ios - 如何正确登录到 spotify？

Question

我有一个应用程序允许用户从 spotify 流式传输歌曲。我这里用的是swift。我试图让用户使用 spotify 帐户登录，但我没有得到任何返回。我的应用程序确实打开了 safari 以打开 spotify 登录页面。我已完成登录，但仍未返回任何内容。

我已确保我的callbackuri 与我的 spotify 开发页面中的完全相同，我的 url 方案是我的回调 uri 冒号之前的第一部分，我的其他链接器充满了 < strong>-ObjC

这是我试过的

登录操作:

    let spotifyAuth = SPTAuth.defaultInstance()
    spotifyAuth.clientID = kSpotifyClientID
    spotifyAuth.redirectURL = NSURL(string: kSpotifyCallBackUrl)
    spotifyAuth.requestedScopes = [SPTAuthStreamingScope]

    let spotifyLoginUrl : NSURL = spotifyAuth.loginURL

    UIApplication.sharedApplication().openURL(spotifyLoginUrl)

我的应用代理:

func application(application: UIApplication, openURL url: NSURL, sourceApplication: String?, annotation: AnyObject?) -> Bool{

    println("rene jos1")
    if (SPTAuth.defaultInstance().canHandleURL(url)) {


        println("rene jos2")

        SPTAuth.defaultInstance().handleAuthCallbackWithTriggeredAuthURL(url, callback: { (error : NSError?, session : SPTSession?) -> Void in


            println("rene jos3")
            if error != nil {

                println("Auth error : \(url.description)")
                return
            }

            let userDefaults = NSUserDefaults.standardUserDefaults()
            let sessionData = NSKeyedArchiver.archivedDataWithRootObject(session!)
            userDefaults.setObject(sessionData, forKey: "spotifySession")

            userDefaults.synchronize()

            NSNotificationCenter.defaultCenter().postNotificationName("spotifyLoginSuccesfull", object: nil)

       })

        return true
    }

    if (FBSDKApplicationDelegate.sharedInstance().application(application, openURL: url, sourceApplication: sourceApplication, annotation: annotation)) {

        return true
    }

    return false
}

和我的viewdidload:

 NSNotificationCenter.defaultCenter().addObserver(self, selector: "updateAfterFirstlogin", name: "spotifyLoginSuccesfull", object: nil)
    // Do any additional setup after loading the view.
    spotifyLoginButton.hidden = true

    let userDefaults = NSUserDefaults.standardUserDefaults()

    if let sessionObj : AnyObject = NSUserDefaults.standardUserDefaults().objectForKey("spotifySession") {
         println("rene 2")

        let sessionDataObj : NSData = sessionObj as! NSData
        let session = NSKeyedUnarchiver.unarchiveObjectWithData(sessionDataObj) as! SPTSession
        self.playUsingSession(session)

        if !session.isValid() {

            SPTAuth.defaultInstance().renewSession(session, callback: { (error : NSError!, newsession : SPTSession!) -> Void in

                let sessionData = NSKeyedArchiver.archivedDataWithRootObject(session)
                userDefaults.setObject(sessionData, forKey: "spotifySession")
                userDefaults.synchronize()

                self.session = newsession

                self.playUsingSession(newsession)
                println("rene 3")
            })
        }else{

            println("error refreshing new spotify session")

        }

    }else{

        spotifyLoginButton.hidden = false
         println("rene 4")

    }

那么，我是不是漏掉了什么？任何建议都会很棒

确保你的回调 uri 都是小写字母，我对此有疑问。
