Question

我正在尝试实现一个字典数组，但我得到的输出与我的预期不同。

在下面的代码片段中，我创建了一个数组，一个字典并执行了追加操作：

var MemberArray = [[String: Any]]()

let dict = ["member_status":"1", 
            "member_id": memid ,
            "membership_number": memshpid, 
            "name": memname, 
            "mobile":memno ,
            "billing":"1"] as NSDictionary

MemberArray.append(dict as! [String : Any])

我需要这样做：

[
  {
"member_status": 1,
"member_id": 3,
"membership_number": "GI99010286",
"name": "Thomas",
"mobile": "9873684678",
"billing": 0
  },
  {
"member_status": 1,
"member_id": 5,
"membership_number": "GI99010144",
"name": "Raj",
"mobile": "9873684678",
"billing": 1
  }
]

但我得到以下内容：

[
  [
"member_status": 1,
"member_id": 3,
"membership_number": "GI99010286",
"name": "Thomas",
"mobile": "9873684678",
"billing": 0
 ],
 [
"member_status": 1,
"member_id": 5,
"membership_number": "GI99010144",
"name": "Raj",
"mobile": "9873684678",
"billing": 1
  ]]

我如何实现目标？

为此，您必须序列化该数组。这里的数据就是那个数组：

let dataSet = try! JSONSerialization.data(withJSONObject: data, options: JSONSerialization.WritingOptions.prettyPrinted)
let jsonString = NSString(data: dataSet, encoding: String.Encoding.utf8.rawValue)!
