arrays - 无法将类型 '__NSSingleEntryDictionaryI' (0x10d249f78) 的值转换为 'NSArray'

Question

这是我的代码:

if let responseDic = response as? Dictionary<String, AnyObject>
                {
                    var temp = Array<Store>.init()

                    var dataDic = responseDic["data"] as? Dictionary<String, AnyObject>
                    if dataDic != nil {

                        for storeList in dataDic!["stores"] as! NSArray {
                                if let store = storeList as? Dictionary<String, AnyObject>
                                {
                                    temp.append((Store(dictionary: store)))
                                }
                            }
                    }

我收到崩溃错误:无法将类型“__NSSingleEntryDictionaryI”(0x10d249f78)的值转换为“NSArray”(0x10d24b008)。对于这一行: for storeList in dataDic!["stores"] as! NSArray

这是我的回复结构:

{
  "data": {
    "stores": {
      "items": [
        {...}]
}
}

您需要转换此内容

for storeList in dataDic!["stores"] as! NSArray

至

if let dic = dataDic!["stores"] as? [String:Any] {}
