如果model有属性是NSArray数组类型，则设置以下方式自动转换好数组里的对象
@class Shadow, Border, Attachment;
@interface Attributes
@property NSString *name;
@property NSArray *shadows; //Array<Shadow>
@property NSSet *borders; //Set<Border>
@property NSMutableDictionary *attachments; //Dict<NSString,Attachment>
@end
@implementation Attributes
// 返回容器类中的所需要存放的数据类型 (以 Class 或 Class Name 的形式)。
+ (NSDictionary *)modelContainerPropertyGenericClass {
return @{@"shadows" : [Shadow class],
@"borders" : Border.class,
@"attachments" : @"Attachment" };
}
@end
Model 属性名和 JSON 中的 Key 不相同
// JSON:
{
"n":"Harry Pottery",
"p": 256,
"ext" : {
"desc" : "A book written by J.K.Rowing."
},
"ID" : 100010
}
// Model:
@interface Book : NSObject
@property NSString *name;
@property NSInteger page;
@property NSString *desc;
@property NSString *bookID;
@end
@implementation Book
//返回一个 Dict，将 Model 属性名对映射到 JSON 的 Key。
+ (NSDictionary *)modelCustomPropertyMapper {
return @{@"name" : @"n",
@"page" : @"p",
@"desc" : @"ext.desc",
@"bookID" : @[@"id",@"ID",@"book_id"]};
}
@end
一个已经存在的创建好的对象，要给它赋值
@interface People
@property NSString *name;
@proerty CGFloat price;
@end
NSDictionary *param = {@"name":@"黄金国",@"pages":@100};
People *people = [People new];
if([people yy_modelSetWithDictionary:param]){};
