Question

Is it possible to put view (object) which will cover navigation bar? I simply can’t put it there. It allways hides under nav. bar.

Answer 1

You can do the following in the viewDidLoad of one of your viewControllers:

- (void)viewDidLoad 
{
    [super viewDidLoad];
    UIView* navigationBarCover = [[UIView alloc] initWithFrame:self.navigationController.navigationBar.frame];
    navigationBarCover.backgroundColor = [UIColor blackColor];
    [self.navigationController.view addSubview:navigationBarCover];
}

You can also hide the navigationBar and put the view on the viewControllers view:

- (void)viewDidLoad 
{
    [super viewDidLoad];
    [self.navigationController setNavigationBarHidden:YES animated:NO];
    UIView* navigationBarCover = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 320, 44)];
    navigationBarCover.backgroundColor = [UIColor redColor];
    [self.view addSubview:navigationBarCover];
}
