Question

我试图过滤我的类数组，但我一直收到错误，我不知道为什么

这是我的代码：

var shops = [Shops]()

当我从服务器获取数据并保存时

 let desgin = subJson["desgin"].stringValue

 let familiy_id = subJson["id"].stringValue


 var info = Shops(shopname: shopName, Logo: logoString, family_id: familiy_id , design : desgin )

self.shops.append(info)

元组字符串json的值没有成员设计

我正试图用设计过滤商店。 Shops是我保存JSON数据的地方

class Shop {
    ...
 var design: String?
    ...
}

Answer 1

我认为问题就在这一行

 var shops = [Shops]()

和这一行

 Shops(shopname: shopName, Logo: logoString, family_id: familiy_id , design : desgin )

您正在使用Shops创建对象，并且您正在根据Shop类进行过滤

您的代码应为：

var shops = [Shop]()


 let desgin = subJson["desgin"].stringValue

 let familiy_id = subJson["id"].stringValue


 var info = Shop(shopname: shopName, Logo: logoString, family_id: familiy_id , design : desgin )

self.shops.append(info)

let filteredArr = self.shops.filter { $0.design != nil }

这是您的班级Shop

class Shop {
    ...
 var design: String?
    ...
}

从类中过滤数组
