incorrect visible view controller

Question

I am trying to call a segue in my iOS app but am getting the error

Could not find a navigation controller for segue ___

I determined that the issue is that when I try to check the current visibleViewController, it is not the ViewController that the segue is linked to:

if(self.navigationController.visibleViewController == self){
             [self performSegueWithIdentifier:@"login_success" sender:self];
}else{
        NSLog(@"LoginViewController is not currently visible");            
}

My question is, how can I set the correct view controller so I can call the segue?

Here is all my code:

LoginViewController: (The first ViewController)

-(IBAction)registerClick:(id)sender{
    // open up registration
   [self performSegueWithIdentifier:@"registration" sender:self];
}

Registration ViewController (the Modal ViewController)

-(IBAction)finish:(id)sender{
    // return back to login view controller
       [self dismissViewControllerAnimated:YES completion:nil];
}

LoginViewController segue attempt:

    if(self.navigationController.visibleViewController == self){
             [self performSegueWithIdentifier:@"login_success" sender:self];
}else{
        NSLog(@"LoginViewController is not currently visible");            
}

I would guess the "login_success" identifier is unknown to `self`. — ikrabbe, Jul 03 '15 at 20:51
I'm not sure why that is. My LoginViewController is calling a modal, which is then dismissed to return back to LoginViewController. Then why I try to use a segue, I get the error. — scientiffic, Jul 03 '15 at 20:52
for clarification - if I don't call the modal, the segue works fine. — scientiffic, Jul 03 '15 at 20:52
you can do the perform segue and then dismiss that view controller you presented modally, should be okay. — sunshinejr, Jul 03 '15 at 20:59
@sunshine - that's what I have I believe and it's not working. I added all my code above. — scientiffic, Jul 03 '15 at 21:04
I don't see `[self dismissViewControllerAnimated:NO completion:nil]` — sunshinejr, Jul 03 '15 at 22:24
Are you sure the `login_success` segue is called after the modal view controller has been dismissed? — dstudeba, Jul 04 '15 at 04:32
