Fabric Twitter Login issue when account is not setup?

Question

I am using Twitter's fabric too login via twitter & to get user's detail. I am using below code for that.

[[Twitter sharedInstance] logInWithCompletion:^
     (TWTRSession *session, NSError *error) {
         if (session) {
             NSLog(@"signed in as %@", [session userID]);
         } else {
             NSLog(@"error: %@", [error localizedDescription]);
         }
     }];

It is working fine when I have configured twitter account in settings of iPhone i.e. added user name & password in twitter app of iPhone. But if that is blank & no twitter account is configured I can not login & will get the error Request failed: unauthorized (401)

Is there any way in which I can ask user to enter his/her username & password ?

Thanks in advance.

You can check like this :

if (![TWTweetComposeViewController canSendTweet]) {
    NSLog(@"No Twitter Accounts");
}

if you want without going settings you need to use fabric way login. In documentation they use button, I don't know your application's lifecycle but at this point you can show this button somewhere and ask them to login maybe. here is some code from documentation :

TWTRLogInButton* logInButton =  [TWTRLogInButton
                                     buttonWithLogInCompletion:
                                     ^(TWTRSession* session, NSError* error) {
    if (session) {
         NSLog(@"signed in as %@", [session userName]);
    } else {
         NSLog(@"error: %@", [error localizedDescription]);
    }
}];
logInButton.center = self.view.center;
[self.view addSubview:logInButton]; 

hope it helps.

Okay so I figured this out for anyone that happens to find this. Go to you developer.twitter app (their website).

Add a callback URL in the apps settings. (doesn't matter what it is)

The button will work now.
