Navigation controller in modal view

Question

Currently, when a button is tapped, a UIModalPresentationSheet comes up. I'd like to add a navigation bar at the top of this when it slides up. I've tried a lot of things but nothing seems to work. Here's what i'm currently trying and it returns this error.

 AthleteAdd *addAthlete = [self.storyboard instantiateViewControllerWithIdentifier:@"addAthlete"]; UINavigationController *navigationController = [[UINavigationController alloc] initWithRootViewController:addAthlete]; //[self.navigationController pushViewController:addAthlete animated:YES]; addAthlete.delegate = self; addAthlete.modalPresentationStyle = UIModalPresentationFormSheet; // UINavigationController *navController = [[UINavigationController alloc] initWithRootViewController:addAthlete]; [self presentViewController:navigationController animated:YES completion:nil];

But it pushes it up modally, and without the modalpresentationsheet form. How can I make it so the navigation controller is sized correctly?

Try to change your code like this :

 AthleteAdd *addAthlete = [self.storyboard instantiateViewControllerWithIdentifier:@"addAthlete"]; UINavigationController *navigationController = [[UINavigationController alloc] initWithRootViewController:addAthlete]; addAthlete.delegate = self; navigationController.modalPresentationStyle = UIModalPresentationFormSheet; [self presentViewController:navigationController animated:YES completion:nil];

Because here, you try to present addAthlete from itself. So you get this error.

You should present navigationController in which you encased your addAthlete.

[self presentViewController:navigationController animated:YES completion:nil];

You are presenting from current viewcontroller itself.

Try something like,

[self dismissViewControllerAnimated:YES completion:^{ [self.parentViewController presentViewController: navigationController animated:YES completion:nil]; }];
