presentViewController and displaying navigation bar

I have a view controller hierarchy and the top-most controller is displayed as a modal and would like to know how to display the navigation bar when using

'UIViewController:presentViewController:viewControllerToPresent:animated:completion'

The docs for 'presentViewController:animated:completion:' note:

'On iPhone and iPod touch, the presented view is always full screen. On iPad, the presentation depends on the value in the modalPresentationStyle property.'

For 'modalPresentationStyle', the docs say:

The presentation style determines how a modally presented view controller is displayed onscreen. On iPhone and iPod touch, modal view controllers are always presented full-screen, but on iPad there are several different presentation options.

Is there way to ensure that the navigation bar is visible below the status bar once the view control displays itself? Should I interpret the doc as, you don't get any options of iPhone/iPod and only on iPad?

Previously, I was using 'UIViewController:presentModalViewController:animated' which worked fine, but since iOS 5.0, the API has been deprecated so I'm switching over to the new one.

Visually, what I'm looking to do is have the new controller slide in from the bottom of the screen, just like the old API used to do.

[updating with code]:

// My root level view:
UIViewController *vc = [[RootViewController alloc] 
                            initWithNibName:nil 
                            bundle:[NSBundle mainBundle]];
navController = [[UINavigationController alloc] initWithRootViewController:vc];        
....

// Within the RootViewController, Second view controller is created and added 
// to the hierarchy. It is this view controller that is responsible for 
// displaying the DetailView:
SecondTierViewController *t2controller = [[SecondTierViewController alloc] 
                                           initWithNibName:nil
                                           bundle:[NSBundle mainBundle]];

[self.navigationController pushViewController:t2controller animated:YES];

// Created by SecondTierViewController 
DetailViewController *controller = [[DetailViewController alloc] initWithNibName:nil                                                                                 
                                        bundle:[NSBundle mainBundle]];  

controller.modalTransitionStyle = UIModalTransitionStyleCoverVertical;
controller.modalPresentationStyle = UIModalPresentationCurrentContext;

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

Solution 1:

It is true that if you present a view controller modally on the iPhone, it will always be presented full screen no matter how you present it on the top view controller of a navigation controller or any other way around. But you can always show the navigation bar with the following workaround way:

Rather than presenting that view controller modally present a navigation controller modally with its root view controller set as the view controller you want:

MyViewController *myViewController = [[MyViewController alloc] initWithNibName:nil bundle:nil];
UINavigationController *navigationController = 
    [[UINavigationController alloc] initWithRootViewController:myViewController];

//now present this navigation controller modally 
[self presentViewController:navigationController
                   animated:YES
                   completion:^{

                        }];

You should see a navigation bar when your view is presented modally.

Solution 2:

Swift 5.*

Navigation:

guard let myVC = self.storyboard?.instantiateViewController(withIdentifier: "MyViewController") else { return }
let navController = UINavigationController(rootViewController: myVC)

self.navigationController?.present(navController, animated: true, completion: nil)

Going Back:

self.dismiss(animated: true, completion: nil)

Swift 2.0

Navigation:

let myVC = self.storyboard?.instantiateViewControllerWithIdentifier("MyViewController");
let navController = UINavigationController(rootViewController: myVC!)

self.navigationController?.presentViewController(navController, animated: true, completion: nil)

Going Back:

self.dismissViewControllerAnimated(true, completion: nil)

Solution 3:

Can you use:

[self.navigationController pushViewController:controller animated:YES];

Going back (I think):

[self.navigationController popToRootViewControllerAnimated:YES];

Solution 4:

I had the same problem on ios7. I called it in selector and it worked on both ios7 and ios8.

[self performSelector: @selector(showMainView) withObject: nil afterDelay: 0.0];

- (void) showMainView {
    HomeViewController * homeview = [
        [HomeViewController alloc] initWithNibName: @
        "HomeViewController"
        bundle: nil];
    UINavigationController * navcont = [
        [UINavigationController alloc] initWithRootViewController: homeview];
    navcont.navigationBar.tintColor = [UIColor whiteColor];
    navcont.navigationBar.barTintColor = App_Theme_Color;
    [navcont.navigationBar
    setTitleTextAttributes: @ {
        NSForegroundColorAttributeName: [UIColor whiteColor]
    }];
    navcont.modalPresentationStyle = UIModalPresentationFullScreen;
    navcont.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal;
    [self.navigationController presentViewController: navcont animated: YES completion: ^ {

    }];
}
