Installation

OAuthSwift is packaged as a Swift framework. Currently this is the simplest way to add it to your app:

  • Drag OAuthSwift.xcodeproj to your project in the Project Navigator.
  • Select your project and then your app target. Open the Build Phases panel.
  • Expand the Target Dependencies group, and add OAuthSwift framework.
  • import OAuthSwift whenever you want to use OAuthSwift.

Support Carthage

github "OAuthSwift/OAuthSwift" ~> 1.2.0
  • Run carthage update.
  • On your application targets’ “General” settings tab, in the “Embedded Binaries” section, drag and drop OAuthSwift.framework from the Carthage/Build/iOS folder on disk.

Support CocoaPods

  • Podfile
platform :ios, '10.0'
use_frameworks!

pod 'OAuthSwift', '~> 1.2.0'

swift 3

Use the swift3 branch, or the tag 1.1.2 on main branch

How to

Setting URL Schemes

In info tab of your target Image Replace oauth-swift by your application name

Handle URL in AppDelegate

  • On iOS implement UIApplicationDelegate method
func application(_ app: UIApplication, open url: URL, options: [UIApplicationOpenURLOptionsKey : Any] = [:]) -> Bool {
  if (url.host == "oauth-callback") {
    OAuthSwift.handle(url: url)
  }
  return true
}

⚠️ Any other application may try to open a URL with your url scheme. So you can check the source application, for instance for safari controller :

if (options[.sourceApplication] as? String == "com.apple.SafariViewService") {
  • On macOS you must register an handler on NSAppleEventManager for event type kAEGetURL (see demo code)
func applicationDidFinishLaunching(_ aNotification: NSNotification) {
    NSAppleEventManager.shared().setEventHandler(self, andSelector:#selector(AppDelegate.handleGetURL(event:withReplyEvent:)), forEventClass: AEEventClass(kInternetEventClass), andEventID: AEEventID(kAEGetURL))
}
func handleGetURL(event: NSAppleEventDescriptor!, withReplyEvent: NSAppleEventDescriptor!) {
    if let urlString = event.paramDescriptor(forKeyword: AEKeyword(keyDirectObject))?.stringValue, let url = URL(string: urlString) {
        OAuthSwift.handle(url: url)
    }
}

Authorize with OAuth1.0

// create an instance and retain it
oauthswift = OAuth1Swift(
    consumerKey:    "********",
    consumerSecret: "********",
    requestTokenUrl: "https://api.twitter.com/oauth/request_token",
    authorizeUrl:    "https://api.twitter.com/oauth/authorize",
    accessTokenUrl:  "https://api.twitter.com/oauth/access_token"
)
// authorize
let handle = oauthswift.authorize(
    withCallbackURL: URL(string: "oauth-swift://oauth-callback/twitter")!,
    success: { credential, response, parameters in
      print(credential.oauthToken)
      print(credential.oauthTokenSecret)
      print(parameters["user_id"])
      // Do your request
    },
    failure: { error in
      print(error.localizedDescription)
    }             
)

OAuth1 without authorization

No urls to specify here

// create an instance and retain it
oauthswift = OAuth1Swift(
    consumerKey:    "********",
    consumerSecret: "********"
)
// do your HTTP request without authorize
oauthswift.client.get("https://api.example.com/foo/bar",
    success: { response in
        //....
    },
    failure: { error in
        //...
    }
)

Authorize with OAuth2.0

// create an instance and retain it
oauthswift = OAuth2Swift(
    consumerKey:    "********",
    consumerSecret: "********",
    authorizeUrl:   "https://api.instagram.com/oauth/authorize",
    responseType:   "token"
)
let handle = oauthswift.authorize(
    withCallbackURL: URL(string: "oauth-swift://oauth-callback/instagram")!,
    scope: "likes+comments", state:"INSTAGRAM",
    success: { credential, response, parameters in
      print(credential.oauthToken)
      // Do your request
    },
    failure: { error in
      print(error.localizedDescription)
    }
)

See demo for more examples

Handle authorize URL

The authorize URL allows the user to connect to a provider and give access to your application.

By default this URL is opened into the external web browser (ie. safari), but apple does not allow it for app-store iOS applications.

To change this behavior you must set an OAuthSwiftURLHandlerType, simple protocol to handle an URL

oauthswift.authorizeURLHandler = ..

For instance you can embed a web view into your application by providing a controller that displays a web view (UIWebView, WKWebView). Then this controller must implement OAuthSwiftURLHandlerType to load the URL into the web view

func handle(_ url: NSURL) {
  let req = URLRequest(URL: targetURL)
  self.webView.loadRequest(req)
  ...

and present the view (present(viewController, performSegue(withIdentifier:, ...) You can extend OAuthWebViewController for a default implementation of view presentation and dismiss

Use the SFSafariViewController (iOS9)

A default implementation of OAuthSwiftURLHandlerType is provided using the SFSafariViewController, with automatic view dismiss.

oauthswift.authorizeURLHandler = SafariURLHandler(viewController: self, oauthSwift: oauthswift)

Of course you can create your own class or customize the controller by setting the variable SafariURLHandler#factory.

Make signed request

Just call HTTP functions of oauthswift.client

oauthswift.client.get("https://api.linkedin.com/v1/people/~",
      success: { response in
        let dataString = response.string
        print(dataString)
      },
      failure: { error in
        print(error)
      }
)
// same with request method
oauthswift.client.request("https://api.linkedin.com/v1/people/~", .GET,
      parameters: [:], headers: [:],
      success: { ...

See more examples in the demo application: ViewController.swift

Contributing

See CONTRIBUTING.md

Add a new service in demo app

Integration

OAuthSwift could be used with others frameworks

You can sign Alamofire request with OAuthSwiftAlamofire

To achieve great asynchronous code you can use one of these integration frameworks
