i want to store result object into single userdefaults using model and how to retrieve it

Answer 1

From the docs here. Have you tried like this:
//convert the JSON to a raw String
if let rawString = json.rawString() {
userDefaults.set(rawString, forKey: "jsonData")
} else {
print("json.rawString is nil")
}

Answer 2

First create a model for this, using Codable protocol
struct MyJSON : Codable {
let message : String?
let status : String?
let result : JSONResult? // Don't use Result, a keyword in swift
}
struct JSONResult : Codable {
let name : String?
let lastname : String?
let middlename : String?
let id : Int?
}
Then Use the protocol to map the JSON, save the model in UserDefaults.
let jsonString =
"""
{
"message" : "success ",
"status" : "1",
"result" : {
"name" : "abc",
"lastname" : null,
"middlename" : null,
"id" : 20431
}
}
"""
let jsonData = Data(jsonString.utf8)
let data = try JSONDecoder().decode(MyJSON.self, from: jsonData)
// save model in userDefaults
func saveModel() {
if let encoded = try? JSONEncoder().encode(data) {
UserDefaults.standard.set(encoded, forKey: "MySavedValue")
}
}
//get the model
func getModel() -> MyJSON? {
guard let data = UserDefaults.standard.object(forKey: "MySavedValue") as? Data else {
return nil
}
return try? JSONDecoder().decode(MyJSON.self, from: data)
}
how to use
saveModel()
print(getModel()?.message) // print("Success")
