I have a tabbar controller with 3 tabs, each tab has navigation controller, on root view controller of each navigation controller i want tabbar and on other view controller in same navigation controller i dont want tabbar.
Any solution?
set self.tabBarController?.tabBar.isHidden = true in viewWillAppear method of your controller when you don't want tabbar
override func viewWillAppear(_ animated: Bool) {
self.tabBarController?.tabBar.isHidden = true
}
Setting alpha value 0 to tab Bar hides all items and including tab bar
You should set the tabbar alpha to 0. This will hide the UITabBar.
However you need to set isUserInteractionEnabled to false since even when its hided, the buttons are there & clickable still!
Hope this helps!
Set Transculent property of Tab bar to true or check the same from storyboard
Set hidesTabbarWhen Pushed property of Tab bar to true or check the same from storyboard
Set Tab bar hidden true on view controller where you want Tab bar and set Tab bar hidden to false on view controller where you don't want Tab bar

In my application, I hide tabbar by setting hidesBottomBarWhenPushed property of UIViewController. I'm not sure this behavior is designed or not, when I called popToRootViewController to pop all view controller stack, tabbar did not show properly if I pushed same view controller after. Even I tried to show tabbar by setting isHidden property after I called popToRootViewController but it didn't work neither. Weird part is, after tabbar disappeared, I pushed same view controller and I could see the tabbar when I tried to pop the view controller (not popToRootViewController) by using gesture to pop (swipe to pop). Though it disappeared when transition was completed.
FYI, this is step by step to produce this behavior.
init tabbar and navigation controllers on two tabs.
push view controller (hidesBottomBarWhenPushed is true) on one tab's navigation controller
pop all view controller from the navigation controller by calling popToRootViewController
4 change tab index by setting selectedIndex on tabbarController
push the same view controller
How does hidesBottomBarWhenPushed property work in detail to show/hide tabbar?
I'll talk about the problem in my app.
For every pages, I'll edit the self.navigationController?.navigationBar.isHidden and self.tabBarController?.tabBar.isHidden = false to guarantee the state of tabBar and navigationBar in the viewWillAppear.
Sample
// In this viewController, I'll show the navigation bar and hide tab bar
override func viewWillAppear(_ animated: Bool) {
super.viewWillAppear(animated)
self.navigationController?.navigationBar.isHidden = false
self.tabBarController?.tabBar.isHidden = true
}
The navigationBar and tabBar can keep their state from last view controller when you push a new one or pop a old one. So it will let we set in every view controller to control and ensure its state as I wish.
How can I hide my left bar button item?
In my storyboard I dragged a Navigation Bar onto my View Controller, then a Bar Button Item. Under certain conditions I want to hide the Bar Button Item.
None of this works:
override func viewDidLoad() {
self.navigationItem.leftBarButtonItem = nil
self.navigationItem.leftBarButtonItems = []
self.navigationItem.setLeftBarButtonItems([], animated: true)
}
I dragged a Navigation Bar onto my View Controller
Well, don't! There is a big difference between a navigation controller interface, where you set the navigationItem, and a loosey-goosey navigation bar just sitting there in the interface, which is what you have.
Embed your view controller in a UINavigationController and do things the right way. Then setting your navigationItem and its properties will work as expected.
You can't access to self.navigationItem.leftBarButtonItem because you manually drag navigationBar from storyboard. I would suggest to do the following instead:
add an IBOutlet of BarButtonItem (eg: barButton) that you created in storyboard
barButton.title = ""
barButton.isEnable = false
This will hide your BarButtonItem, and you can simply show it back later.
I have used the 'Embed In' navigation controller within the storyboard. Is there a way to completely disable the whole navigation bar? I have tried the code below, but when there is a swipe, the navigation bar appears again. I want to be able to completely hide the whole bar until a condition is met. Is there a way to do this?
self.navigationController?.hidesBarsOnSwipe = true
self.navigationController?.hidesBarsOnTap = true
I have tried a custom navigation bar, but I couldn't get a nice scroll effect like with the default navigation bar.
To hide the navigationBar just do:
self.navigationController?.navigationBar.isHidden = true
Add this row in your viewDidLoad.
You can use this in viewDidLoad:
self.navigationController?.setNavigationBarHidden(true, animated: false)
I currently have a viewcontroller that has two navigation bars because Its has a navigation controller both before and after a tab bar controller. I tried to have it so that the viewcontroller before the tab bar controller will present modally but by dong so the 2nd nav bar didn't work properly. The 2nd nav bar is a custom side menu that only appears to work if the first navigation controller is preset. Here is a pic
Is there a way so that only the bottom nav controller is visible?
If I understand your question correctly, you want to hide the ui for the enclosing navigation controller - i.e. the nav bar. You can do that by setting it hidden in the viewDidLoad() function of that view controller:
override func viewDidLoad() {
super.viewDidLoad()
navigationController?.setNavigationBarHidden(true, animated: false)
}
When I dismiss viewcontroller Navigation bar overlaps with status bar how to solve this issue ?
self.navigationController?.navigationBarHidden = true
add this code in your first view Controller
