我如何获得Alamofire的JSON长度值

Question

我想使用JSON长度在表视图中显示数据，但我不知道如何在json中获取长度

let url = "url/json.php"
Alamofire.request(.GET, url, parameters: ["id":ids])
        .responseJSON { response in
            print(response.request)  // original URL request
            print(response.response) // URL response
            print(response.data)     // server data
            print(response.result)   // result of response serialization

            if let JSON = response.result.value {
                print("JSON: \(JSON)")
            }
    }

示例

    {a=11,b=12},{a=21,b=22}
length = 2

Answer 1

您需要将JSON常量值解析为数组。

Answer 2

斯威夫特3：

{ response in 
    if let allObjects = response.result.value as? NSArray{ 
     print("Array length is \(allObjects.count)")
}
}
