#Intro

This library is heavilly inspired by the SwiftOAuth2 repository from crousselle

AlamofireOauth2 relies on Alamofire, and KeychainAccess

Using AlamofireOauth2 in your own App

'AlamofireOauth2' is now available through the dependency manager CocoaPods. You do have to use cocoapods version 0.36. At this moment this can be installed by executing:

[sudo] gem install cocoapods

If you have installed cocoapods version 0.36 or later, then you can just add EVCloudKitDao to your workspace by adding the folowing 2 lines to your Podfile:

use_frameworks!
pod "AlamofireOauth2"

I have now moved on to Swift 2. If you want to use AlamofireOauth2, then get that version by using the podfile command:

use_frameworks!
pod "AlamofireOauth2", '~> 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 AlamofireOauth2

If you want support for older versions than iOS 8.0, then you can also just copy the AlamofireOauth2 folder containing the 4 classes to your app. besides that you also have to embed the Alamofire, and KeychainAccess libraries

Building the AlamofireOaut2Test demo

  1. Clone the repo to a working directory

  2. CocoaPods is used to manage dependencies. Pods are setup easily and are distributed via a ruby gem. Follow the simple instructions on the website to setup. After setup, run the following command from the toplevel directory of AlamofireOauth to download the dependencies for AlamofireOauth:

pod install
  1. Open the AlamofireOauth.xcworkspace in Xcode and.

  2. Create your own clientID and clientSecret at https://developer.wordpress.com/docs/oauth2/

  3. set the clientID and clientSecret in the wordpressOauth2Settings object in the ViewController

and you are ready to go!

How to use the AlamofireOauth

Below is the sample code for a simple call to the WordPress API while authenticating using OAuth2

class ViewController: UIViewController {

    @IBOutlet weak var result: UITextView!

    @IBAction func startWordpressOauth2Test(sender: AnyObject) {
        self.result.text = ""
        UsingOauth2(wordpressOauth2Settings, self, { token in
            WordPressRequestConvertible.OAuthToken = token
            Alamofire.request(WordPressRequestConvertible.Me())
                .responseJSON { (request, response, json, error ) -> Void in
                self.result.text = "\(json)"
                println("JSON = \(json)")
            }
        }, {
            println("Oauth2 failed")
        })
    }
}

// Create your own clientID and clientSecret at https://developer.wordpress.com/docs/oauth2/
let wordpressOauth2Settings = Oauth2Settings(
    baseURL: "https://public-api.wordpress.com/rest/v1",
    authorizeURL: "https://public-api.wordpress.com/oauth2/authorize",
    tokenURL: "https://public-api.wordpress.com/oauth2/token",
    redirectURL: "alamofireoauth2://wordpress/oauth_callback",
    clientID: "????????????",
    clientSecret: "????????????"
)

// Minimal Alamofire implementation. For more info see https://github.com/Alamofire/Alamofire#crud--authorization
public enum WordPressRequestConvertible: URLRequestConvertible {
    static var baseURLString: String? = wordpressOauth2Settings.baseURL
    static var OAuthToken: String?

    case Me()

    public var URLRequest: NSURLRequest {
        let URL = NSURL(string: WordPressRequestConvertible.baseURLString!)!
        let mutableURLRequest = NSMutableURLRequest(URL: URL.URLByAppendingPathComponent("/me"))
        mutableURLRequest.HTTPMethod = "GET"

        if let token = WordPressRequestConvertible.OAuthToken {
            mutableURLRequest.setValue("Bearer \(token)", forHTTPHeaderField: "Authorization")
        }

        return mutableURLRequest
    }
}
