// 归档
- (void)encodeWithCoder:(NSCoder *)enCoder{
//归档存储自定义对象
unsigned int count = 0;
//获得指向该类所有属性的指针
objc_property_t *properties = class_copyPropertyList([self class], &count);
for (int i =0; i < count; i ++) {
//获得
objc_property_t property = properties[i];
//根据objc_property_t获得其属性的名称--->C语言的字符串
const char *name = property_getName(property);
NSString *key = [NSString stringWithUTF8String:name];
// 编码每个属性,利用kVC取出每个属性对应的数值

free(properties);
}
// 解档
- (id)initWithCoder:(NSCoder *)aDecoder{
//归档存储自定义对象
unsigned int count = 0;
//获得指向该类所有属性的指针
objc_property_t *properties = class_copyPropertyList([self class], &count);

//根据objc_property_t获得其属性的名称--->C语言的字符串
const char *name = property_getName(property);

//解码每个属性,利用kVC取出每个属性对应的数值
[self setValue:[aDecoder decodeObjectForKey:key] forKeyPath:key];
}
free(properties);
return self;
}
@end
然后其他类使用，只要继承它就好了
#import "BaseModel.h"
@interface PeopleModel : BaseModel
@property (nonatomic, copy) NSString *name;
@property (nonatomic, assign) NSInteger age;
@end
