How to hide UITabBarController programmatically?

Question

Is it possible to hide it with animation ?

Answer 1

A UITabBar inherits from UIView, so you can hide it and animate it like you would with a standard UIView.

- (void) hideTheTabBarWithAnimation:(BOOL) withAnimation {
    if (NO == withAnimation) {
        [theTabBar setHidden:YES];
    } else {
        [UIView beginAnimations:nil context:nil];
        [UIView setAnimationDelegate:nil];
        [UIView setAnimationDuration:0.75];

        [theTabBar setAlpha:0.0];       

        [UIView commitAnimations];
    }
}

Answer 2

You should use this code:

self.tabBarController.tabBar.hidden=YES;

Answer 3

-(void)hideTabBar
{   UITabBarController * tabbarcontroller= appDelegate.tabBarVC;
        if (tabbarcontroller.tabBar.isHidden) 
    {
        return;
    }
    tabbarcontroller.tabBar.hidden=YES;
    CGRect frm=tabbarcontroller.view.frame;
    frm.size.height += tabbarcontroller.tabBar.frame.size.height;
    tabbarcontroller.view.frame=frm;
}
-(void)showTabBar
{    UITabBarController * tabbarcontroller=appDelegate.tabBarVC;
    if (!tabbarcontroller.tabBar.isHidden)
    {
        return;
    }
    CGRect frm=tabbarcontroller.view.frame;
    frm.size.height -= tabbarcontroller.tabBar.frame.size.height;
    tabbarcontroller.view.frame=frm;
    tabbarcontroller.tabBar.hidden=NO;  
}
here appDelegate is = (AppDelegate *) [[UIApplication sharedApplication] delegate]
tabBarVc is UITabBarController *tabBarVC defined as property in app delegate
hope this helps

Answer 4

You can also hide it using the attributes inspector:

but not with an animation.
