I know using below statement I can hide navigation bar.
[self.navigationController setNavigationBarHidden:YES animated:NO];
But I want to do this for whole app.
I don't want to write this statement in all files.
So any idea how can I hide navigation bar for whole project?
If you have used Storyboards, then setting the Navigation Bar to None in the Navigation Controller, and ensuring that the top bar is set to 'Inferred' for all view controllers contained within the navigation controller will ensure that the navigation bar will be hidden for all view controllers in the navigation controller.
You can also use
self.navController.navigationBar.hidden = YES;

I have a controller (Search Controller) thats embedded inside a navigation controller and a tab bar controller. I then have a container view inside Search Controller that embeds a navigation controller.
For some reason I cannot hide the navigation controller's tool bar that is embedded inside the container view. This is how I am attempting to hide the tool bar.
-(void)viewWillAppear:(BOOL)animated
{
[super viewWillAppear:animated];
[self.navigationController setToolbarHidden:YES];
[self.tableView reloadData];
}
No matter, the tool bar at the bottom of my controller will have a tool bar that covers my container view's content. Any ideas why this is happening and how I can hide the toolbar/(tab bar?)? Thanks.
Picture of the problem:
I'm not sure exactly what was going wrong or what the proper fix was. But to 'kind of' fix the problem, I simply enlarged the container view underneath my tab bar so that the tab bar I am unable to hide is hidden beneath my universal tab bar.
Try to use:
self.tabBarController.tabBar.hidden = true;
I need some help figuring out the anatomy of my app.
What I need is a tab bar that also have a top navigation bar. And then each view controller within the tab bar will need to have buttons that can transition in new views within this tab. Does that make sense?
So my question is, how should I set this up. Should it be a main tabarviewcontroller and then each view has a separate nagivationcontroller? Or should it be a navigation controller that has the tab bar as a root. And then just use that navigation controller to do any transitions within the viewcontroller?
Thanks!
Your main view can be a UITabBarController, and you can add your UINavigationControllers to the tab bar viewControllers array. Each navigation controller will have a separate navigation bar and function independently. Clicking on a tab will switch to the appropriate navigation controller.
I have a main view controller in Xcode 6 (program is in swift) on which I have a few buttons that lead to certain navigation controllers. When I test the app, the first time I see it it looks fine (without a navigation bar at the top). When I click on a button on main view controller, it shows the navigation controller I selected, everything acts perfectly again. The problem happens when I click on the bar button "back" on that nav controller in order for it to show me my main view controller again. When I'm back to the main view controller, there's a navigation bar at the top that isn't supposed to be there. I want my main view controller to have no navigation bar at the top. I tried to use push, modal and show segues to see if it might be the problem, but I still can't figure it out. Any thoughts on what might be happening?
Sounds like you need to re-hide your navigation bar. To do that, add:
self.navigationController?.navigationBarHidden = true
to the viewWillAppear of whatever view controller for which you'd like to hide the nav bar.
Updated for Swift 3:
self.navigationController?.isNavigationBarHidden = true
In mainViewController, write code to hide navigation bar in viewWillAppear method.
in Objective-C
-(void)viewWillAppear:(BOOL)animated
{
[super viewWillAppear:YES];
[[self navigationController] setNavigationBarHidden:YES animated:NO];
}
In my storyboard I have a view with a segue into a new view that's embedded into a Navigation Controller (so the segue points to the navigation controller). I have the segue set to a Modal transition, however when the new view is animating up, it contains the standard blue navigation bar above the view (which then animates out of view).
Here's what it looks like mid segue: http://i.imgur.com/3eqAQ.png
How do I make it so the modal view animates up but without the navigation bar?
I have tried hiding the navigation bar in the embedded view's init, viewWillAppear, and vieWillLoad methods and that doesn't work.
I event went so far as to create a custom subclass of UINavigationController and set the navigation controller in the storyboard to it.
Thanks!
This may sound pretty simple, but have you tried hiding the navigation bar immediately before the modal segue starts? I had this problem when presenting a modal view controller and adding a [self.navigationController setNavigationBarHidden:YES] immediately before the presentation did the trick for me.
I had almost the same problem, but I wanted to get a navigation bar for my modal transition, as it was always hidden.
There may be two ways for you to remove the navigation bar:
Make sure that your view controller is not embed in a navigation controller, as it would put one by default
Check the "Top Bar" attribute of your previous controller in the workflow and work with none/inferred values depending on your storyboard.

My app has two distincts modes. There's a tab bar controller in the app delegate. There are two tabs, both using subclassed view controllers. The two view controllers essentially contain a nav controller each. The nav controllers have their root view controller, and normally when changing screens, I just push and pop controllers of the respective nav controller. This has the (normal) effect that the bottom tab bar is always visible, all great and sound.
This one time I'd like to present a screen modally however, so that the user can't do anything else than confirm or cancel the page using two buttons, ie I want to hide also the bottom tab bar. This would be a case for presenting the view modally I thought, but the view is presented within the nav controller bounds it seems, so the bottom tab bar is still visible, and this causes confusion in navigation the app. I'm not sure how it's possible that the modally presented view is not hiding the tab bar. Most of the questions around here seem to have the problem the other way around (wanting to (incorrectly) present a modal view and leave the tab bar visible).
These are my attempts:
[self presentModalViewController:controller animated:YES]; // inside tab bar controller :-(
[self.tabBarController presentModalViewController:controller animated:YES]; // nothing is displayed. The new controller is instantly deallocated.
[self.navigationController presentModalViewController:controller animated:YES]; // inside tab bar controller :-(
Investigating this, the self.tabBarController is actually nil. There seems to be no link back to the tab bar controller... I guess, to display modally on top of the tab bar, I need to get a link to that tab bar controller?
I seem to have found a solution, I'm not sure it's kosher, because somehow I wasn't able to use the self.tabBarController pointer of the view controller in which I start the view controller call.
What I did was reach for the app delegate, the app delegate having the tab bar controller defined as a public property. I could use that tab bar controller property to modally display my view controller over everything on the screen.
