Native Facebook share on iOS 6

Question

I was wondering if I need to create a facebook app to do a share on facebook.

I don't want the user to actually login or something like this.

As I see in the facebook docs it says that the prerequisite is to "make sure you already set up Facebook Login". I wanted to know if this is really needed or is something I can by pass, since the user is already logged in on their native facebook app.

Here is what I was talking about:

#pragma mark - Share

- (void)sharingStatus {
    if ([SLComposeViewController isAvailableForServiceType:SLServiceTypeFacebook]) {
        NSLog(@"service available");
        self.shareButton.enabled = YES;
        self.shareButton.alpha = 1.0f;
    } else {
        self.shareButton.enabled = NO;
        self.shareButton.alpha = 0.5f;
    }
}

- (IBAction)facebookPost:(id)sender {

    if ([SLComposeViewController isAvailableForServiceType:SLServiceTypeFacebook]) {

        SLComposeViewController *mySLComposerSheet = [SLComposeViewController composeViewControllerForServiceType:SLServiceTypeFacebook];


        NSString *shareText = @"This is my share post!";
        [mySLComposerSheet setInitialText:shareText];

        [mySLComposerSheet addImage:[UIImage imageWithData:[NSData dataWithContentsOfURL:self.imageURL]]];

        [mySLComposerSheet addURL:[NSURL URLWithString:@"http://yourURL.com"]];

        [mySLComposerSheet setCompletionHandler:^(SLComposeViewControllerResult result) {

            switch (result) {
                case SLComposeViewControllerResultCancelled:
                    NSLog(@"Post Canceled");
                    break;
                case SLComposeViewControllerResultDone:
                    NSLog(@"Post Sucessful");
                    break;
                default:
                    break;
            }
        }];

        [self presentViewController:mySLComposerSheet animated:YES completion:nil];
    }
}
