Question

I am trying to make a navigation based application having three UIViewController in navigation stack. I have a bottom bar (UITabBar).

I want to hide tabbar when first UIViewController is pushed into the stack and I want to show tabbar when second UIVIewController is pushed.

Here is the code I have written to do so.

For First UIVIewController:

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

For Second UIViewController I have done:

NotificationBO *obj=[self.notificationsArray objectAtIndex:indexPath.row];
object.hidesBottomBarWhenPushed = NO;
[self.navigationController pushViewController:object animated:YES];
[object release];

Now the problem is that, I can get UITabBar Hidden for first UIViewController, but for second it is also hidden.

How can I solve this issue?

Instead of using hidesBottomBarWhenPushed method. Try your code for hiding tabbar in your ViewController, like

[self.tabBarController.tabBar setHidden:YES];

and for showing tabbar

[self.tabBarController.tabBar setHidden:NO];

The above one will work, but the problem is it’ll leave an empty space in viewController bottom. To overcome this, set frame to your tabbarController.

For Hiding, set

[self.tabBarController.tabBar setFrame:CGRectMake(0, 480, 320, 50)]

For Showing, set

[self.tabBarController.tabBar setFrame:CGRectMake(0, 430, 320, 50)]
