runtime的简单练习

很喜欢简书的整体设计模式，于是把以前的笔记稍加整理，搬一部分到这里。

通过runtime实现简单的json解析（仿JsonModel模式）,只实现了一小小部分功能，并没有做太多的容错处理，主要是为了练习一下runtime机制

部分代码：

#import "CWModel.h"
/*
 *"code": "110000",
 *"name": {"code": "110101", "name": "东城区"},
 *"cell": []
 */

/*
 *"code": "110100",
 *"name": "市辖区",
 *"cell": [{
 *"code": "110101",
 *"name": "东城区"
 *}]
 */

@interface CWAreaModel : CWModel

@property (nonatomic, copy) NSString *code;
@property (nonatomic, copy) NSString *name;

@end

@protocol CWAreaModel @end

@interface CWCityModel : CWModel

@property (nonatomic, copy) NSString *code;
@property (nonatomic, copy) NSString *name;
@property (nonatomic, strong) NSArray <CWAreaModel>*cell;

@end

@protocol CWCityModel @end

@interface CWChinaModel : CWModel

@property (nonatomic, assign) BOOL ok;
@property (nonatomic, assign) NSInteger number;
@property (nonatomic, copy) NSString *code;
@property (nonatomic, strong) CWAreaModel *name;
@property (nonatomic, strong) NSArray <CWCityModel>*cell;
@property (nonatomic, strong) NSDictionary *nameDict;

@end

/** 字典转模型 */
+ (instancetype)modelWithDict:(NSDictionary *)dict;
/** 打印 */
+ (NSString *)resolveDict:(NSDictionary *)dict;
