I have a navigation controller-based app in which I would like to temporarily disable the navigation controller (top left button) at a certain point in the app so that the user can't get out of the view while I'm uploading a file. Is there a way to disable the "back" button so that users can't get out of the view?
You could hide the navigation bar entirely with
- (void)setNavigationBarHidden:animated:
in the appropriate views.
I don't know of an Apple-approved way to disable or otherwise interact with the back button.
In the view controller pushing into the view where you want to hide the back button (NOT in the view controller where you want the back button hidden), do:
self.navigationItem.hidesBackButton = YES;

I have been trying to properly setup a navigation bar in one of my View Controllers for an hour now and have not found any working solutions.
I control-clicked on a button on my app's initial view controller(1st VC) and dragged to another view controller(2nd VC) and selected "modal" as the action segue.
I then added a navigation bar item to my 2nd view controller.
When I run my app on my iPhone, I can tap on the button on my app's initial screen and it will take me to my 2nd VC, and the 2nd VC does display the navigation bar, but the navigation bar does not have the default iOS 7 back arrow to let me go back to the app's initial VC.
I was under the impression that this could be setup exactly like I did above and that the back button functionality would be included by default.
Am I completely lost? Do I need to further customize navigation bar programmatically or with a tick box in the attributes inspector? Is "modal" the wrong action segue option?
I basically just want to have navigation bars at the top of a couple of my VC's so that the user can easily get back to the app's initial screen.
Thanks for the help.
Since you are presenting your second screen (2nd VC) as MODAL from your first screen (1st VC), you will not see the back arrow button on navigation bar. Your understanding about back button works for Navigation view controllers (push segue). For MODAL you need to put a cancel button on second VC's Nav bar and put a dismiss action for that.
I have an app with navigation bar, tab bar and I have a button that, when I push it, it do some things. Well, I'd like to disable the navigation buttons(back button for example) and the tab bar buttons in order to avoid that the user push other buttons while the button's action is running.
Any idea?
Thanks in advance
self.navigationItem.hidesBackButton = YES;
I have a View Controller where I perform a "search as you type". When I press on the SearchBar, hide the Navigation Bar, animated and I also show the scope buttons for my SearchBar. The problem is that when I press on a cell to push a new View Controller the Navigation Bar stays hidden. I KNOW I can set it unhidden, but it will animate from the top. I want to do something similar like in the Email app, when I press on a new cell, a new View Controller is pushed, and the Navigation Bar is animated from the right, like it belongs with the pushed View Controller. How can I make this happen?
Thank you.

Use the UISearchDisplayController to handle the search bar. The behavior you describe is the default behavior.
I have a tab bar with five tabs.
In one tab I have a mapview. I have an info button in the bottom right hand corner of the map. When a user clicks the info button, I want the mapview to flip to a view that has information about the mapview. I'd like a back button in the nav bar to flip back.
How can I do that?
I've managed to create a view controller and make a modal segue, but it doesn't keep the tab bar with it. Worse still, I created a back button on the flipside-viewcontroller with a modal segue back to the mapviewcontroller, and when you go back, the tabbar is gone!
I'm using a storyboard, and most tutorials I find use nibs and xibs. The more control-clicking I can do through the storyboard-IB and the less code the better. Any help is appreciated!
Once you have created in the backButton in the MapInformation view in storyboard, you can add the following to your MapInformation.h/m:
MapInformation.h:
-(IBAction)backButton:(id)sender;
MapInformation.m:
-(IBAction)backButton:(id)sender
{
[self.presentingViewController dismissModalViewControllerAnimated:YES];
}
After that, make sure to connect your IBAction in your storyboard(control-clicking).
I have a root view controller with just a simple navigation button that loads a questionview. When I use pushViewController a back button appears. Instead I want a custom button in the top right of the uinavigationcontroller and I want to remove the back button after the page transition.
how can i achieve this..
Take a look at UINavigationItem. You can accomplish both your goals by properly configuring your view controller's navigation item. Use the -setHidesBackButton:animated: to hide the back button, and the -setRightBarButtonItem:animated: to add your custom button on the right side of the navigation bar.
