How does one hide the UITabBar programmatically? It's been asked and answered multiple times on SO, but the answers seem to come in roughly two varieties:
1) Using a navigation controller, one can hide the next vc's tab bar before the push using hidesBottomBarWhenPushed property. Typical answer here.
2) Walk through the tabbar controller's view hierarchy and modify the tab bar's frame and/or visibility. Typical answer here.
But both sorts of answers fall short, imo. 1) What if we need to hide the tab bar on the view we are on, say when rotating to landscape. 2) A half page of code waking through an Apple library's private view hierarchy is a. cumbersome, b. prone to unforseen breaking, c. possibly a blocker for app approval.
So what's an app to do? Is the answer that it's not allowed? Is there an apple document ref supporting that? It would be a sad answer. Imo, the rotation case is a legitimate reason for hiding the tab bar.
Thanks in advance for your help.
Sorry for the delayed response but I've pulled my code and you can see how I rotate my device to show a 'Map View' in full screen in landscape only.
-(void)willAnimateRotationToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation duration:(NSTimeInterval)duration {
if(toInterfaceOrientation == UIInterfaceOrientationLandscapeRight || toInterfaceOrientation == UIInterfaceOrientationLandscapeLeft) {
[self hideTabBar:self.tabBarController];
[self.view bringSubviewToFront:self.eventsMapView];
self.eventsMapView.bounds = self.view.bounds;
self.eventsMapView.frame = CGRectMake(0, -208, self.view.frame.size.width, 300);
} else if(toInterfaceOrientation == UIInterfaceOrientationPortraitUpsideDown || toInterfaceOrientation == UIInterfaceOrientationPortrait) {
[self showTabBar:self.tabBarController];
[self.view sendSubviewToBack:self.eventsMapView];
}
}
And since we call methods within that to actually hide and show the tab bar, we need to define those methods in our .m file as well:
#pragma mark - Tab Bar Methods -
-(void)hideTabBar:(UITabBarController *)tabbarcontroller {
[UIView beginAnimations:nil context:NULL];
[UIView setAnimationDuration:0.3];
for(UIView *view in tabbarcontroller.view.subviews) {
if([view isKindOfClass:[UITabBar class]]) {
[view setFrame:CGRectMake(view.frame.origin.x, 480, view.frame.size.width, view.frame.size.height)];
} else {
[view setFrame:CGRectMake(view.frame.origin.x, view.frame.origin.y, view.frame.size.width, 480)];
}
}
[UIView commitAnimations];
}
-(void)showTabBar:(UITabBarController *)tabbarcontroller {
[UIView beginAnimations:nil context:NULL];
[UIView setAnimationDuration:0.3];
for(UIView *view in tabbarcontroller.view.subviews) {
if([view isKindOfClass:[UITabBar class]]) {
[view setFrame:CGRectMake(view.frame.origin.x, 431, view.frame.size.width, view.frame.size.height)];
} else {
[view setFrame:CGRectMake(view.frame.origin.x, view.frame.origin.y, view.frame.size.width, 431)];
}
}
[UIView commitAnimations];
}
If you're already within a Tab Bar Controller then you need to make sure every child (or individual tab ViewController) returns TRUE for orientation like below.
-(BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
return TRUE;
}
Hope this helps - if you have any questions leave a comment and I'll update my answer to show it off better.
You can find some useful code here. You can call hideTabbar from your shouldrotate: method
2021 answer. Xcode 12.
Create a new layout for when in Landscape mode. in the below picture, I created wAny hCompact (hC) attribute and then set it as hidden.
I have several view controllers for various parts of a game I am working on, let's call them screens 1,2,3,4.
I would like to be able to start the game up in screen 1, then show 2, 3, 4 and then go back to screen 1 and start all over again (sometimes I want to leave out #3, etc). I have managed to get this functionality with the UITabBarController but I couldn't figure out how to hide the tab control itself. If I hid the actual control it would just display a white bar in its place. If I tried to resize the view it worked on the first screen, then the others appeared to be twice the screen size (set in viewWillAppear):
[[self view] setFrame:[[UIScreen mainScreen] bounds]];
Has anybody managed to get this sort of thing working? Would I be able to use a navigation controller to do this?
I suggest you to use UINavigationController for this because for your purpose this can be done with UINavigationController instead of UITabBarController.
But if you want to continue with UITabBarController then you can hide your UITabBarController by calling this method in your app delegate:
- (void) hideTabBar:(UITabBarController *) tabbarcontroller {
[UIView beginAnimations:nil context:NULL];
[UIView setAnimationDuration:0.5];
for(UIView *view in tabbarcontroller.view.subviews)
{
if([view isKindOfClass:[UITabBar class]])
{
[view setFrame:CGRectMake(view.frame.origin.x, 480, view.frame.size.width, view.frame.size.height)];
}
else
{
[view setFrame:CGRectMake(view.frame.origin.x, view.frame.origin.y, view.frame.size.width, 480)];
}
}
[UIView commitAnimations];
}
developers!
Im currently working on an app that uses the Tab Bar Application template. What I wanna do
is to simulate a startpage for my app that corresponds to the first tab.
So when the app start the first tab is selected and the UITabBar should not be visible.
In this "startview" there is multiple buttons that acts like the rest of the tabs, so for instance i press button #2 and the second tab view is pushed and the UITabBar is again visible.
My problem is that i have a way to hide the bar but the subview is not resizing to fullscreen.
By using:
[self.tabBarController.tabBar setHidden:YES];
I've also tried to use:
self.hidesBottomBarWhenPushed = YES;
But it seems to have no effect and I'm not sure where to add the code since I'm using
the template.
Anyone knows how to implement this by using the Tab Bar Application template?
I'm guessing it should be at the:
- (void)tabBarController:(UITabBarController *)tabBarController didSelectViewController: (UIViewController *)viewController
But I've tried that and that method is never being called...
Many thanks,
Robert
THis code may help you to Hide tabbarcontroller and resize the viewcontroller.
- (void) hideTabBar:(UITabBarController *) tabbarcontroller {
int height = 480;
[UIView beginAnimations:nil context:NULL];
[UIView setAnimationDuration:0.3];
for(UIView *view in tabbarcontroller.view.subviews) {
if([view isKindOfClass:[UITabBar class]]) {
[view setFrame:CGRectMake(view.frame.origin.x, height, view.frame.size.width, view.frame.size.height)];
}
else {
[view setFrame:CGRectMake(view.frame.origin.x,view.frame.origin.y, 320, 436)];
}
}
[UIView commitAnimations];
}
This second method may help you to set tababr again in view
- (void) showTabBar:(UITabBarController *) tabbarcontroller {
int height = 480;
[UIView beginAnimations:nil context:NULL];
[UIView setAnimationDuration:0.3];
for(UIView *view in tabbarcontroller.view.subviews) {
if([view isKindOfClass:[UITabBar class]]) {
[view setFrame:CGRectMake(view.frame.origin.x, height, view.frame.size.width, view.frame.size.height)];
}
else {
[view setFrame:CGRectMake(view.frame.origin.x, view.frame.origin.y, view.frame.size.width, height)];
}
}
[UIView commitAnimations];
}
please understand code before implementing it in your code...
I am trying to hide the tabbar controller and display uiimageview similar to how it is done in native photo library of iphone. I have already created the library but I am having problem in displaying the images on next view by hiding tabbar. I am able to hide the tabbar but when I try to add the uiimageview it does not expend to space taken up by tab bar. I want my uiimageview to stretch till bottom of the screen.
I even want to add a button on that empty space but I am not able to do it.
My code to hide tab bar:
self.tabBarController.tabBar.hidden = YES;
Can some one please help me?
Thanks
Pankaj
Try this
self.tabBarController.tabBar.hidden = YES;
and
[imageView setFrame:CGRectMake(0,0,320,480)];
just use below two methods to hide or show tabbar controller. put this methods in delegate class so it's easy to call from any class.
- (void) hideTabBar:(UITabBarController *) tabbarcontroller {
int height = 480;
[UIView beginAnimations:nil context:NULL];
[UIView setAnimationDuration:0.3];
for(UIView *view in tabbarcontroller.view.subviews) {
if([view isKindOfClass:[UITabBar class]]) {
[view setFrame:CGRectMake(view.frame.origin.x, height, view.frame.size.width, view.frame.size.height)];
}
else {
[view setFrame:CGRectMake(view.frame.origin.x,view.frame.origin.y, 320, 436)];
}
}
[UIView commitAnimations];
}
- (void) showTabBar:(UITabBarController *) tabbarcontroller {
int height = 480;
[UIView beginAnimations:nil context:NULL];
[UIView setAnimationDuration:0.3];
for(UIView *view in tabbarcontroller.view.subviews) {
if([view isKindOfClass:[UITabBar class]]) {
[view setFrame:CGRectMake(view.frame.origin.x, height, view.frame.size.width, view.frame.size.height)];
}
else {
[view setFrame:CGRectMake(view.frame.origin.x, view.frame.origin.y, view.frame.size.width, height)];
}
}
[UIView commitAnimations];
}
You need to set the frame of the bottom subview of the tabBarController's view property, like so:
self.tabBarController.tabBar.hidden = YES;
UIView* subview = (UIView*)[self.tabBarController.view.subviews objectAtIndex:0];
imageView.frame = subview.frame = self.window.bounds;
This is something I've used in some form in a couple of in-production products. Whether or not you actually want to utilize self.window.bounds depends on if your current class has a window property pointing to the mainWindow instance of UIWindow, whether you are supporting multiple orientations (bounds of window stays the same regardless of the current UIInterfaceOrientation, view controllers rotate, windows do not) and if you need to account for the status bar. If accounting for the status bar (UIStatusBar), offset the y & height by 20. Casting subview to UIView allows you to use dot syntax in this case (the static analyzer can't tell which objects are in an array).
I have been struggled on that for hours. Finally I found a solution. Just follow the following steps:
Tick the box Hide Bottom Bar on Push in your child view controller (the one you want to hide the tab bar) from Storyboard.
Add the following code in the viewWillAppear method in your root view controller: self.tabBarController?.tabBar.hidden = false.
Add the following code in the viewWillAppear method in your pushed view controller: self.tabBarController?.tabBar.hidden = true.
That's all. It just works!
I have an application that uses a UITabBarController to switch between modes. When in a certain mode, I'd like to hide the tab bar until the steps of that mode have been completed. Note that I'm not using a navigation controller so I can't use the setHidesBottomBarWhenPushed method on the navigation controller to hide the tab bar.
Prior to iOS 8, When I attempt to hide the tarbar using:
self.tabBarController.tabBar.hidden = YES
the tab bar goes away, but it leaves a 50 pixel blank area at the bottom of the screen where the tab bar used to be. I can't seem to figure out how to fill that area. Anything in the UI that is in that area is clipped and cannot be seen.
Any ideas if this is even possible? I'd really like to stay away from the navigation controller.
Here's my code for that:
This is, of course, mucking with the goings on in the controller's view hierarchy. It could change/break. This uses defined APIs, so Apple won't care, but they won't care about breaking your code, either.
- (void)hideTabBar {
UITabBar *tabBar = self.tabBarController.tabBar;
UIView *parent = tabBar.superview; // UILayoutContainerView
UIView *content = [parent.subviews objectAtIndex:0]; // UITransitionView
UIView *window = parent.superview;
[UIView animateWithDuration:0.5
animations:^{
CGRect tabFrame = tabBar.frame;
tabFrame.origin.y = CGRectGetMaxY(window.bounds);
tabBar.frame = tabFrame;
content.frame = window.bounds;
}];
// 1
}
- (void)showTabBar {
UITabBar *tabBar = self.tabBarController.tabBar;
UIView *parent = tabBar.superview; // UILayoutContainerView
UIView *content = [parent.subviews objectAtIndex:0]; // UITransitionView
UIView *window = parent.superview;
[UIView animateWithDuration:0.5
animations:^{
CGRect tabFrame = tabBar.frame;
tabFrame.origin.y = CGRectGetMaxY(window.bounds) - CGRectGetHeight(tabBar.frame);
tabBar.frame = tabFrame;
CGRect contentFrame = content.frame;
contentFrame.size.height -= tabFrame.size.height;
}];
// 2
}
Edit:
An anonymous user has suggested the following addition for 7.0 (i have not tested this, and could not say whether it is a workaround or an ideal implementation):
// 1. To Hide the black line in IOS7 only, this extra bit is required
if (SYSTEM_VERSION_GREATER_THAN_OR_EQUAL_TO(#"7.0")) {
[self.tabBarController.tabBar setTranslucent:YES];
}
// 2. For IOS 7 only
if (SYSTEM_VERSION_GREATER_THAN_OR_EQUAL_TO(#"7.0")) {
[self.tabBarController.tabBar setTranslucent:NO];
}
Edit: Entirely untested in 8.x and likely lacking in some layouts.
Like Steve, I haven't found a clean way to do this (even though Apple Photopicker does something similar). Here is what I have done:
if (systemAction)
{
// Reveal tab bar back
CGRect bounds = [[UIScreen mainScreen] bounds];
CGRect tabBarFrame = self.tabBarController.tabBar.frame;
self.tabBarController.view.frame = CGRectMake(0,0,bounds.size.width,bounds.size.height);
self.toolBar.hidden = YES;
systemAction = NO;
}
else
{
//hide tab bar
CGRect bounds = [[UIScreen mainScreen] bounds];
CGRect tabBarFrame = self.tabBarController.tabBar.frame;
CGRect navigationBarFrame = self.navigationController.navigationBar.frame;
self.tabBarController.view.frame = CGRectMake(0,0,bounds.size.width,bounds.size.height+tabBarFrame.size.height);
self.toolBar.hidden = NO;
CGRect frame = self.toolBar.frame;
frame.origin.y = bounds.size.height - frame.size.height - navigationBarFrame.size.height;
self.toolBar.frame = frame;
systemAction = YES;
}
What it is doing is pushing the view down so I can display a toolbar (and not hiding it). Obviously this is for only the 'root view' of a tabbar + navigation controller. For any subsequent views you can set the 'hidesBottomBarWhenPushed' on the viewcontroller you are pushing.
I tried a number of the solutions above, but no joy in iOS 8. I find that setting in viewWillAppear the following works for me. Should work in iOS 7 as the extendedLayoutIncludesOpaqueBars was introduced then.
self.extendedLayoutIncludesOpaqueBars = true
self.tabBarController?.tabBar.isHidden = true
self.tabBarController?.tabBar.isOpaque = true
and if you need to turn tabBars on again when you leave to use the following in viewWillDisappear.
self.tabBarController?.tabBar.isHidden = false
self.tabBarController?.tabBar.isOpaque = false
I use this to allow a return from a transition to keep the TabBar hidden. Not used it in a button action but if like me you find nothing above now works, this could be the basis of a programmable solution.
It's a bit late in the day, but of all the answers to the question that I've trawled through this afternoon, this is the one that worked best for me.

I use only this single line to achieve this. I use prepareForSegue method before showing the view controller having the tab bar.
-(void) prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender{
if([segue.identifier isEqualToString:#"showLogin"]){
[segue.destinationViewController setHidesBottomBarWhenPushed:YES];
}
}
I had worked on almost the same case, actually used the code from http://www.developers-life.com/hide-uitabbarcontrolleruitabbar-with-animation.html and made it better according to my needs, this might help others too.
I am using a UISplitViewController as the root view controller and its detail portion is a UITabBarController, I had to hide the tabbar in portrait mode:
// In UITabBarController's custom implementation add following method,
// this method is all that will do the trick, just call this method
// whenever tabbar needs to be hidden/shown
- (void) hidetabbar:(NSNumber*)isHidden {
UITabBarController *tabBarController=self;
[UIView beginAnimations:nil context:NULL];
[UIView setAnimationDuration:0.5];
CGRect tabbarFrame=CGRectZero;
for(UIView *theView in tabBarController.view.subviews) {
//NSLog(#"%#", view);
if([theView isKindOfClass:[UITabBar class]]) {
tabbarFrame=theView.frame;
if ([isHidden boolValue]) {
tabbarFrame=CGRectMake(tabbarFrame.origin.x,
tabBarController.view.frame.size.height,
tabbarFrame.size.width,
tabbarFrame.size.height);
} else {
tabbarFrame=CGRectMake(tabbarFrame.origin.x,
tabBarController.view.frame.size.height - tabbarFrame.size.height,
tabbarFrame.size.width,
tabbarFrame.size.height);
}
theView.frame=tabbarFrame;
break;
}
}
for(UIView *theView in tabBarController.view.subviews) {
if(![theView isKindOfClass:[UITabBar class]]) {
CGRect theViewFrame=theView.frame;
if ([isHidden boolValue]) {
theViewFrame=CGRectMake(theViewFrame.origin.x,
theViewFrame.origin.y,
theViewFrame.size.width,
theViewFrame.size.height + tabbarFrame.size.height);
} else {
theViewFrame=CGRectMake(theViewFrame.origin.x,
theViewFrame.origin.y,
theViewFrame.size.width,
theViewFrame.size.height - tabbarFrame.size.height);
}
theView.frame=theViewFrame;
}
}
[UIView commitAnimations];
}
I used following code to call the hidetabbar: method
//In my UISplitViewController's custom implementation
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
#synchronized(self){
//change the self.splitDetailController to your UITabBarController's object
[self.splitDetailController
performSelector:#selector(hidetabbar:)
withObject:[NSNumber numberWithBool:UIInterfaceOrientationIsLandscape(interfaceOrientation)]
afterDelay:0.5];
}
return YES;
}
I tested this code to work in simulator only, let me know if it works on device too ;-)
Do you have the autoResizingMask set on the sub view?
view.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight;
Something like that should do the trick and allow the view sitting atop the stack to re-size.
The obvious solution, keeping your original architecture, would have been to present that view modally:
- (void)tabBarController:(UITabBarController *)tb
didSelectViewController:(UIViewController *)vc {
if (tb.selectedIndex == MODALONE) {
UIViewController* mod =
[[UIViewController alloc] initWithNibName: #"ModalView"
bundle: nil];
[tb presentModalViewController:mod animated:NO];
[mod release];
}
}
The view now covers the entire screen (except for the status bar is there is one) including the tab bar, so it looks as if the tab bar has gone away in response to the user pressing that tab bar item.
autoresizing mask has an enumeration. Try to set all the options and check if autoresize subviews option is checked in parent view
You can create Tabbar Category and show/Hide easily. and you can access full view.
create category #import "UITabBarController+HideTabBar.h"
#implementation UITabBarController (HideTabBar)
- (void)hideTabBarAnimated:(BOOL)animated
{
CGRect statusbarFrame = [UIApplication sharedApplication].statusBarFrame;
CGRect tabBarControllerFrame = self.view.frame;
if (statusbarFrame.size.height>20)
{
tabBarControllerFrame.size.height = screenSize.size.height + self.tabBar.frame.size.height - 20.0;
}
else
{
tabBarControllerFrame.size.height = screenSize.size.height + self.tabBar.frame.size.height ;
}
if (animated) {
[UIView animateWithDuration:0.2 animations:^{
[self.view setFrame:tabBarControllerFrame];
} completion:^(BOOL finished) {
}];
}
else
[self.view setFrame:tabBarControllerFrame];
}
- (void)showTabBarAnimated:(BOOL)animated {
CGRect statusbarFrame = [UIApplication sharedApplication].statusBarFrame;
CGRect tabBarControllerFrame = self.view.frame;
if (statusbarFrame.size.height>20)
{
tabBarControllerFrame.size.height = screenSize.size.height - 20.0;
}
else
{
tabBarControllerFrame.size.height = screenSize.size.height ;
}
if (animated) {
[UIView animateWithDuration:0.2 animations:^{
[self.view setFrame:tabBarControllerFrame];
} completion:^(BOOL finished) {
}];
}
else
[self.view setFrame:tabBarControllerFrame];
}
#end
Note : use statusbarFrame is used when hotspot or call is ON so tabbar would not cut down.
Now Import category in which you class you want to use methods and just call below methods to hide or show tabbar.
[self.tabBarController hideTabBarAnimated:YES];
[self.tabBarController showTabBarAnimated:YES];
Hope this Helps.
Hope this works.

Here is my solution (my tab view controller is inside navigation controller for good measure)... So I have subclassed UITabBarController and did this... exposing -setTabBarHidden: method
- (void)setTabBarHidden:(BOOL)hidden {
_tabBarHidden = hidden;
[UIView performWithoutAnimation:^{
[self adjustViews];
}];
}
- (void)adjustViews {
if ( _tabBarHidden ) {
CGRect f = self.tabBar.frame;
// move tab bar offscreen
f.origin.y = CGRectGetMaxY(self.view.frame);
self.tabBar.frame = f;
// adjust current view frame
self.selectedViewController.view.frame = self.view.frame;
} else {
CGRect f = self.tabBar.frame;
// move tab bar on screen
f.origin.y = CGRectGetMaxY(self.view.frame) - (CGRectGetMaxY(self.tabBar.bounds) + CGRectGetMaxY(self.navigationController.navigationBar.frame));
self.tabBar.frame = f;
// adjust current view frame
f = self.view.bounds;
f.size.height -= CGRectGetMaxY(self.tabBar.bounds);
self.selectedViewController.view.frame = f;
}
}
- (void)viewWillLayoutSubviews {
[super viewWillLayoutSubviews];
[UIView performWithoutAnimation:^{
[self adjustViews];
}];
}
- (void)viewDidLayoutSubviews {
[super viewDidLayoutSubviews];
[UIView performWithoutAnimation:^{
[self adjustViews];
}];
}
put the statement in the init method of the UIViewController
override init(nibName nibNameOrNil: String?, bundle nibBundleOrNil: Bundle?) {
super.init(nibName: nibNameOrNil, bundle: nibBundleOrNil)
self.hidesBottomBarWhenPushed = true
setupDependencyConfigurator()
}
See this thread:
Show/Hide TabBarController in iphone
In summary, you can see an example of this behavior in this sample code:
http://developer.apple.com/iphone/library/samplecode/TheElements/index.html
Why are you not using a navigation controller. It's a lot easier to hide the nav bar than the tab bar...
Just made the following code in Monotouch inside a subclass of UITabBarController:
public void ShowTabBar()
{
UIView.BeginAnimations("Anim");
UIView.SetAnimationDuration(0.25f);
this.View.Subviews[0].Frame = new RectangleF(0f, 0f, 320f, 431f);
this.TabBar.Frame = new RectangleF(0f, 431f, 320f, 49f);
this.TabBar.Hidden = false;
UIView.CommitAnimations();
}
public void HideTabBar()
{
UIView.BeginAnimations("Anim");
UIView.SetAnimationDuration(0.25f);
this.View.Subviews[0].Frame = new RectangleF(0f, 0f, 320f, 480f);
this.TabBar.Frame = new RectangleF(0f, 481f, 320f, 510f);
this.TabBar.Hidden = true;
UIView.CommitAnimations();
}
