How to add a custom UIView to UINavigationBar in only one UIViewController

Question

Okay so I'm trying to add a subview to my navigationController's navigation bar, which works perfectly, however, when pushing a detail controller, I don't want that subview from the pushing controller to be seen in the detail view controller's navigation bar.

I appreciate any help/pointers offered. To restate: I need the subview to only be displayed in the root of the navigation controller, and to not be in any detail controllers.

Here's my current code for creating and adding the navigationController's subview:

- (void)viewDidLoad
{
    [super viewDidLoad];

    self.ImageView = [[UIImageView alloc]init];
    self.ImageView.frame = CGRectMake(0, 8.5, 320, 36);
    self.ImageView.contentMode = UIViewContentModeScaleAspectFit;
    self.ImageView.image = [UIImage imageNamed:@"Logo"];
    self.ImageView.clipsToBounds = YES;
    [self.navigationController.navigationBar addSubview:self.ImageView];
}

Answer 1

The best approach is to

1. Add a tag to your imageView.
2. Access your imageView using tag & set it's alpha to 1 in viewWillAppear of your mainViewcobtroller where you want to show this.
3. In new viewcontroller's viewWillAppear method, access the view with same tag & then set it's alpha to 0.

That's should solve your problem Should you need code, plz comment.

Answer 2

Perhaps you could tag the view, self.ImageView.tag = 100; Then in the detail controller's viewWillAppear:

 UIView view = (UIView *) [self.navigationControler.navigationBar viewWithTag:100];
 view.hidden = true;

and in viewWillDisappear

 UIView view = (UIView *) [self.navigationControler.navigationBar viewWithTag:100];
 view.hidden = false;

Answer 3

add this line when you push to otherViewControllers

 [[self.navigationController.navigationBar viewWithTag:101] removeFromSuperview];

recreate back from other viewController;

- (void)viewWillApper
{

    self.ImageView = [[UIImageView alloc]init];
    self.ImageView.frame = CGRectMake(0, 8.5, 320, 36);
    self.ImageView.contentMode = UIViewContentModeScaleAspectFit;
    self.ImageView.image = [UIImage imageNamed:@"Logo"];
    self.ImageView.clipsToBounds = YES;
    self.ImageView.tag =101;
    [self.navigationController.navigationBar addSubview:self.ImageView];
}

This will only affect the invoking view ocontroller:
In the Root viewcontroller of your navigationController

- (void) viewDidLoad {
        // Create / instantiate from Nib / Use already initialized UIView
        [self.navigationItem setTitleView:<your subView here>];
}

When you navigate to some other viewController, the subview won't be there.
