會處理該列表外的屬性-白名單
假如只須要解析我的信息時，返回personalMessage便可
+ (NSArray *)modelPropertyWhitelist {
    return @[@"personalMessage"];
}
複製代碼

經過以上解析過程、咱們基本掌握了YYModel常見的方法，解析之後，也能拿到本身想要的數據。具體處理過程還須要結合UI需求。
