【问题描述】：

我知道很多这样的问题。我已经在搜索但与我的问题不匹配。

好吧，我会试着用我的代码解释一下

我有这样的数据 API

["profile": 
accountId = 58e470a0c50472851060d083;
androidDeviceId = "[\"3453247ddcf3f809\"]";
androidVersion = 21;
appId =     (
    "c46b4c10-62ce-11e6-bdd4-59e4df4b8410",
    "fac915f0-fe2b-11e6-9dfb-55339bd7be35"
);
appVersion = "v5.1.0";
avatar = "https://account.8villages.com/uploads/images/5/1491366164_bnx1t0rudi.jpg";
birthDate = "12/03/1994";
"channel-group" = android;
communityId = 553e09b251906884443eff85;
coordinates =     
    coordinates =         (
        "106.9602383333333",
        "-6.249333333333334"
    );
    type = Point;
;
crop = "";
crops = "<null>";
customerId = 5369bd85cae84d0e03246a7c;
dateSubmitted =     
    iso = "2017-04-05T04:20:48.483Z";
    timestamp = 1491366048;
;
fullName = "Megi Fernanda";
gender = "Laki-laki";
homeAddress = Payakumbuah;
location = "Kota Payakumbuh";
moderation =     
    at =         
        iso = "2017-04-05T04:20:48.483Z";
        timestamp = 1491366048;
    ;
    by = auto;
    status = moderated;
;

skill = "Budidaya pertanian";
state = "Sumatera Barat";
storeType = "";
subdistrict = "Payakumbuh Barat";
totalConversations =     
    articles = 0;
    forums = 0;
    questions = 2;
    responses = 0;
    storeItems = 1;
;
type = users;
university = "Politeknik Negeri Pertanian Payakumbuh";
, "accessToken": 
key = "lH5aYvnp2JAZ6zoKQK4mpfsxCI0.";
secret = "yfZfTZbsaVIhKCbksGHQnPcPg9mKtoRAKyvjg_cgMeo.";
]

我已经可以得到全名、地址、技能状态等

if let profile = json["profile"] as? NSDictionary 
         let name = profile["fullName"]
         let alamat = profile["Skill"]
 

但我不知道如何在 totalConversation 中获取属性，例如 question、storeItems、points

skill = "Budidaya pertanian";
state = "Sumatera Barat";
storeType = "";
subdistrict = "Payakumbuh Barat";
totalConversations =     
    articles = 0;
    forums = 0;
    questions = 2;
    responses = 0;
    storeItems = 1;
;

我试过了

让 profile = json["profile"]["totalConversation"] 为？ NSDictionary

错误标志：输入“任何？”没有下标成员

【问题讨论】：

欺骗。搜索“输入“任何？”没有下标成员”在这里出现了超过 150 次点击。

【参考方案1】：

您收到该错误是因为json["profile"] 是Any 类型并且它没有任何subscript。所以你需要将json["profile"] 转换为字典，[String: Any] 在 Swift 中是字典类型。

if let profile = json["profile"] as? [String: Any] 
    if let totalConversations = profile["totalConversations"] as? [String: Any] 
        let questions = totalConversations["questions"] as? Int

yaaap 这是工作。我之前已经试过了
