runtime 创建数据模型

objc_property_t * class_copyPropertyList(Class cls, unsigned int *outCount);//苹果文档获取类所有属性的接口

Class cls //要获取属性的类
unsigned int *outCount //一个指向该属性数组的一个计数指针
objc_property_t* 　//返回一个属性指针数组

具体实现

#import "Model.h"
#import <objc/message.h>
@implementation Model
+(instancetype)getDic:(NSDictionary*)dic{
  Model * model =  [[Model alloc]init];
    unsigned int count = 0;
    objc_property_t * ps = class_copyPropertyList([self class], &count);
    for (int i = 0; i<count; i++) {
        objc_property_t p = ps[i];
        id obj = [dic objectForKey:[NSString stringWithFormat:@"%s",property_getName(p)]];
        if (obj) {
             [mode setValue:obj forKey:[NSString stringWithFormat:@"%s",property_getName(p)]];
        }
    }
    return model;
}
