最近项目中多个页面用到了 商品特价倒计时的功能 为了偷懒 于是自己封装了一个限时抢购 倒计时的view 代码实现如下：
定向价 限时特价 模型代码实现：
#pragma mark 商品定向价模型 @interface STGoodsOrientationPrice : STBaseModel /**定向价**/ @property (nonatomic, copy) NSString *price; /**定向价开始时间**/ @property (nonatomic, copy) NSString *started_at; /***定向价结束时间*/ @property (nonatomic, copy) NSString *expired_at; /**商品分润**/ @property (nonatomic, copy) NSString *rebate; /*** 特价提前曝光中需要的字段 推荐价*/ @property (nonatomic,copy)NSString * promotion_price; /** *特价提前曝光中需要的字段 原价*/ @property (nonatomic,copy)NSString * origin_price; /*** 特价提前曝光需要的背景图片字段*/ @property (nonatomic,copy)NSString * image; /***自定义属性 判断活动是否已经结束 在sku里面会用到*/ @property (nonatomic,assign,getter=isActivityEnd)BOOL activityEnd; @end
@implementation STGoodsOrientationPrice
@end
