jsonMode 的使用《总体感觉就是看的再多都不如敲一遍收获大》

首先用cocoaPods 导入JSONModel，AFNetworking

请求下来的数据是html格式的

1、首先新建一个MODE，继承自JsonMode

2、根据网络请求的数据，建立模型

{    "status": 200,     "info": "请求成功",     "data": [        {},         {}    ],     "banner": [        {},         {}    ],     "statistics": {        "turnover": "17,454.83",         "profit": "100.21"    },     "server_phone": "400-1234-123"}

Mode里的模型 .h文件

@interface DataMode : JSONModel

@property (nonatomic ,strong) NSString * loanId;

@property (nonatomic ,strong) NSString * loanCategory;

@property (nonatomic ,strong) NSString * status;

@property (nonatomic ,strong) NSString * loanTitle;

@property (nonatomic ,strong) NSString * loanInterestRate;

@property (nonatomic ,strong) NSString * loanDuration;

@property (nonatomic ,strong) NSString * investorCount;

@property (nonatomic ,strong) NSString * biddingProgress;

@end

@interface BannerMode : JSONModel

@property (nonatomic ,strong) NSString * url;

@property (nonatomic ,strong) NSString * htmlUrl;

@property (nonatomic ,strong) NSString * htmlTitle;

@end

@interface statisticsMode :JSONModel

@property (nonatomic ,strong) NSString * turnover;

@property (nonatomic ,strong) NSString * profit;

@end

@interface HomeMode : JSONModel

@property (nonatomic ,assign) int status;

@property (nonatomic ,strong) NSString * info;

@property (nonatomic ,strong) NSArray <DataMode *> * data;//要和json里的kye值对应

@property (nonatomic ,strong) NSArray <BannerMode*> * banner;//要和json里的kye值对应

@property (nonatomic ,strong) statisticsMode * statistics;//要和json里的kye值对应

@property (nonatomic ,strong) NSString * server_phone;

@end

Mode .m文件

@implementation HomeMode

+ (BOOL)propertyIsOptional:(NSString *)propertyName

{

returnYES;

}

@end

@implementation DataMode

+ (BOOL)propertyIsOptional:(NSString *)propertyName

{

returnYES;

}

@end

@implementation BannerMode

+ (BOOL)propertyIsOptional:(NSString *)propertyName

{

returnYES;

}

@end

@implementation statisticsMode

+ (BOOL)propertyIsOptional:(NSString *)propertyName

{

returnYES;

}

@end

这个方法的作用请求的数据mode里没有该对象，不会报错

具体使用

[manager GET:strparameters:nilprogress:nilsuccess:^(NSURLSessionDataTask *_Nonnull task, id _Nullable responseObject) {

HomeMode * homeData = [[HomeModealloc]initWithData:responseObjecterror:nil];

BannerMode * banner = homeData.banner[0];

NSLog(@"%@",((NSDictionary * )banner)[@"url"]);

} failure:^(NSURLSessionDataTask *_Nullable task, NSError *_Nonnull error) {

NSLog(@"%@",error);

}];

学习中遇到的问题：

1、jsonMode里的嵌套模型，

@interface HomeMode : JSONModel

@property (nonatomic ,assign) int status;

@property (nonatomic ,strong) NSString * info;

@property (nonatomic ,strong) NSArray <DataMode *> * data;//要和json里的key值对应

@property (nonatomic ,strong) NSArray <BannerMode*> * banner;//要和json里的key值对应

@property (nonatomic ,strong) statisticsMode * statistics;//要和json里的key值对应

@property (nonatomic ,strong) NSString * server_phone;

@end

要和 json里的key对应。
