HidesBottomBarWhenPushed, but when pressed

I have a problem with something that seems very simple. My application has a view hierarchy consisting of a UITabBarController containing UINavigationControllers. When I move from the root to the second level I set hidesBottomBarWhenPushed to true so that the tab bar is hidden.

On my firstLevelController:

[secondLevelController setHidesBottomBarWhenPushed:YES]; [self.navigationController pushViewController:secondLevelController animated:YES];

After that, when I click on the third level, I again bring up the tab bar, running in the second LevelController:

 [self setHidesBottomBarWhenPushed:NO]; [thirdLevelController setHidesBottomBarWhenPushed:NO]; [self.navigationController pushViewController:thirdLevelController animated:YES];

(I know I didn't like it either [self setHidesBottomBarWhenPushed:NO] , but it didn't work otherwise ...)

So here is the problem: when I click the back button on the third level and the second view appears, I need to hide the panel again, but I could not find a way to do this.

Any help is appreciated

This is what works for me.

 [self setHidesBottomBarWhenPushed:NO]; [thirdLevelController setHidesBottomBarWhenPushed:NO]; [self.navigationController pushViewController:thirdLevelController animated:YES]; [self setHidesBottomBarWhenPushed:YES];

Third level The controller shows the tab, and the second Level Controller does not show tabs when you pop out the third Level Controller.

On your second controller, do:

 - (BOOL) hidesBottomBarWhenPushed { return ([self.navigationController.viewControllers lastObject] == self); }

Thus, the tab will always be hidden if you are on the second controller, and it will appear on other view controllers

You can save the bool value to see if you are coming from a popViewController and in viewDidAppear you may find that it hides your tab bar again.

 - (void)viewDidAppear:(BOOL)animated { [super viewDidAppear:animated]; if(backFromThirdView) [self setHidesBottomBarWhenPushed:YES]; else [self setHidesBottomBarWhenPushed:YES];

}

I had the same problem. I always tried to hide the tab when selecting a row and disable hiding after returning to the list (tabular view inside the navigation controller) so that the user can select the menu again. I installed tabbarcontroller hidden inside the method

 -(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath{

but when I hid it inside this method, Tabbar was still hiding when it returned to my list. Now I hide the Tabbarcontroller inside the init method of the specific view manager, maybe this works for someone else too:

 - (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil{ self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil]; if (self) { // Custom initialization } [self setHidesBottomBarWhenPushed:YES]; return self; }

Now, when I select a list item, and this view manager will be presented, the timebar is hidden, after returning to the list it appears again.

You can try this

You declare in the second LevelController

 static BOOL bottomBarShouldHide = YES;

In viewDidLoad

 if (bottomBarShouldHide) { [secondLevelController setHidesBottomBarWhenPushed:YES]; bottomBarShouldHide = NO; } else { [secondLevelController setHidesBottomBarWhenPushed:NO]; bottomBarShouldHide = YES; }

Hope this helps you.
