ios - swift 3中从数组到字典的JSON解析问题

Question

我有一个JSON：

{
  "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
}

我正在使用 swiftlyJSON 快速解析：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 中运行良好，但现在我已经升级到 swift 3，我在行收到警告//let details = jsonObject["userDetails"] as! [AnyObject] ：从字符串转换？！到不相关的类型“[AnyObject]”总是失败，并崩溃。如何解决这个问题？

Answer 1

您的代码中的问题在于以下行：

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

只需使用以下内容更改此代码：

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

希望，这对你有用。
