在推特授权应用中心中取消对应用的授权，该应用无法再次获取推特的授权

[zhipengbird]

按照正常的开发流程，应用可以正常的调用推特的授权界面，授权并进行分享操作。 但是在推特授权应用中心列表中取消对该应用的授权后，应用分享失败。控制名打出如下提示信息 [TwitterKit] did encounter error with message "Error obtaining user auth token.": Error Domain=TWTRLogInErrorDomain Code=-1 "<?xml version="1.0" encoding="UTF-8"?><errors><error code="415">Callback URL not approved for this client application. Approved callback URLs can be adjusted in your application settings</error></errors>" UserInfo={NSLocalizedDescription=<?xml version="1.0" encoding="UTF-8"?><errors><error code="415">Callback URL not approved for this client application. Approved callback URLs can be adjusted in your application settings</error></errors>} 我做了以下尝试： 查看当前用户 [[Twitter sharedInstance].sessionStore hasLoggedInUsers] 该方法返回有用户登录，但是分享失败。 然后我接着尝试以下方法：

1. 退出当前登录的用户

   for (TWTRSession * Session in [Twitter sharedInstance].sessionStore.existingUserSessions) {
       [[Twitter sharedInstance].sessionStore logOutUserID:Session.userID];
   }

2. 重新调用login方未能进行登录

     [[Twitter sharedInstance] logInWithCompletion:^(TWTRSession * _Nullable session, NSError * _Nullable error) {
               if (session) {
   //分享操作
               } else {
   //错误提示
               }
           }
       }];

   该登录方法不在弹出授权界面，也不会弹出登录页，等待几秒后，返回上述的错误信息。 以上问题是在没有twitter客户端的情况下出现的，有客户端情况下可以正常授权。 以上方式均无法正常获取授权。请各位开发人员帮忙解决。 在取消授权后，再次调用登录方法应可以再试打开授权页进行授权操作。 PS：在示例中，判断当前是否有登录用户，有则可以进行分享，该逻辑存在漏洞，如果用户授权失败或在twitter中取消对该应用的授权，后续操作都会失败，这里应该加上一个授权是否有效的检测。 @garru @mgadda @baroquebobcat @niw @amro please help me, thank you!

I have same issue I am using following pod

TwitterCore (3.1.0)
TwitterKit (3.3.0)

When I call

TWTRTwitter.sharedInstance().logIn(completion: { (session, error) in
     if (session != nil) {
          print("signed in as \(String(describing: session?.userID))")
     } else {
           print("error: \(String(describing: error?.localizedDescription))")
     }
})

Get following error

[TwitterKit] did encounter error with message "Error obtaining user auth token.": Error Domain=TWTRLogInErrorDomain Code=-1 "<?xml version="1.0" encoding="UTF-8"?>Callback URL not approved for this client application. Approved callback URLs can be adjusted in your application settings" UserInfo={NSLocalizedDescription=<?xml version="1.0" encoding="UTF-8"?>Callback URL not approved for this client application. Approved callback URLs can be adjusted in your application settings} error: Optional("Request failed: forbidden (403)")

Facing similar issue. Wonder if anyone has found a solution yet?

Having the same problem here. (From what little I can tell, I don't think it is the logIn() call where it dies, I currently think it might be [[Twitter sharedInstance] startWithConsumerKey:consumerKey consumerSecret:consumerSecret], maybe. Basically in our app we never even get a Twitter UI to show up where anybody could even try to login, we get the 415 error first.)

For Android it seemed to become unblocked when I added another "callback URL" on our app's dashboard on apps.twitter.com, as "twittersdk://".

But iOS is still busted. I tried adding another callback URL as "twitterkit://" since the URL Sschemes contains "twitterkit-", but that hasn't fixed it.

doing this: https://stackoverflow.com/a/50850233/8168867 fixed it for us for iOS just now, apparently.

May be we can change the callbackURL to twitterkit-consumerkey://

@zhipengbird 请问您解决了吗，怎么判断用户取消授权，从而重新进行授权呢，我用 [[Twitter sharedInstance].sessionStore hasLoggedInUsers] 判断的话，就算取消授权，还是返回true
