如何在 iOS Swift 3 中将 JSON-String 转换为字典数组

Question

I have this String

[{\"label\":\"Issue Name\",\"value\":\"my dirst iOS \",\"_id\":\"issueName\"},{\"label\":\"Issue DueDate\",\"value\":\"15-12-2016\",\"_id\":\"dueDate\"}]

I want to convert it to type [NSDictionary] for example;

[
  {
    "label": "Issue Name",
    "value": "my dirst iOS ",
    "_id": "issueName"
  },
  {
    "label": "Issue DueDate",
    "value": "15-12-2016",
    "_id": "dueDate"
  }
]

Can someone tell me how to do that. I Have Already Tried How to convert a JSON string to a dictionary?

Answer 1

first try to remove the slashes

stringJson.stringByReplacingOccurrencesOfString("\\", withString: "")

then convert it with JsonConverter

func convertToDictionary(text: String) -> Any? {

     if let data = text.data(using: .utf8) {
         do {
             return try JSONSerialization.jsonObject(with: data, options: []) as? Any
         } catch {
             print(error.localizedDescription)
         }
     }

     return nil

}

then

    if let list = self.convertToDictionary(text: stringJson) as? [AnyObject] {

       print(list);
    }

Swift 5 Easy way

//MARK:- Calling
if let list = self.convertToDictionary(text: stringJson) as? [AnyObject] {

   print(list);
}


//MARK:- Remove the Slashes
let text = stringJson.replacingOccurrences(of: "\\", with: "")

//MARK:- Convert it with JsonConverter
func convertToDictionary(text: String) -> Any? {

 if let data = text.data(using: .utf8) {
     do {
         return try JSONSerialization.jsonObject(with: data, options: []) as? Any
     } catch {
         print(error.localizedDescription)
     }
 }

 return nil

}
