# AuthenticationViewController

A simple to use, standard interface for authenticating to OAuth 2.0 protected endpoints via SFSafariViewController.



![Step1](/Screenshots/Demo.gif)



## Instructions

In order to use this View Controller you need to be running iOS 9 on your simulator or device.



### Step 1

Setup the URL Scheme of your app as shown in the image below. (You can find this in the Info tab of your project's settings)



![Step1](/Screenshots/Step1.png)



### Step 2

Prepare your `AppDelegate` to handle this newly created URL Scheme



```swift

func application(app: UIApplication, openURL url: NSURL, options: [String : AnyObject]) -> Bool {



    // Before doing this, you should check the url is your redirect-uri before doing anything. Be safe :)

    if let components = NSURLComponents(URL: url, resolvingAgainstBaseURL: false),

        queryItems = components.queryItems, 

        code = queryItems.first?.value {



        // Let's find the instance of our authentication controller, 

        // it would be the presentedViewController. This is another 

        // reason to check before that we are actually coming from the SFSafariViewController

        if let rootViewController = window?.rootViewController,

            authenticationViewController = rootViewController.presentedViewController as? AuthenticationViewController {

            authenticationViewController.authenticateWithCode(code)

        }



        return true

    }



    return false

}

```



Note that you need to pass the `authentication code` received by your URL scheme to the `AuthenticationViewController` so it can exchange it for an actual `access token`.



### Step 3

Create an `AuthenticationProvider` following the `AuthenticationProvider` protocol.



### Step 4

Instantiate an `AuthenticationViewController` in your code and pass in the provider.



```swift

let provider = OAuthDribbble(clientId: "your-client-id", 

    clientSecret: "your-client-secret", 

    scopes: ["public", "upload"])



let authenticationViewController = AuthenticationViewController(provider: provider)



authenticationViewController.failureHandler = { error in

    print(error)

}



authenticationViewController.authenticationHandler = { token in

    print(token)



    authenticationViewController.dismissViewControllerAnimated(true, completion: nil)

}



presentViewController(authenticationViewController, animated: true, completion: nil)

```



That is it, when you fill in your user account in the `AuthenticationViewController` and if everything went correctly you should get the `access token` in the `authenticationHandler` closure. Otherwise check for any errors in the `failureHandler` closure.



## Installation



Choose one of the following options.



### Carthage



Add the following to your Cartfile:



``` ruby

github "raulriera/AuthenticationViewController"

```



### CocoaPods



Add the following to your Podfile:



``` ruby

pod "AuthenticationViewController"

```



### Manual



Just drag and drop the `AuthenticationViewController/AuthenticationViewController` folder into your project.



## Example



Sometimes it's easier to dig in into some code, included in this project is an example for Dribbble and Instagram. You will still need to edit the source code to provide real `clientId`, `clientSecret`, and your `URL scheme`.
