Question

I have View with MKMapView:

- (void)viewDidLoad
{
   [super viewDidLoad]; 
   self.navigationController.toolbarHidden = NO;

   /* code of MKMapView ...*/
}

- (void)viewWillDisappear:(BOOL)animated
{
   self.navigationController.toolbarHidden = YES;
}

and when I get out from this view, for a few seconds instead toolBar I see black stripe! What is this??

Answer 1

Perhaps you may try

 [self.navigationController setHidden:Yes animated:Yes];

If that doesn’t do it, move the call out of this view controller. Move it to the viewWillAppear: method of the view controller that you are moving to like so

- (void)viewWillAppear:(BOOL)animated
{
    [super viewWillAppear:animated];

    [self.navigationController setToolbarHidden:Yes animated:animated];
}

This is how I have my own and it works.
