前言：
MJExtension是iOS的字典装模型的一个第三方框架。相对于JSONKit和SBJson相比MJExtension更简单易用、功能更强大。
安装：
使用CocoaPods导入（CocoaPods的使用方法在其他文档里面会介绍）
pod 'MJExtension'
在使用该框架的文件里面导入头文件（推荐在pch文件中导入）
#import "MJExtension.h"
格式单一的字典（没有嵌套），转模型：
@interfaceUser :NSObject
@property (copy,nonatomic)NSString *name;
@property (copy,nonatomic)NSString *sex;
@property (copy,nonatomic) NSString *age;
@end
NSDictionary *dict = @{
@"name" :@"Jack",
@"sex" :@"男",
@"age" : @"20"
}
User *UserModel = [User Mj_objectWithKeyValues:dict];
字典嵌套字典：
@interface People:NSObject
@property (copy,nonatomic) User*User;(上面的User类)
@property (copy,nonatomic)NSString *height;
@property (copy,nonatomic) NSString *wight;
@end
NSDictionary *dict = @{
@"height":@"170"
@"wight":@"70"
@"user":@{
@"name" :@"Jack",
@"sex" :@"男",
@"age" : @"20"
}
}
Poeple *peopleModel = [Pople mj_objectWithKeyValues:dict];
字典嵌套数组，数组里面还有字典：
@interface People:NSObject
@property (copy,nonatomic) NSarray*UserArr;(上面的User类)
@property (copy,nonatomic)NSString *height_2;
@property (copy,nonatomic) NSString *wight;
@end
@implementation People
+(NSDictionary *)mj_objectClassInArray//模型中数组里面的模型
{
return @{
@"UserArr":@"User",//UserArr是自定义的属性名，User是嵌套的字典类名
};
}
+(NSDictionary *)mj_replacedKeyFromPropertyName
{
return @{
@"UserArr":@"User",//模型和字典的字段不对应需要转化
};
}
@end
NSDictionary *dict = @{
@"height":@"170"
@"wight":@"70"
@"UserArr":@[
@{
@"name" :@"Jack",
@"sex" :@"男",
@"age" : @"20"
},
@{
@"name" :@"li",
@"sex" :@"女",
@"age" : @"30"
}
]
}
People *people = [People mj_objectWithKeysValues:dict];
数组转化成模型数组
NSArray *arr = @[
@{
@"name":@"Jack",
@"sex":@"男"，
@"age":@"25"
}
@{
@"name"：@@"wang",
@"sex"：@"男",
@"age":@"26"
}
]
NSArray *UserArrModel = [User mj_objectArrayWithValuesArray:arr];
