How to hide/show tab bar of a view with a navigation bar in iOS?

I have views with a navigation bar and a tab bar. What I would like to happen is to hide the tab bar on a certain view and show the tab bar again when the user changes views.

I saw a snippet of code for hiding the tab bar:

-(void)makeTabBarHidden:(BOOL)hide
{
    // Custom code to hide TabBar
    if ( [tabBarController.view.subviews count] < 2 ) {
        return;
    }

    UIView *contentView;

    if ( [[tabBarController.view.subviews objectAtIndex:0] isKindOfClass:[UITabBar class]] ) {
        contentView = [tabBarController.view.subviews objectAtIndex:1];
    } else {
        contentView = [tabBarController.view.subviews objectAtIndex:0];
    }

    if (hide) {
        contentView.frame = tabBarController.view.bounds;       
    }
    else {
        contentView.frame = CGRectMake(tabBarController.view.bounds.origin.x,
             tabBarController.view.bounds.origin.y,
             tabBarController.view.bounds.size.width,
             tabBarController.view.bounds.size.height - tabBarController.tabBar.frame.size.height);
    }

    tabBarController.tabBar.hidden = hide;
}

from: http://nickwaynik.com/iphone/hide-tabbar-in-an-ios-app/

I call this on the view wherein I want the tab bar hidden

[self makeTabBarHidden:YES];

it works fine when i show/hide it on that view but when I navigate back to the previous view, the tab bar there is also hidden. I tried calling that function in the view's viewDidUnload, viewWillDisappear, viewDidDisappear functions but nothing happens. The same is true when the function is called in the previous view's viewDidLoad, viewWillAppear, viewDidAppear functions.

Try this for hide / show:

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

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

self.navigationController.hidesBottomBarWhenPushed=YES;

Add this line to your viewDidLoad or viewWillAppear; this will hide you tab from bottom.

you can use below code but tabBar remains hidden when you navigate back.

    //hide tabbar
    //self.tabBarController?.tabBar.isHidden = true

better way is to do through main.storyboard check "Hide Bottom Bar on Push" as I've done.

You can also do this in the Interface Builder for a storyboard. Select the View Controller that you want to hide the Tab Bar for and then select "Hide Bottom Bar on Push".

I just created a category on UITabBarController that allows you to hide the TabBar, optionally with an animation:

https://github.com/idevsoftware/Cocoa-Touch-Additions/tree/master/UITabBarController_setHidden

It adds the tabBarHidden property (with isTabBarHidden as its getter) and the - (void)setTabBarHidden:(BOOL)hidden animated:(BOOL)animated method.

The same property is available on the attributes inspector when you click on your view controller on your Xib or storyboard file.

You can set the UIViewController.hidesBottomBarWhenPushed instead:

DetailViewController *detailViewController = [[DetailViewController alloc] init];
detailViewController.hidesBottomBarWhenPushed = YES;
[[self navigationController] pushViewController:detailViewController animated:YES];    
[detailViewController release];
