- Support object & array & nested object
- Support decode Datetime field with timestamp, iso8601 format
- Easy to use
AlamofireMapper can be added to your project using Cocoapods by adding the following line to your Podfile:
pod 'AlamofireMapper'
Note: maybe you need to run pod repo update before pod install
Raw json response from server
{
"page":1,
"per_page":3,
"total":12,
"total_pages":4,
"data":[
{
"id":1,
"first_name":"George",
"last_name":"Bluth",
"avatar":"https://s3.amazonaws.com/uifaces/faces/twitter/calebogden/128.jpg"
},
{
"id":2,
"first_name":"Janet",
"last_name":"Weaver",
"avatar":"https://s3.amazonaws.com/uifaces/faces/twitter/josephstein/128.jpg"
},
{
"id":3,
"first_name":"Emma",
"last_name":"Wong",
"avatar":"https://s3.amazonaws.com/uifaces/faces/twitter/olegpogodaev/128.jpg"
}
]
}
Swift class just conform Decodeable
class UserResponse: Decodable {
var page: Int!
var per_page: Int!
var total: Int!
var total_pages: Int!
var data: [User]?
}
class User: Decodable {
var id: Double!
var first_name: String!
var last_name: String!
var avatar: String!
}Then you can use the extension as the follows:
import Alamofire
import AlamofireMapper
let url1 = "https://raw.githubusercontent.com/sua8051/AlamofireMapper/master/user1.json"
Alamofire.request(url1, method: .get
, parameters: nil, encoding: URLEncoding.default, headers: nil).responseObject { (response: DataResponse<UserResponse>) in
switch response.result {
case let .success(data):
dump(data)
case let .failure(error):
dump(error)
}
}Support array response:
let url3 = "https://raw.githubusercontent.com/sua8051/AlamofireMapper/master/user2.json"
Alamofire.request(url3, method: .get
, parameters: nil, encoding: URLEncoding.default, headers: nil).responseObject { (response: DataResponse<[User]>) in
switch response.result {
case let .success(data):
dump(data)
case let .failure(error):
dump(error)
}
}You can custom decode key
class Movie: Decodable {
var id: String!
var name: String!
var movies: Array<String>!
var createdAt: Date?
enum CodingKeys: String, CodingKey {
case id
case name
case movies = "movies[]"
case createdAt
}
}with json as the follows:
{
"name":"paul rudd",
"movies[]":[
"I Love You Man",
"Role Models"
],
"id":"243",
"createdAt":"2014-10-18T12:09:05.255Z"
