需要YYModel
- 1、简单新建Xcode工程
- 2、新建pch文件，方便导入公共类头文件
- 3、新建一个
BaseModel类，继承NSObject
@interface BaseModel : NSObject
@property (nonatomic, strong) NSString *message;
@end
最简单的模型
@implementation ViewController
- (void)viewDidLoad {
[super viewDidLoad];
// 假数据
NSDictionary *json = @{
@"message" : @"我是message"
};
// 转模型
BaseModel *model = [BaseModel modelWithJSON:json];
NSLog(@"model.message = %@",model.message);
}
@end

有关键字的模型
.h文件
@interface BaseModel : NSObject
@property (nonatomic, strong) NSString *ID;
@property (nonatomic, strong) NSString *message;
@end
.m文件，进行映射
@implementation BaseModel
+ (NSDictionary *)modelCustomPropertyMapper{
return @{
@"ID" : @"id"
};
}
@end
@implementation ViewController
- (void)viewDidLoad {
[super viewDidLoad];
// 假数据
NSDictionary *json = @{
@"id" : @"123",
@"message" : @"我是message"
};
// 转模型
BaseModel *model = [BaseModel modelWithJSON:json];
NSLog(@"model.message = %@",model.message);
NSLog(@"model.ID = %@",model.ID);
}
@end

模型嵌套模型
- 1、新建一个
AModel类，继承NSObject
- 2、为
AModel新增两个属性分别为title、base
@interface AModel : NSObject
@property (nonatomic, strong) NSString *title;
@property (nonatomic, strong) BaseModel *base;
@end
@implementation ViewController
- (void)viewDidLoad {
[super viewDidLoad];
// 假数据
NSDictionary *json = @{
@"title" : @"我是标题",
@"base" : @{
@"id" : @"123",
@"message" : @"我是message"
}
};
// 转模型
AModel *model = [AModel modelWithJSON:json];
NSLog(@"model.title = %@",model.title);
NSLog(@"model.base = %@",model.base);
NSLog(@"model.base.ID = %@",model.base.ID);
NSLog(@"model.base.message = %@",model.base.message);
}
@end

简单的模型继承
- 1、新建一个
BModel类，继承BaseModel
- 2、为
BModel新增一个属性title，其他属性都从BaseModel继承而来
@interface BModel : BaseModel
@property (nonatomic, strong) NSString *title;
@end
- (void)viewDidLoad {
[super viewDidLoad];
// 假数据
NSDictionary *json = @{
@"title" : @"我是标题",
@"id" : @"123",
@"message" : @"我是message"
};
// 转模型
BModel *model = [BModel modelWithJSON:json];
NSLog(@"model.title = %@",model.title);
NSLog(@"model.ID = %@",model.ID);
NSLog(@"model.message = %@",model.message);
}
@end

多映射的模型继承
- 1、新建一个
CModel类，继承BaseModel
- 2、为
CModel新增两个属性myColor、mySize（后台返回是my_color、my_size），其他属性都从BaseModel继承而来
.h文件，将modelCustomPropertyMapper暴露出来
@interface BaseModel : NSObject
@property (nonatomic, strong) NSString *ID;
@property (nonatomic, strong) NSString *message;
+ (NSDictionary *)modelCustomPropertyMapper;
@end
.m文件，正常映射
@implementation BaseModel
+ (NSDictionary *)modelCustomPropertyMapper{
return @{
@"ID" : @"id"
};
}
@end
.h文件
@interface CModel : BaseModel
@property (nonatomic, strong) NSString *myColor;
@property (nonatomic, strong) NSString *mySize;
@end
.m文件，往父类进行映射
@implementation CModel
+ (NSDictionary *)modelCustomPropertyMapper
{
NSMutableDictionary *superDictM = [[super modelCustomPropertyMapper] mutableCopy];
[superDictM setObject:@"my_color" forKey:@"myColor"];
[superDictM setObject:@"my_size" forKey:@"mySize"];
return superDictM;
}
@end
@implementation ViewController
- (void)viewDidLoad {
[super viewDidLoad];
// 假数据
NSDictionary *json = @{
@"id" : @"123",
@"message" : @"我是message",
@"my_color" : @"我的颜色",
@"my_size" : @"我的大小"
};
// 转模型
CModel *model = [CModel modelWithJSON:json];
NSLog(@"model.ID = %@",model.ID);
NSLog(@"model.message = %@",model.message);
NSLog(@"model.myColor = %@",model.myColor);
NSLog(@"model.mySize = %@",model.mySize);
}
@end

更复杂的模型继承
- 1、首先修改
AModel模型，使其简单的继承NSObject，并且只拥有一个title属性
@interface AModel : NSObject
@property (nonatomic, strong) NSString *title;
@end
- 2、其次修改
BModel模型，使其简单的继承NSObject，并且也拥有一个desc属性
@interface BModel : NSObject
@property (nonatomic, strong) NSString *desc;
@end
- 3、修改基类
BaseModel模型，除了简单的ID、message，还新增拥有多个AModel的数组aModels
@interface BaseModel : NSObject
@property (nonatomic, strong) NSString *ID;
@property (nonatomic, strong) NSString *message;
@property (nonatomic, strong) NSArray<AModel *> *aModels;
+ (NSDictionary *)modelCustomPropertyMapper;
+ (NSDictionary *)modelContainerPropertyGenericClass;
@end
@implementation BaseModel
+ (NSDictionary *)modelCustomPropertyMapper{
return @{
@"ID" : @"id"
};
}
+ (NSDictionary *)modelContainerPropertyGenericClass{
return @{
@"aModels" : [AModel class]
};
}
@end
- 4、新建
DModel模型，继承BaseModel，使其拥有BaseModel的所以属性，额外新增myPower和拥有多个BModel的数组bModels
@interface DModel : BaseModel
@property (nonatomic, strong) NSString *myPower;
@property (nonatomic, strong) NSArray<BModel *> *bModels;
@end
@implementation DModel
+ (NSDictionary *)modelCustomPropertyMapper
{
NSMutableDictionary *superDictM = [[super modelCustomPropertyMapper] mutableCopy];
[superDictM setObject:@"my_power" forKey:@"myPower"];
return superDictM;
}
+ (NSDictionary *)modelContainerPropertyGenericClass {
NSMutableDictionary *superDictM = [[super modelContainerPropertyGenericClass] mutableCopy];
[superDictM setObject:[BModel class] forKey:@"bModels"];
return superDictM;
}
@end
@implementation ViewController
- (void)viewDidLoad {
[super viewDidLoad];
// 假数据
NSDictionary *json = @{
@"id" : @"123",
@"message" : @"我是message",
@"my_power" : @"我的力量",
@"aModels" : @[
@{@"title":@"我是A模型的title"}
],
@"bModels" : @[
@{@"desc":@"我是B模型的desc"}
]
};
// 转模型
DModel *model = [DModel modelWithJSON:json];
NSLog(@"model.ID = %@",model.ID);
NSLog(@"model.message = %@",model.message);
NSLog(@"model.myPower = %@",model.myPower);
NSLog(@"---------------------");
NSLog(@"model.aModels = %@",model.aModels);
AModel *aModel = [model.aModels firstObject];
NSLog(@"model.aModels.title = %@",aModel.title);
NSLog(@"---------------------");
NSLog(@"model.bModels = %@",model.bModels);
BModel *bModel = [model.bModels firstObject];
NSLog(@"model.bModels.desc = %@",bModel.desc);
}
@end

至此，基本常见的数据转模型都已成功，打印也有值
