When using hidesBottomBarWhenPushed, i want the tab bar to reappear when i push another view

Question

I have a navigation controller. For one of the views i want to hide the bottom tab bar, so it gets the max possible screen real estate. To do this, i have:

- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil {
    self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
    if (self) {
        self.hidesBottomBarWhenPushed = YES; // To hide the tab bar
    }
    return self;
}

But for the next view that i push on the stack, i want the tab bar to reappear. Is there a way to do this?

As of iOS5, there's a very easy means of accomplishing this. It's essentially the same method as Deepak, but there aren't any artifacts with the animation - everything looks as expected.

On init, set

self.hidesBottomBarWhenPushed = YES;

just as you have above. When it's time to push the new controller on the stack, it's as simple as:

self.hidesBottomBarWhenPushed = NO;

UIViewController *controller = [[[BBListingController alloc] init] autorelease];
[self.navigationController pushViewController:controller];

self.hidesBottomBarWhenPushed = YES;

It's important to reset the value to YES after the controller has been pushed in order to re-hide the bar when the user taps the Back button and the view comes back into view.
