I am trying to set up the login for my iOS app using Spotify's SDK. I have the login working, but only without tokens. Once I add these two lines of code:
SPTAuth.defaultInstance().tokenSwapURL = NSURL(string: kTokenSwapURL)
SPTAuth.defaultInstance().tokenRefreshURL = NSURL(string: kTokenRefreshServiceURL)
The login does not work. This is my code for the login.
AppDelegate.swift
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;
