Iphone Hide Navigation Bar Only on First Page

iPhone hide Navigation Bar only on first page

The nicest solution I have found is to do the following in the first view controller.

Objective-C

- (void)viewWillAppear:(BOOL)animated {
    [self.navigationController setNavigationBarHidden:YES animated:animated];
    [super viewWillAppear:animated];
}

- (void)viewWillDisappear:(BOOL)animated {
    [self.navigationController setNavigationBarHidden:NO animated:animated];
    [super viewWillDisappear:animated];
}

Swift

override func viewWillAppear(_ animated: Bool) {
    self.navigationController?.setNavigationBarHidden(true, animated: animated)
    super.viewWillAppear(animated)
}

override func viewWillDisappear(_ animated: Bool) {
    self.navigationController?.setNavigationBarHidden(false, animated: animated)
    super.viewWillDisappear(animated)
} 

This will cause the navigation bar to animate in from the left (together with the next view) when you push the next UIViewController on the stack, and animate away to the left (together with the old view), when you press the back button on the UINavigationBar.

Please note also that these are not delegate methods, you are overriding UIViewController's implementation of these methods, and according to the documentation you must call the super's implementation somewhere in your implementation.

iOS - Cannot hide navigation bar on first page

First of all,I will go to solve your problem.And then I will state about UINavigationController.

So you use SB create some viewControllers in Main.storyboard.These viewControllers must should inherit UITabBarController,UINavigationController or ViewController.
I see your screenshoot that is right，otherwise your screenshoot is unclearly.

If you want to edit or layout view,you need to create ViewController and match this ViewController with in Main.storyBoard.I will test these operation.you will can this.

And then these ViewControllers inherit match ViewController.

HomeTabBarViewController

FirstViewController

SecondViewController

As mentioned above,that is very clearly. if you want to hiddn navigationBar in this first page,you must handwritten code in FirstViewController.Also you operate in viewWillAppear:

self.navigationController.navigationBar.hidden = YES;

that's all.

If you handwritten code hidden navigationBar in HomeTabBarViewController inherit UITabBarController,because navigationController is next ViewController that is not work in hidden code.

So UINavigationController have auto create navigation bar.You want to not show this navigation bar to use hidden navigation bar in viewWillAppear.And also you want to hidden this page and next page show,you can this viewWillAppear to hidden,viewWillDisAppear to show.

I wish can help you for resolve problem.

iOS - Hide navigation bar only on one view?

Add this:

- (void)viewWillDisappear:(BOOL)animated {
    [super viewWillDisappear:animated];
    [self.navigationController setNavigationBarHidden:NO animated:animated];
}

iOS: Hide the navigation bar for only one viewcontroller which is root of the UINavigationController?

I got the another way to hide/show navigationbar from one of my friend.

• Set a delegate for the NavigationController:

navigationController.delegate = self

• Hide/Show navigationbar for each ViewController all in one place

func navigationController(_ navigationController: UINavigationController, willShow viewController: UIViewController, animated: Bool) {
    let hide = (viewController is YourVC)
    navigationController.setNavigationBarHidden(hide, animated: animated)
}

Navigation bar show/hide

This isn't something that can fit into a few lines of code, but this is one approach that might work for you.

To hide the navigation bar:

[[self navigationController] setNavigationBarHidden:YES animated:YES];

To show it:

[[self navigationController] setNavigationBarHidden:NO animated:YES];

Documentation for this method is available here.

To listen for a "double click" or double-tap, subclass UIView and make an instance of that subclass your view controller's view property.

In the view subclass, override its -touchesEnded:withEvent: method and count how many touches you get in a duration of time, by measuring the time between two consecutive taps, perhaps with CACurrentMediaTime(). Or test the result from [touch tapCount].

If you get two taps, your subclassed view issues an NSNotification that your view controller has registered to listen for.

When your view controller hears the notification, it fires a selector that either hides or shows the navigation bar using the aforementioned code, depending on the navigation bar's current visible state, accessed through reading the navigation bar's isHidden property.

EDIT

The part of my answer for handling tap events is probably useful back before iOS 3.1. The UIGestureRecognizer class is probably a better approach for handling double-taps, these days.

EDIT 2

The Swift way to hide the navigation bar is:

navigationController?.setNavigationBarHidden(true, animated: true)

To show it:

navigationController?.setNavigationBarHidden(false, animated: true)

How to hide a navigation bar from first ViewController in Swift?

If you know that all other views should have the bar visible, you could use viewWillDisappear to set it to visible again.

In Swift:

override func viewWillAppear(_ animated: Bool) {
    super.viewWillAppear(animated)
    navigationController?.setNavigationBarHidden(true, animated: animated)
}

override func viewWillDisappear(_ animated: Bool) {
    super.viewWillDisappear(animated)
    navigationController?.setNavigationBarHidden(false, animated: animated)
}
