Hi All,
I have a very simple IOS app that has 2 tabs currently.
When on the first tab, using NavigationViews, i can be 3/4 views deep.
When i click tap tab 2 and then back to tab 1 i am not where i was on view 4 but back to view 1 of that tab.
Could someone please explain how i would go about making sure that the user goes back to where they were rather than back to view 1.
Help is always appreciated.
Kind Regards
Adam
Normally, tab should retain its context.

I have tested on a simple app:
- initial view is a tabBarController
- In this, 3 tabs leading to FirstView, SecondView, ThirdView, each with simply a label to see where we are
- Then, I embed each of those in a NavController
- I add new views: FirstView2, SecondView2, ThirdView2
- In FirstView, add a next button to segue to FirstView2 with a show segue
- idem in SecondView and ThirdView
Then I tested:
- open app
Opens on FirstView
- click Tab 2
I see secondView
- click Tab 1: return to FirstView
Now to test state preservation
- Click next in FirstView
- shows FirstView2, with a back button at top and tabbar at bottom
- click Tab 2
I see secondView again
- click next: I see SecondView2
- click Tab 1: go to FirstView2
So, state was preserved
- click Tab 2: go to SecondView2
So, state was preserved
- click Tab 3: go to ThirdView
What is different in your setup ? How do you navigate from FirstView to FirstView2 ?
Normally, you have nothing to do more to retain the state.
If you cannot get it work, you may need to keep in a var the last view where you were in a tab.
And navigate to that view when you click tab again.
You will have to set a storyboard ID for each of the VC in navigation stack.
Have a look here to navigate programmatically.
But the best would first be to understand why it does nopt work as it should.
