【问题描述】：

数据未解析我想将数据解析为字典，然后解析为数组，然后对其进行迭代并将其保存到自定义数组。来自 JSON 结构 "stores" : [,]

代码：

Alamofire.request(NEARBY_STORES, method: .get, parameters: nil, encoding: JSONEncoding.default, headers: headers).responseJSON (response) in

        if response.result.error == nil 
            print(response)
      if let dict = response  as? NSDictionary
       print("dict saved")
        if let stores = dict["stores"] as? Array<AnyObject>
        
            for items in stores
            
            let storeName = items["name"] as? String

            let storeCover = items["cover"] as? String

            let minimumOrder = items["min_order_amt"] as? String

            let  storeRating = items["average_rating"] as? String

            let storeSpeed = items["delievery_time"] as? String

            let  storeLogo = items["logo"] as? String


                let shoplist = shopModel(shopName: storeName!, shopBGImage: storeCover!, shoplogo: storeLogo!, speed: storeSpeed!, accuracy: storeRating!, minimumOrder: minimumOrder!)
                self.shopLists.append(shoplist)
                print("PARSED")

【问题讨论】：

发布预期的 json

JSON 响应很好，但它没有将其转换为字典然后转换为数组

我认为声明字典和数组类型有问题

不要使用 NSDictionary，更喜欢 Dictionary（比如 [String: Any] 显示 JSON，否则我们无法猜测出什么问题。

请发布 json。在您发布之前，我们将无法为您提供指导。

【参考方案1】：

如果 let dict = response as 则替换？ NSDictionary with if let dict = response.result.value as? NSDictionary 和检查

【讨论】：

如果让 stores = dict["stores"] as? Array 请帮我将其转换为数组

【参考方案2】：

我通常使用 SwiftyJSON 来做这个解析。

            if let result = response.result.value 
                let dict = JSON(result)
                print(dict)
                //you can try to print your stores and continue with your logic
                let stores = dict["stores"]

            

【参考方案3】：

if let dict = response  as? [String,Any]
    if let stores = dict["stores"] as? [[String:Any]]
        for items in stores
            //Do stuff here
        
    

【参考方案4】：

试试这个：

Alamofire.request(NEARBY_STORES, method: .get, parameters: nil, encoding: JSONEncoding.default, headers: headers).responseJSON (response) in

    if response.result.error == nil 
        print(response)
  if let dict = response  as? Dictionary<String, Any> ?? [:]
   print("dict saved")
    if let stores = dict["stores"] as? Array ?? []
    
        for items in stores
        
        let itemDict = items as? Dictionary<String, Any> ?? [:]
        let storeName = itemDict["name"] as? String

        let storeCover = itemDict["cover"] as? String

        let minimumOrder = itemDict["min_order_amt"] as? String

        let  storeRating = itemDict["average_rating"] as? String

        let storeSpeed = itemDict["delievery_time"] as? String

        let  storeLogo = itemDict["logo"] as? String


            let shoplist = shopModel(shopName: storeName!, shopBGImage: storeCover!, shoplogo: storeLogo!, speed: storeSpeed!, accuracy: storeRating!, minimumOrder: minimumOrder!)
            self.shopLists.append(shoplist)
            print("PARSED")
