Good day! I wanted to implement navigation in my app with flow_builder package. I have bottom navigation bar with several tabs in it and inside each of the tab's route I have several nested routes. I have made a small example application and I have a problem with tab transitions, namely if you navigate to a route within a tab and try to change tab again the navigation stack changes very strangely. Am I using this package properly and is it even possible to implement such navigation with it? My sample app
[Edit]
I have nested FlowBuilder() inside each tab and now everything seems to work fine. However, I am not sure whether it is appropriate solution.

I am working on a mobile version for my company's web app. The structure of this application requires uitableviews with a tab bar on the bottom and a navigation bar up top to return to the previous view. As you drill down in the application the tab bar items change at each level allowing selection of different views pertaining to that specific level in the app. I need a way to implement this with a navigation bar on top that navigates back to the previous screen on every tab in said tab bar when a back button is clicked on any of the tabs.
for example: let's say i start out with an items tab and a simple about tab. When i click items it drills down to a new view called subitems and the tabs for this view are subitems, favorites, details, and notes. I want the navigation bar to go back to the previous screen when i click the back button on any one of these four tabs.
Is this at all possible? I can't seem to find anything related to this type of structuring within an app. any help/examples would be greatly appreciated.
I know that a negative answer always sounds bad, but I tried to do the same a few months ago and I could not find a way of doing it using the standard UITabBarController/UITabBar. Take also a look at this question/answer.
The good news is that it is not that difficult to implement from scratch a tab bar controller that can be pushed on a navigation stack. There are also several examples around, one is BCTabBarController. GtabBar is another example.
I actually found a way to do it you just have to implement the navigation bar's leftbarbuttonitem instead of the traditional back button. Then I just created a method that is invoked when the back button is pushed this updates the navigation stacks of all four views within the tab bar and sets the tab bar items accordingly to match with the previous views we are navigating back to. . . so long story short...it is possible.
I am working on a project which involves both kind of applications ie Navigation based and Tab based. All things are working perfectly. But what I want is, when I click on a particular tab then a button must be added to the navigation bar at the top to edit the table below it. I am able to draw the button but it is not affecting the tableview below it. When I do this in navigation based application it works perfectly. But it does not work in tab based.
So please tell me the way to add button at navigation bar in UI tab based application which appear only at particular tab.
tell me the sample code or any tutorial for it.
For each tab embed a UINavigationConrtoller, and your own view controllers in them.
This way each tab will have its own navigation bar, and thus can have their own sets of bar items, titles, etc.
You generally never want to embed a UITabBarController in a UINavigationController, always the other way around.
I have an application that seems best suited for a navigation controller. There are a few places where navigation splits off and is not completely hierarchical but I think I can remedy that just using a modal view at those points.
I want to know if this is the best way to navigate through multiple views or if there is a better way. I want the user to be able to progress through several steps but be able to go back a step or even return to the beginning at certain points.
Additionally, I want to be able to do this using custom buttons. I want to use the entire screen without any navigation bars, etc. I figured I could push and pop the stack with my own custom buttons but I want to know how to make sure the screen is totally usable by me.
As far as I know, Navigation controller is the best way to navigate among views, you can go back and forth between views using navigation controller easily, even you can present navigation controller as modal view. You can specify your own custom navigation items in navigation bar. And if you do not want navigation bar, you can hide navigation bar. pushing and popping is the best way to implement navigation among views.

I have been in that situation!
Here's what I'd do:
"Hide the navigation bar" using the setHidden property. At places where you want the navigation bar to be seen, I suggest you use a UIToolbar with custom buttons. (its almost impossible to differentiate)
to go back one step you can popViewController
to go all the way back you can use popToRootViewController (like the top right corner button in the IMDB app)
There is no reason why you should not be able to use a navigation controller without using the navigation bar.
Hope this helps!
Keep the nav controller, but you can hide the nav bar easily enough. It could be a viable solution, but make sure your implementation is solid and clear; otherwise you may be rejected. A possible alternative would be to have pages side by side, as in the weather app…but it's your decision as to which paradigm is best.
I've been able to incorporate all of Apple's code, delegation, etc related to iAds, in simple view based applications.
Tab bar type applications seem more difficult, perhaps I don't understand the overall architecture of those apps. It seems that, say, if there are 3 tabs and views corresponding to those tabs that the other tabs sort of inherit or are attached to the first tab.
When working in interface builder, it seems that dragging an adbanner into the windows actually replaces everything that is there and building some kind of view container to put the "tab infrastructure and associated views" and an iad doesn't seem to fly.
I'm able to code by hand the pop of an ad in my code, which shows up when running the app under the first tab, but it doesn't show on the subsequent tabs, I was doing this in viewDidLoad. It seems the tab bar apps want to sort of own the entire screen realestate to some extent. Any thoughts? There's a UIWindow and the TabBarController, the window seems largely "blank" and otherwise purposeless.
What I would do is create a separate custom view, which you push onto your enclosed view in each tab just as part of the viewDidLoad process.
I'm curious what the best method is for managing the traversal through several views without burning screen space using a navigation bar.
As an example, assume I have four UIView's with associated UIViewController's:
1: Top level menu (invokes A or B.1)
1.A: Menu selection A (return to 1)
1.B.1: Menu selection B, part 1 (invokes B.2)
1.B.2: Menu selection B, part 2 (return to A)
First, I'm unsure if a navigation controller is appropriate when I am not using a navigation bar. As an alternative, I am considering implementing a custom UIViewController that holds view controllers and acts as a screen manager.
Thoughts?
You can always hide the navigation bar using setNavigationBarHidden:animated:
Other than that it depends on what type of app you are building. Yours sounds like something that could use a Tab Bar, although that doesn't solve your problem of taking up screen space.
XCode's templates offer another way to do it - try looking at a new project that is a "Utility" app. It shows how you can seamlessly switch between a couple of different screens.
