我正在尝试使用Spotify的SDK设置我的iOS应用的登录名.我有登录工作,但只有没有令牌.一旦我添加了这两行代码： @H_502_2@SPTAuth.defaultInstance().tokenSwapURL = NSURL(string: kTokenSwapURL) SPTAuth.defaultInstance().tokenRefreshURL = NSURL(string: kTokenRefreshServiceURL)

登录不起作用这是我的登录代码.

AppDelegate.swift

@H_502_2@let kClientID = "my-client-id" let kCallbackURL = "my-callback-url" let kTokenSwapURL = "my-token-swap-url" let kTokenRefreshServiceURL = "my-token-refresh-url" func application(application: UIApplication,didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool { // Override point for customization after application launch. // Override point for customization after application launch. SPTAuth.defaultInstance().clientID = kClientID SPTAuth.defaultInstance().redirectURL = NSURL(string: kCallbackURL) SPTAuth.defaultInstance().requestedScopes = [SPTAuthStreamingScope,SPTAuthUserReadPrivateScope,SPTAuthPlaylistReadPrivateScope] SPTAuth.defaultInstance().sessionUserDefaultsKey = "SpotifySession" window = UIWindow(frame: UIScreen.mainScreen().bounds) let loginViewController = LoginViewController(nibName: "LogInViewController",bundle: nil) let navigationController = UINavigationController(rootViewController: loginViewController) window?.rootViewController = navigationController window?.makeKeyAndVisible() return true } func application(application: UIApplication,openURL url: NSURL,sourceApplication: String?,annotation: AnyObject) -> Bool { let authCallback : SPTAuthCallback = { error,session in // This is the callback that'll be triggered when auth is completed (or fails). if (error != nil) { print(error); return; } let userDefaults = NSUserDefaults.standardUserDefaults() let sessionData = NSKeyedArchiver.archivedDataWithRootObject(session) userDefaults.setObject(sessionData,forKey: SPTAuth.defaultInstance().sessionUserDefaultsKey) userDefaults.synchronize() AuthHandler.sharedHandler.loginWithSession(session) }; if SPTAuth.defaultInstance().canHandleURL(url) { SPTAuth.defaultInstance().handleAuthCallbackWithTriggeredAuthURL(url,callback:authCallback) return true } return false; }

LoginViewController.swift

@H_502_2@class LoginViewController: UIViewController { let kClientID = "my-client-id" let kCallbackURL = "my-callback-url" let kTokenSwapURL = "my-token-swap-url" let kTokenRefreshServiceURL = "my-token-refresh-url" var session: SPTSession! var logIn: UIButton! var auth : SPTAuthViewController? override func viewWillAppear(animated: Bool) { // set login callback for what happens when session is got AuthHandler.sharedHandler.setLoginCallback({ success in if (success) { self.transitionToPlaylistScreen() } }) // if session is still valid,login let userDefaults = NSUserDefaults.standardUserDefaults() if let sessionObj:AnyObject = userDefaults.objectForKey("SpotifySession") { // session available let sessionDataObj = sessionObj as!

SPTSession if !session.isValid() { SPTAuth.defaultInstance().renewSession(session,callback: { (error:NSError!,renewdSession:SPTSession!) -> Void in if error == nil { let sessionData = NSKeyedArchiver.archivedDataWithRootObject(session) userDefaults.setObject(sessionData,forKey: SPTAuth.defaultInstance().sessionUserDefaultsKey) userDefaults.synchronize() self.session = renewdSession AuthHandler.sharedHandler.loginWithSession(self.session!) } else { print(error.localizedDescription) } }) } else { self.session = session AuthHandler.sharedHandler.loginWithSession(self.session!) } } } override func viewDidLoad() { // add observer for login success NSNotificationCenter.defaultCenter().addObserver(self,selector: Selector("transitionToPlaylistScreen"),name: "loginSuccess",object: nil) // code to set up the login button } func transitionToPlaylistScreen() { if (self.auth != nil) { self.dismissViewControllerAnimated(true,completion: nil) self.auth = nil } let playlistScreen = PlaylistViewController() let navigation = UINavigationController(rootViewController: playlistScreen) dispatch_async(dispatch_get_main_queue(),{ self.presentViewController(navigation,animated: true,completion: nil) }) } func loginToSpotify() { // if session isn't valid,login within app dispatch_async(dispatch_get_main_queue(),{ self.auth = SPTAuthViewController.authenticationViewController() self.auth?.delegate = AuthHandler.sharedHandler self.auth!.modalPresentationStyle = .OverCurrentContext self.auth!.modalTransitionStyle = .CrossDissolve self.modalPresentationStyle = .CurrentContext self.definesPresentationContext = true self.auth!.clearCookies({ dispatch_async(dispatch_get_main_queue(),{ self.presentViewController(self.auth!,animated: false,completion: nil) }) }) }) } }

AuthHandler.swift

@H_502_2@class AuthHandler: NSObject,SPTAuthViewDelegate { static let sharedHandler = AuthHandler() var session: SPTSession? var callback: (Bool -> Void)? func setLoginCallback(callback: (Bool -> Void)) { self.callback = callback } func authenticationViewController(authenticationViewController: SPTAuthViewController!,didFailToLogin error: NSError!) { if let function = callback { function(false) } } func authenticationViewController(authenticationViewController: SPTAuthViewController!,didLoginWithSession session: SPTSession!) { self.loginWithSession(session) } func authenticationViewControllerDidCancelLogin(authenticationViewController: SPTAuthViewController!) { if let function = callback { function(false) } } func loginWithSession(session: SPTSession) { self.session = session SPTAuth.defaultInstance().session = session if let function = callback { function(true) } } }
