JSON swift 3 从数组到字典的解析问题

JSON Parsing issue in swift 3 from Array to dictionary

我有一个 JSON 作为:

{
  "jsonData": {
    "userDetails": [
      {
        "user_id": "a",
        "first_name": "First1",
        "last_name": "Last1",
        "donation_amount": 841,
        "donation_time": 1452678347523
      },
      {
        "user_id": "b",
        "first_name": "First2",
        "last_name": "Last2",
        "donation_amount": 841,
        "donation_time": 1452678347523
      },
      {
        "user_id": "c",
        "first_name": "First3",
        "last_name": "Last3",
        "donation_amount": 841,
        "donation_time": 1452678347523
      }
    ]
  },
  "total_count": 3
}

并且我在 swift 中使用 swiftlyJSON 进行解析:我的代码如下

    private func processProjectDonorsResponse(response: JSON) {
     //add  to  dictionary
        let jsonObject = response.dictionaryObject!["jsonData"]! as AnyObject
        let details = jsonObject["userDetails"] as! [AnyObject]
        var tempModel = [UserModel]()
        for detail in details {
          let user = UserModel(response: detail as! [String: AnyObject])
          tempModel.append(user)
        }
}

它在 swift 2 中工作正常,但现在我已经升级到 swift 3 我在第 //let details = jsonObject["userDetails"] as! [AnyObject] 行收到警告 as: 从字符串中转换?!到不相关的类型 '[AnyObject]' 总是失败,并崩溃。 如何解决这个问题?

您的代码中的问题在以下行中:

let jsonObject = response.dictionaryObject!["jsonData"]! as AnyObject

只需将此代码更改为以下内容:

let jsonObject = response.dictionaryObject!["jsonData"]! as! [String: AnyObject]

希望这对你有用。
