Hide tabBar

[toom]

Hi,
I have an tabBar app, one tab consists of an navigation controller. When I push a view the tabBar should be hidden, just like in the ipod app. I tried this, but it doesn't work:

- (IBAction)MyBtnPressed {
   [[self navigationController] setHidesBottomBarWhenPushed:YES];
   [[self navigationController] pushViewController:[[NewViewController alloc] initWithNibName:@"NewViewController" bundle:nil] animated:YES];
}

Please help,
toom

Set the hide navigation controller member on the new view controller.

[toom]

I put this in the NewViewController.m file:

- (void)awakeFromNib {
	self.navigationController.hidesBottomBarWhenPushed = YES;
}

But it doesn't work.

Set it on your NewViewController object. Not the navcontroller.

[toom]

Sorry but I don't know what to do .

[lapse]

Sure you do.

Your NewViewController is a UIViewController, correct? There's a hidesBottomBarWhenPushed property. Set it and let the navcontroller handle the rest for you.

ahh thank you, i tried this before:

- (BOOL)hidesBottomBarWhenPushed{
	return TRUE;
}

but i forgot to add it to the .h file .

[david_david]

that method worked for me with out adding it in the .h file.

But I am using this way to hide

//Load the view
	AddViewController *aController = [[AddViewController alloc] init];
	
	//Set the view title
	aController.title = @"Add View";
	//hide tabbar
	aController.hidesBottomBarWhenPushed = YES;
	//add it to stack.
	[[self navigationController] pushViewController:aController animated:YES];

Hi,

Is there a way i can hide Tabbar controller on first 3 views and show it on the 4 view.
I am using navigation controller and it is a window based project.
I don't want Tabbar controller at all on first three view.

Thanks

Hi,

I'm having a similar issue.
I have a UITabBarController which is declared in the app delegate, and added to the window as a subview. Each tab in the tab bar controller has a view with a navigation controller and a table view. When I drill down to the last view on the stack (which is just a view, not a table view) I want to hide to tab bar so that I get a nice full screen.
I've tried setting the "hidesBottomBarWhenPushed" property to "YES" in the TableViewController Class, just before I push the detail view onto the stack like so:

detailController.hidesBottomBarWhenPushed = YES;
[self.navigationController pushViewController:detailController animated:YES];

Unfortunately it doesn't do the trick. I'm guessing it might be because the tab bar controller is declared in the appdelegate or something of the sort.

Please help!

Try to hide it before and after the detail view get called.
That means you have to hidesBottomBarWhenPushed at the ViewDidLoad and ViewWillAppear methods.

Hope this helps, if you still have the issue.

I don't know how much this helps your specific problem, but I am trying to do the same thing.

I have made some progress but have not got the problem completely worked out yet.

but what I found is that if you put the following line of code in your "didSelectRowAtIndexPath" method of your UITableView, the viewController pushes the tabbar, but I can get it to reappear when I click to go back to the UITableView:

self.hidesBottomBarWhenPushed = YES; //put in didSelectRowAtIndexPath

[scleland]

- (void)viewWillAppear: (BOOL)animated { self.hidesBottomBarWhenPushed = YES; }

- (void)viewWillDisappear: (BOOL)animated { self.hidesBottomBarWhenPushed = NO; }

[scleland]

So here is the answer I came up with. Dont know if its exactly correct, but it works for my APP.

Put the following code in your "didSelectRowAtIndexPath" method (as apple likes to call it:

self.hidesBottomBarWhenPushed = YES;




Then add the following lines of code to your program:

- (void)viewWillDisappear: (BOOL)animated {
self.hidesBottomBarWhenPushed = NO;
}

It didn't do the trick for me.. do you have any other suggestions?
Basically, I add the tab bar controller to the window in the app delegate. In each tab there's a view controller containing a navigation controller, which in turn displays a table view which can be drilled down. There's 3 levels in the table view, then there's a detail view. When the detail view is shown, I'd like to hide the tab bar.. still no luck. Please let me know if you have any sort of solution. And if you know a better way to display a tab bar with nav controllers and table views I'd like to hear that too. Thanks!!

Simple set hidesBottomBarWhenPushed of the subview before you push to it:

ShowDetails *showDetails = [[ShowDetails alloc] initWithNibName:@"ShowDetails" bundle:nil];
showDetails.hidesBottomBarWhenPushed = YES;
[self.navigationController pushViewController:showDetails animated:YES];
[showDetails release];

Hi,

What about if I want to hide the tabbar in the first view that is loaded (for instance logon)?
Where do I put this piece of code in? AppDelegate?

Thanks

[TUX2K]

if you want an logoin page, I would suggest just present an viewcontroller modal on the first viewcontroller in your tabbarcontroller should do the trick.

Oh yea I didn't know about modal view controllers, looks like exactly what I need...
However, when you say " in your tabbarcontroller should do the trick" thats reffering to the loction of the piece of code right?

[harshal.pandhe]

- (void)viewWillAppear: (BOOL)animated {
[super viewWillAppear:animated];
[self.tabBarController.tabBar setHidden:YES];
}

- (void)viewWillDisappear: (BOOL)animated {
[super viewWillDisappear:animated];
[self.tabBarController.tabBar setHidden:NO];
}

[vbokser]

That worked like a charm. thanks.
