A generic webservice implementation including made easy object mapping with JSON responses

Primary LanguageSwiftMIT LicenseMIT

RONetworking

Is a very light-weight and straighforward JSON to object mapper. You can define your class structure and directly define in there your accessed properties in the JSON file. The whole parsing of the JSON file is done by the library SwiftyJSON https://github.com/SwiftyJSON/SwiftyJSON.

Installation

RONetworking is available through CocoaPods. To install it, simply add the following line to your Podfile:

pod "RONetworking"

How to use

Example Employees.json

[
  {
    "firstName": "John",
    "lastName": "Doe",
    "age": 26
  },
  {
    "firstName": "Anna",
    "lastName": "Smith",
    "age": 30
  },
  {
    "firstName": "Peter",
    "lastName": "Jones",
    "age": 45
  }
]

As next step you have to create your data model (EmplyoeeContainer and Employee).

Employee.swift

class Employee : ROJSONObject {

    required init() {
        super.init();
    }

    required init(jsonData:AnyObject) {
        super.init(jsonData: jsonData)
    }

    required init(jsonString: String) {
        super.init(jsonString:jsonString)
    }

    var firstname:String {
        return Value<String>.get(self, key: "firstName")
    }

    var lastname:String {
        return Value<String>.get(self, key: "lastName")
    }

    var age:Int {
        return Value<Int>.get(self, key: "age")
    }
}

Then to actually map the objects from the JSON response you only have to pass the data into the Employee class as param in the constructor. It does automatically create your data model.

var urlToJSON = "http://prine.ch/employeesWithout.json"

baseWebservice.getArray(urlToJSON, callback: { (status, employees:Array<Employee>) in
    for employee in employees {
        print("Firstname with Array: \(employee.firstname)")
    }
})

Or if you want to store it in a container:

EmployeeContainer.swift

class EmployeeContainer : ROJSONObject {
    required init() {
        super.init();
    }

    required init(jsonData:AnyObject) {
        super.init(jsonData: jsonData)
    }

    required init(jsonString: String) {
        super.init(jsonString:jsonString)
    }

    lazy var employees:[Employee] = {
        return Value<[Employee]>.getArray(self) as [Employee]
    }()
}
  var baseWebservice:BaseWebservice = BaseWebservice();

  var urlToJSON = "http://prine.ch/employeesWithout.json"

  baseWebservice.get(urlToJSON, callback: { (status, employeeContainer:EmployeeContainer) -> () in
      println(employeeContainer.employees[0].firstname)
      println(employeeContainer.employees[0].lastname)

      println("Firstname: " + employeeContainer.employees[0].firstname)
      println("Lastname: " + employeeContainer.employees[0].firstname)
      println("Age: \(employeeContainer.employees[0].age)")

  })

The console output looks then like the following:

John
Doe
Firstname: John
Lastname: John
Age: 26
