In my application I have to show one screen with navigation bar and then by pushing another controller with no navigation bar.
When I come back I again want to show the navigation bar. But, my navigation bar is not visible with complete height.
I set the navigation bar with no translucent, and style opaque.
can you help me anyone.
this will hide and show navigation bar perfectly:
in first view controller implement:
- (void)viewWillAppear:(BOOL)animated
{
[super viewWillAppear:animated];
[self.navigationController setNavigationBarHidden:NO animated:YES];
}
in pushed view controller:
- (void)viewWillAppear:(BOOL)animated
{
[super viewWillAppear:animated];
[self.navigationController setNavigationBarHidden:YES animated:YES];
}
Show some code...
or try showing the navigation bar from the view controller you're coming back from just before you tell it to go back... Should avoid the issue. But suspect you're doing something else wrong.
Use this method:
In view controller where you want to hide navigation bar add the below code in viewWillAppear
[navigationController setNavigationBarHidden:YES];
So, if you are in some view controller:
In view controller where you want to show navigation bar add the below code in viewWillAppear
[self.navigationController setNavigationBarHidden:NO];

I've got an iOS app that's using a table view with a search bar added to the table view. When a row is tapped, I push another view controller that shows the details of the row that was tapped.
Our table view and detail view both hide the navigation bar.
When the search bar is not active, the navigation bar is disabled on the detail view controller, which is expected.
However, when search is active, the navigation bar shows up on the detail view controller. From what I've read, that's the default behavior for any transitions that occur when search is enabled. Is this accurate?
If so, is there anything I can do to hide the navigation bar? More generally, is there anything I can do to have the push of the detail controller behave the same way regardless of whether search is active or not?
This works
-(void)viewDidLayoutSubviews
{
self.navigationController.navigationBarHidden = YES;
self.navigationController.navigationBar.translucent = YES;
}
In your detail view controller try putting :
- (void)viewWillAppear:(BOOL)animated
{
[super viewWillAppear:animated];
[self.navigationController setNavigationBarHidden:YES animated:animated];
}

I am using UINavigationController to direct some view controllers.In some view controller, I don't want to use UINavigationBar, but in some others i may use. Now I am try to pop one view controller using UINavigationBar to its previous one which hide UINavigationBar. But when poped, there is one wired black space under screen. After you rotate the screen, the space will disappear.
the normal view controller A should be like this:
when press the text button, a view controller B will be pushed, which is as followings:
when click back button on the navigation bar. A will come out.but there is a black space at the bottom.
If rotate the screen, the space will disappear. And also in A's - (void)viewWillAppear:(BOOL)animated method i hide the navigationbar and let the screen autorotate.
- (void)viewWillAppear:(BOOL)animated
{
[self.navigationController setNavigationBarHidden:YES animated:animated];
[super viewWillAppear:animated];
[self willAnimateRotationToInterfaceOrientation:[UIApplication sharedApplication].statusBarOrientation duration:0];
}
whats wrong with this situation? Any help will be appreciated.
I add setNavigationBarHidden: method in the back button action method. it works. If i add this method in viewWillDisappear: method or others, it seems it doesn't work. The navigation bar will have effect on next appear view controller. which means, there will be a black space in the next view controller in the navigation stack.
Finally, i add a action method for the back button and setNavigationBarHidden:YES in the method, which is as follows:
- (void)backBtnClicked:(id)sender
{
[self.navigationController popViewControllerAnimated:NO];
[self.navigationController setNavigationBarHidden:YES];
}
I have a main view controller that lists a bunch of items, and when they tap on one of the items it segues them to the next view. However, in the next view, I don't want the navigation bar to be there, I only want it in the first view (I'm using a UIToolBar for the navigation bar, kind of like in iBooks).
How exactly do I go about achieving this? If I remove the main view controller from the navigation controller completely (unembedding, effectively) I can implement the nav bars selectively, but this solution doesn't allow segues, so it's no good.
My other solution was to call self.navigationController.navigationBarHidden = YES; in viewDidAppear for the second view, but with this, the UIToolBar that I added in my storyboard is pushed under the navigation bar that hasn't been hidden yet, and then when it does get hidden, it disappears and the UIToolBar "falls down", which is a pretty gross effect to the user.
What would be the best way to go about getting this effect?
The best way to do that is the following. In you viewWillAppear: in the first (rootViewController) of your UINavigationController, you set:
-(void)viewWillAppear:(BOOL)animated
{
[super viewWillAppear:animated];
[self.navigationController setNavigationBarHidden:NO animated:animated];
}
and then in you viewWillDisappear, you the the opposite:
-(void)viewWillDisappear:(BOOL)animated
{
[super viewWillDisappear:animated];
[self.navigationController setNavigationBarHidden:YES animated:animated];
}
This way should work without nothing 'ugly' happening to the user.
Here's the deal... I can't get the UINavigation bar to appear on one of my views. I have the whole thing in a NavigationViewController in IB and turned of the navigation bar though IB because I don't want it in most of my app but when I try to show the navigation bar via code, it doesn't show up.
here's the code I used to try to get the nav bar to show up... but didn't work:
[self.navigationController setNavigationBarHidden:NO animated:YES];
[self.navigationController setNavigationBarHidden:NO];
self.navigationController.navigationBarHidden = NO;
self.navigationController.navigationBar.hidden = NO;
Any help will be greatly appreciated
respectfully,

The code you write should only work inside of one of UINavigationController's controllers, not views.
So, if you call it from your view, you should replace self with controller name,in which this view is placed.
using xcode 4.2 and iOS 5 and have nav bar on root controller and four other views (inc UITable view) all i want is to hide nav bar in first root view controller and show in all other views...
Tried following
[self.navigationController setNavigationBarHidden:YES animated:animated];
No luck any ideas?
Use this code in your root controller (or all of your view controllers that you want to have a hidden navigation bar. see [1] though) in order to hide/show the navigation bar according to what you are aiming at:
- (void)viewDidLoad {
...
[self.navigationController setNavigationBarHidden:YES animated:NO];
...
}
- (void)viewWillAppear:(BOOL)animated {
[self.navigationController setNavigationBarHidden:YES animated:animated];
....
}
- (void)viewWillDisappear:(BOOL)animated {
[self.navigationController setNavigationBarHidden:NO animated:animated];
...
}
This is just a possible solution. You could well leave viewWillDisappear undefined in your non-root controllers and define viewWillAppear in your root controller... as you see it most convenient for you.
[1] Hiding the navigation bar in anything but the root controller makes it possible to get stuck in the middle of your navigation hierarchy. Also it is against intuitive navigation in an iOS app to suddenly hide the navigation bar for anything else than the root view.)
You can hide this by using this code
self.navigationController.navigationBar.hidden = YES;
Use this code in view did load
