[Bug][Twitter] - iOS Twitter Login

[vladminea94]

Hello. I am trying to implement login with Twitter. I followed the setup guide, so i have the consumer key, consumer secret and the url scheme up and ready.
The problem that I have is that the completion block of loginWithCompletion isn’t called. So i can’t present error messages, like “User allowed permission to system accounts but there were none set up.”, to the user. Thanks in advance

[[Twitter sharedInstance] logInWithCompletion:^(TWTRSession * _Nullable session, NSError * _Nullable error) {
        if (error) {
            NSLog(@"twitter error: %@", error.localizedDescription);
        }
        
        //
        NSMutableDictionary*  parameters = [[NSMutableDictionary alloc] init];
        
        [parameters setObject:session.authToken
                       forKey:@"access_token"];
        [parameters setObject:session.authTokenSecret
                       forKey:@"access_secret"];
        
        [_WSM loginUserWithParameters:parameters
                       forSocialMedia:SocialMediaTwitter
                            andResult:^(WebServiceResponse *response, id responseObject, NSError *error) {
                                
                            }];
    }];

Hey @vladminea94, I created a test app on my end and it seems to be working. I used the following code:

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

Does this code work on your end?

Hello @alexsinger. Thanks for your reply.

Yes, it does. But i ran it on the simulator as i don’t have an iOS device with me now.
My code also works on the simulator but it didn’t work when i ran the app on an iPhone 6 with iOS 10.2.1.
Forgot to mention that

An error (which says that the user didn’t setup his twitter account in System Accounts) is logged in the debugger console and that’s all…

[TwitterKit] did encounter error with message “Unable to authenticate using the system account.”: Error Domain=TWTRLogInErrorDomain Code=2 “User allowed permission to system accounts but there were none set up.”

@vladminea94 hmmm, if I run the above code on a device that doesn’t have a Twitter system account set up, I’m taken to web view where I have the option to login. Can you share the steps you’re taking to get that message?
