I have a Bottom Navigation View with 5 Tabs and each tab has its own NavGraph. Lets assume I'm navigation with Tab1 through Fragment1 -> Fragment2 -> Fragment3
There is custom enter/exit transitions to each route (i.e. from Fragment1 -> Fragment2 -> Fragment3). Now I'm on Fragment3 and tap on Tab2 of Bottom Navigation View, it opens it own Graph of fragments flow => FragmentX -> FragmentY -> FragmentZ
Issue occurred when I tap on Tab1 again, the latest loaded Fragment3 in this TAB1 graph reloads its Enter transition.
Here is visual representation of scenario: Navigation Component + Bottom navigation view + Custom enter exit fragments transitions
I've tried multiple solutions, kindly get me out of this trouble.

I have HomeScreen with two tabs, SecondScreen and a ThirdScreen. I wish to navigate to second tab by clicking on the button located inside the ThirdScreen. How to achieve this?
Navigator.push gets me back to first tab, which is not what I want.
my navigation map in my app is somewhat like this: second tab -> SecondScreen -> ThirdScreen -> HomeScreen. how to go back to the tab i came from , from the third screen.
I added a toolbar with 2 items(A and B) to a window controller.
I'm trying to show a second view(B) on the same place as the first view(A) on a window controller.
I tried segue and it shows me a few options (sheet, show, custom, modal and popover). None does what I would like. The closest one was sheet.
For the first view I can see a relationship (window content to view controller) and it seems to be what I need.
The end result would be a preference window with toolbar to show different views. In some applications I see the window size changing, but it is not necessary.
After reading more and more, I did it by:
1 - Add a Tab View Controller
2 - Add image to each Tab View Item
3 - Change the style on Tab View Controller to Toolbar
When I build even the most basic default Tabbed Bar application in swift I have to click two times on the tab bar icon to change to the next view. How do I change this to only be a single click? It wasn't always this way, but now when I create any sort of tab bar controller it behaves like this.
I am using Xcode/Interface Builder/Swift to build a project. The project has a page view controller that allows the user to swipe left to right. This is the root view controller. On the first view controller that appears, I am placing a button on the bottom right hand corner. The problem is that the page view controller status icon, which is part of the PVC, is in front of the button, which is part of the first view controller.
How do I approach this issue? Does it matter that there are two view controllers involved with this issue?
I tried going to editor -> arrange -> bring to front. But that didn't help.
I have an app with three tabs that switch views instantaneously when the user taps them. The first view is a table view selecting which 'location type' to filter by, to only show those pins (add those annotations) to the second view, a MapView.
When a table cell is clicked, it switches instantaneously to the mapview, using this code:
self.tabBarController.selectedIndex=1;
However, I would like to do this with a slide-in-from-right animation, like the one you get when drilling down a hierarchy of table views.
I tried this:
[self.navigationController pushViewController:[self.tabBarController.viewControllers objectAtIndex:1] animated:YES];
which compiles without error or warning, but does not switch views.
How do I 'apply' a navigation controller 'onto' a tab bar controller? Or is there some way to select another viewcontroller and specify an animation?
I don't think you are going to be able to do that with a tab bar controller as there is no API to manage the animations. Your choices are either to swap out the tab bar and build something similar using buttons, in which case you can manage your own view stack, or to forgoe the animation and just switch views as you are doing.
An alternative approach is to display the map as part of the nav-controller stack belonging to your current tab - (assuming you have a nav controller stack) but that's not acutually going to swap tabs for you, just move you to a new place on your current stack.
