過濾來自類數組

Question

我試圖篩選我的課數組，但我不斷收到一個錯誤，我不知道爲什麼

這是我的代碼：

var shops = [Shops]() 

，並從當我得到的數據服務器和保存它們的元組字符串JSON的

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) 

值沒有任何成員設計

我試圖過濾商店與設計。 Shops是我保存的數據來作爲JSON

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

Answer 1

我覺得問題是此行

var shops = [Shops]() 

這行

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

您正在使用Shops使對象和您正在按照Shop類別過濾

您的代碼應該是這樣的：

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 } 

這裏是你的類Shop

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