Question

I am using following code

 - (void)linkedInEngineAccessToken:(RDLinkedInEngine *)engine setAccessToken:(OAToken *)token {
        if( token ) {
            [token rd_storeInUserDefaultsWithServiceProviderName:@"LinkedIn" prefix:@"My app name"];
        }
        else {
            [OAToken rd_clearUserDefaultsUsingServiceProviderName:@"LinkedIn" prefix:@"My App name"];

        }
    }

    - (OAToken *)linkedInEngineAccessToken:(RDLinkedInEngine *)engine {
        return [OAToken rd_tokenWithUserDefaultsUsingServiceProviderName:@"LinkedIn" prefix:@"My app name"];
    }

    - (void)linkedInEngine:(RDLinkedInEngine *)engine requestSucceeded:(RDLinkedInConnectionID *)identifier withResults:(id)results {
        NSLog(@"++ LinkedIn engine reports success for connection %@\n%@", identifier, results);
        if( identifier == self.fetchConnection ) {
        //    NSDictionary* profile = results;

        }
    }

    - (void)linkedInEngine:(RDLinkedInEngine *)engine requestFailed:(RDLinkedInConnectionID *)identifier withError:(NSError *)error {
        NSLog(@"++ LinkedIn engine reports failure for connection %@\n%@", identifier, [error localizedDescription]);
    }

    - (void)fetchProfile {
        self.fetchConnection = [self.engine profileForCurrentUser];
        [self.engine updateStatus:@"Download app from the #Apple #AppStore and #Android #GooglePlay market."];
        [self dismissModalViewControllerAnimated:YES];
    }

    #pragma mark - RDLinkedInAuthorizationControllerDelegate

    - (void)linkedInAuthorizationControllerSucceeded:(RDLinkedInAuthorizationController *)controller {
        [self fetchProfile];
    }

    - (void)linkedInAuthorizationControllerFailed:(RDLinkedInAuthorizationController *)controller {

    }

    - (void)linkedInAuthorizationControllerCanceled:(RDLinkedInAuthorizationController *)controller {

    }


    @end

I have set up things correctly. It takes me to linkedIn login page and after login to give permissions I get this error

Failed to load page Error Domain=NSURLErrorDomain Code=-1003 “A
server with the specified hostname could not be found.”
UserInfo=0x81e2250
{NSErrorFailingURLStringKey=http://www.devbee.ca/?oauth_token=MY_TOKEN&oauth_verifier=VERIFIER,

NSLocalizedDescription=A server with the specified hostname could not
be found., NSUnderlyingError=0x810ddc0 “A server with the specified
hostname could not be found.”}

What is wrong?

Is it because of

- (OAToken *)linkedInEngineAccessToken:(RDLinkedInEngine *)engine {
            return [OAToken rd_tokenWithUserDefaultsUsingServiceProviderName:@"LinkedIn" prefix:@"My app name"];
        }

Answer 1

The problem is coming from the fact that http://www.devbee.ca is not up and running. I don’t know what point in your code or configuration you are referring to http://www.devbee.ca, but that’s where there error lies.

I am guessing that in the configuration for your LinkedIn App, you have set the OAuth Accept Redirect URL to http://www.devbee.ca, which is a non-existant URL. But that’s just a guess, you need to dig around to figure out why LinkedIn is redirecting you to http://www.devbee.ca.

Update

It seems that you need to set this OAuth Accept Redirect URL to http://linkedin_oauth/success in your app’s configuration. It states this in the How To on the GitHub project:

Most importantly, the OAuth Redirect URL must be set to:
http://linkedin_oauth/success for the web view’s delegate to be
notified
