presentViewController and displaying navigation bar

Question

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];

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.

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: ^ {

    }];
}

Solution 5

Swift version : This presents a ViewController which is embedded in a Navigation Controller.

    override func viewDidAppear(animated: Bool) {
    super.viewDidAppear(animated)

    //  Identify the bundle by means of a class in that bundle.
    let storyboard = UIStoryboard(name: "Storyboard", bundle: NSBundle(forClass: SettingsViewController.self))

    // Instance of ViewController that is in the storyboard.
    let settingViewController = storyboard.instantiateViewControllerWithIdentifier("SettingsVC")

    let navController = UINavigationController(rootViewController: settingViewController)

    presentViewController(navController, animated: true, completion: nil)

}

Hmm..even with the fixed reference to 'topViewController', I'm still seeing the same behavior. I don't think I'm adding the other view controllers on to the nav stack in any special way.

[Jonas Gardner]

That is pretty much what I started with. But the reason I'm not using 'presentModalViewController' is because it is noted as a deprecated API.

[Manish Ahuja]

this is what has been written in the UIViewController class: // Display another view controller as a modal child. Uses a vertical sheet transition if animated.This method has been replaced by presentViewController:animated:completion: // It will be DEPRECATED, plan accordingly. - (void)presentModalViewController:(UIViewController *)modalViewController animated:(BOOL)animated; so simply call the new method and pass nil for completion and you should be good.

[phyzalis]

Thank you, best way to do it if you already have a navigation controller design in your storyboard. You helped me a lot

[Wayne]

Great answer. Updated to use (void)presentViewController:(UIViewController *)viewControllerToPresent animated: (BOOL)flag completion:(void (^)(void))completion

[oarfish]

When I attempt to present a navigation controller, it crashes ('NSInvalidArgumentException', reason: 'Pushing a navigation controller is not supported'). How can this work?

[Vyachaslav Gerchicov]

In my case it shows bar but the other content is placed incorrectly on presenting animation. And only after this animation it jumps into the correct position.

[Manish Ahuja]

@oarfish can you share the code so that I can help debug?

[oarfish]

@ManishAhuja Thanks, but I think i worked around this problem somehow, or let it go. I would have to dig around a lot to find out where it occurred.

[Boris Gafurov]

going back is [self.navigationController popViewControllerAnimated:YES]; popToRoot - going all the way back to the 1st viewcontroller

But How to set when I try your code then only set navigation bar but I cannot change its property like bar tint color, title etc.
