「Single View Application」がテンプレです。URL Schemesの設定をしておきます。


2. AppDelegate.swift


//  AppDelegate.swift
//  TwitterOAouth

import UIKit
import OAuthSwift

class AppDelegate: UIResponder, UIApplicationDelegate {

    var window: UIWindow?

    func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
        // Override point for customization after application launch.
        return true

    func applicationWillResignActive(_ application: UIApplication) {
        // Sent when the application is about to move from active to inactive state. This can occur for certain types of temporary interruptions (such as an incoming phone call or SMS message) or when the user quits the application and it begins the transition to the background state.
        // Use this method to pause ongoing tasks, disable timers, and invalidate graphics rendering callbacks. Games should use this method to pause the game.

    func applicationDidEnterBackground(_ application: UIApplication) {
        // Use this method to release shared resources, save user data, invalidate timers, and store enough application state information to restore your application to its current state in case it is terminated later.
        // If your application supports background execution, this method is called instead of applicationWillTerminate: when the user quits.

    func applicationWillEnterForeground(_ application: UIApplication) {
        // Called as part of the transition from the background to the active state; here you can undo many of the changes made on entering the background.

    func applicationDidBecomeActive(_ application: UIApplication) {
        // Restart any tasks that were paused (or not yet started) while the application was inactive. If the application was previously in the background, optionally refresh the user interface.

    func applicationWillTerminate(_ application: UIApplication) {
        // Called when the application is about to terminate. Save data if appropriate. See also applicationDidEnterBackground:.

    // **** 追加 *****
    func application(_ application: UIApplication, open url: URL, sourceApplication: String?, annotation: Any) -> Bool {
        applicationHandle(url: url)
        return true


// MARK: handle callback url
extension AppDelegate {

    func applicationHandle(url: URL) {
        if (url.host == "oauth-callback") {
            OAuthSwift.handle(url: url)
        } else {
            // Google provider is the only one wuth your.bundle.id url schema.
            OAuthSwift.handle(url: url)

3. ViewController.swift


//  ViewController.swift
//  TwitterOAouth

import UIKit
import OAuthSwift

class ViewController: UIViewController {

    var oauthswift: OAuthSwift?

    let consumerData:[String:String] =
        ["consumerKey":"xxxxxxxxxxxxxxxxxxxxxxxxxxxx", // コンシューマキー
        "consumerSecret":"xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"] // コンシューマシークレット

    @IBAction func twitterAuth(_ sender:UIButton) {

    override func viewDidLoad() {
        // Do any additional setup after loading the view, typically from a nib.

        // オートレイアウト使わない場合のコード
        let button = UIButton()
        button.setTitle("Twitter OAuth", for: .normal)
        button.setTitleColor(UIColor.blue, for: .normal)
        button.titleLabel?.font = UIFont.systemFont(ofSize: 15)
        button.bounds = CGRect(x:0,y:0,width:120,height:30)
        button.center = self.view.center
        button.addTarget(self, action: #selector(ViewController.twitterAuth(_:)), for: .touchUpInside)


    override func didReceiveMemoryWarning() {
        // Dispose of any resources that can be recreated.

    // MARK: Twitter
    func doOAuthTwitter(_ serviceParameters: [String:String]){
        let oauthswift = OAuth1Swift(
            consumerKey:    serviceParameters["consumerKey"]!,
            consumerSecret: serviceParameters["consumerSecret"]!,
            requestTokenUrl: "https://api.twitter.com/oauth/request_token",
            authorizeUrl:    "https://api.twitter.com/oauth/authorize",
            accessTokenUrl:  "https://api.twitter.com/oauth/access_token"
        self.oauthswift = oauthswift
        oauthswift.authorizeURLHandler = getURLHandler()
        let _ = oauthswift.authorize(
            withCallbackURL: URL(string: "TwitterOAuth://oauth-callback")!,
            success: { credential, response, parameters in
                self.showTokenAlert(name: serviceParameters["name"], credential: credential)
            failure: { error in

    func getURLHandler() -> OAuthSwiftURLHandlerType {
        if #available(iOS 9.0, *) {
            let handler = SafariURLHandler(viewController: self, oauthSwift: self.oauthswift!)
                handler.presentCompletion = {
                print("Safari presented")
            handler.dismissCompletion = {
                print("Safari dismissed")
            return handler
        return OAuthSwiftOpenURLExternally.sharedInstance

    func showTokenAlert(name: String?, credential: OAuthSwiftCredential) {
        var message = "oauth_token:\(credential.oauthToken)"
        if !credential.oauthTokenSecret.isEmpty {
            message += "\n\noauth_token_secret:\(credential.oauthTokenSecret)"
        self.showAlertView(title: name ?? "Service", message: message)


    func showAlertView(title: String, message: String) {

        let alert = UIAlertController(title: title, message: message, preferredStyle: UIAlertControllerStyle.alert)
        alert.addAction(UIAlertAction(title: "Close", style: UIAlertActionStyle.default, handler: nil))
        self.present(alert, animated: true, completion: nil)
