AlamofireJsonToObjects

 [](mailto:edwin@evict.nl?SUBJECT=About AlamofireJsonToObjects)

With AlamofireJsonToObjects it's extremely easy to fetch a json feed and parse it into objects. No property mapping is required. Reflection is used to put the values in the corresponding properties.

AlamofireJsonToObjects is based on the folowing libraries:

• Alamofire is an elegant HTTP Networking library in Swift
• EVReflection is used to parse the JSON result to your objects

This library was greatly inspired by AlamofireObjectMapper

Run the tests to see AlamofireJsonToObjects in action.

Using AlamofireJsonToObjects in your own App

'AlamofireJsonToObjects' is available through the dependency manager CocoaPods. You do have to use cocoapods version 0.36 or later

You can just add AlamofireJsonToObjects to your workspace by adding the folowing 2 lines to your Podfile:

use_frameworks!
pod "AlamofireJsonToObjects"

I have now moved on to Swift 2. If you want to use AlamofireJsonToObjects, then get that version by using the podfile command:

use_frameworks!
pod "AlamofireJsonToObjects", '~> 1.0'

Version 0.36 of cocoapods will make a dynamic framework of all the pods that you use. Because of that it's only supported in iOS 8.0 or later. When using a framework, you also have to add an import at the top of your swift file like this:

import AlamofireJsonToObjects

If you want support for older versions than iOS 8.0, then you can also just copy the AlamofireJsonToObjects.swift to your app.

Sample code

class WeatherResponse: EVObject {
    var location: String?
    var three_day_forecast: [Forecast] = [Forecast]()
}

class Forecast: EVObject {
    var day: String?
    var temperature: NSNumber?
    var conditions: String?
}

class AlamofireJsonToObjectsTests: XCTestCase {
    func testResponseObject() {
        let URL = "https://raw.githubusercontent.com/evermeer/AlamofireJsonToObjects/master/AlamofireJsonToObjectsTests/sample_json"
        Alamofire.request(.GET, URL, parameters: nil)
        .responseObject { (response: WeatherResponse?, error: NSError?) in
            // That was all... You now have a WeatherResponse object with data
        }

        waitForExpectationsWithTimeout(10, handler: { (error: NSError!) -> Void in
            XCTAssertNil(error, "\(error)")
        })
    }
}

The code above will pass the folowing json to the objects:

{  "location": "Toronto, Canada",    
   "three_day_forecast": [
      { "conditions": "Partly cloudy",
        "day" : "Monday",
        "temperature": 20 
      }, { 
        "conditions": "Showers",
        "day" : "Tuesday",
        "temperature": 22 
      }, { 
        "conditions": "Sunny",
        "day" : "Wednesday",
        "temperature": 28 
      }
   ]
}
