Question

我想使用Alamofire将JSON数据转换为Swift中的Dictionary。我正在尝试if let dict = response.result.value as? Dictionary<String, AnyObject> { ... }，不幸的是它不起作用。有什么建议？提前致谢。这是打印我的response.result.value

的示例

Optional(<__NSArrayI 0x6000002893d0>(
{
    category = category1;
    description = description1;
    name = sth1;
    id = 1;
    price = "213";
    type = type1;
},
{
    category = category2;
    description = description2;
    name = sth2;
    id = 2;
    price = "2133";
    type = type4;
},
{
    category = category3;
    description = description3;
    name = sth3;
    id = 3;
    price = "21334";
    type = type5;
}
)
)

Answer 1

因为您的响应是一个数组，所以您需要创建一个字典数组。只有词典不能用于您的上述回复。所以，改变下面的代码。

if let dict = response.result.value as? [[String : AnyObject]] 
{ ... }

Answer 2

您需要逐步从Json中提取数据...... 你可以这样做。

if let arrayOfDic = response.result.value as? [Dictionary<String,AnyObject>]{
        for aDic in arrayOfDic{
            print(aDic)//print each of the dictionaries
            if let price = aDic["price"] as? String{
                print(price)//print price of each dic
            }
        }
    }
