JustJson 0.1.4

You want to add pod 'JustJson', '~> 0.1' similar to the following to your Podfile:

target 'MyApp' do
  pod 'JustJson', '~> 0.1'
end

Then run a pod install inside your terminal, or from CocoaPods.app.

Alternatively to give it a test run, run the command:

pod try JustJson

To run the example project, clone the repo, and run pod install from the Example directory first.

Requirements

Example

Convert to Dictionary from JSON string

let dict = jsonStr.toDictionary()

Convert Dictionary [String: Any] to JSON string

let jsonString = dict.toJSONStr()

Get Data from Dictionary

let foo = dict[keyPath: "first.second.abc 123"] //return an optional Any

let foo = dict[string: "first.second.abc 123"] //return an optional String

let foo = dict[dict: "first.second.abc 123"] //return an optional Dictionart

let foo = dict[array: "first.second.abc 123"] //return an optional Array

Looping

for foo in dict[arrayValue: "first.second.foos"] {
  print(foo)
}

Object Mapping

Here comes a Dictionary:

userGroup = ["users": [
                [
                    "id" : "1",
                    "name" : "Apple",
                    "age" : 18
                ],
                [
                    "id" : "2",
                    "name" : "Boy",
                    "age" : 19
                ],
                [
                    "id" : "3",
                    "name" : "Cat",
                    "age" : 30
                ],
            ]
        ]

A User model:

struct User: JJMappable {
    var id: String?
    var name: String?
    var age: Int

    init(map: JJMapper) {
        id = map[string: "id"]
        name = map[string: "name"]
        age = map[intValue: "age"]
    }
}

A UserGroup model:

struct UserGroup: JJMappable {
    var users: [User]?

    init(map: JJMapper) {
        users = User.from(map[arrayValue: "users"])
    }
}

If you want to map a user

let data = userGroup[arrayValue: "users"][1] as! [String: Any]
let user: User? = User.from(data)

If you want to get users

let users: [Users]? = User.from(userGroup[arrayValue: "users"])

Nested mapping

let _userGroup = UserGroup.from(userGroup)
