xcode unable to hide tabbarcontroller - objective-c

Question

I have a tabbarcontroller as main controller and when a view is pushed I would like to hide it. I use hidesBottomBarWhenPushed but not working. Thanks.
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
if (self) {
self.hidesBottomBarWhenPushed = YES;
}
return self;
}

Answer 1

try to add this line when you push this controller, in it's parent view controller :
YourViewController *controller = [[YourViewController alloc]init....];
controller.hidesBottomBarWhenPushed = YES;
//then push the view controller
Good Luck

Answer 2

This will only work if one of the viewControllers of the tabBarController is a UINavigationController. The hidesBottomBarWhenPushed property is only respected if a view controller is pushed onto the stack of a UINavigationController and will not do much if it is the root view controller.

I've implemented my own custom tabBarController (which extends the original UITabBarController), because I need to toggle bars programmatically under certain circumstances (like device rotation), this is my implementation (comments explain how it works):
- (void)hideBottomBar:(BOOL)hide
{
#try
{
// UITabBarController has 2 subviews:
// - the first (index:0) is that one containing the active view controller's view
// - the second (index:1) is that one containing the UITabBar (self.tabBar)
UIView *topView = [self.view.subviews objectAtIndex:0];
UIView *bottomView = [self.view.subviews objectAtIndex:1];
// hide tabs container if necessary
[bottomView setHidden:hide];
// adjust frame
if (hide)
{
// expand main view to fit available space
[topView setFrame:self.view.bounds];
}
else
{
// restore main view frame
CGRect frame = topView.frame;
frame.size.height -= bottomView.frame.size.height;
[topView setFrame:frame];
}
}
#catch (NSException *exception)
{
[[GTMLogger sharedLogger] logError:#"Error occured adjusting tabs view: %#", exception.description];
}
}
