I have a tab controller in which five viewControllers are there. I even have a side menu bar which has the list of other viewControllers . My problem is when i try to click any list to move to viewController it get pushed over the screen, hiding the tab bar at the bottom. How can i show the tab bar at bottom for this scenario. I got some ideas but it dint helped.
You need to make sure that your tab bar controller is you root view controller.
Your story board should look like
tabbarController -> NavigationController -> VC1 -> VC2
Your VC1 to VC2 segue has to be a show segue, not a present modally because the second one makes V2 the root view controller.

In the bottom left viewcontroller i have a searchbar at the top that call the tableview at the top , the problem is that i want to segue to the right viewcontroller with detail of it, but of course i'm losing my navigationController so when i'm into the right viewcontroller i can't go back anymore, how should i do to go back to my original Viewcontroller ?
Add Navigation Controller as the starting view in storyboard. And then Link RootViewController to it. This will ensure navigation bar in all the views coming next.
you may hide navigation bar in the view where not needed as
self.navigationController?.isNavigationBarHidden = true
push newViewController instead of presenting
Also please check, if you are presenting it modally. Modal segues take over the whole screen, so any navigation bars, tool bars, or tab bars that are in the presenting controller will be covered up. If you want a navigation bar on this modal controller, you'll need to add one specifically to it, and add any buttons you want to that new navigation bar (or tool bar). If you don't want to do this, then don't present it modally, do a push to it.
I'm trying to setup back button on the navigation controller but it doesn't appear when I run it. I watched some tutorials and it usually works.
Your flow should be:
NavigationController --> MainVC --> FoodVC
Now you can add button as follow:
Navigation Item -> Left Bar Button Items -> Bar Button Item -> back button
Go to navigation controller scene -> navigation controller ->navigation bar - then go to right top show attributes option and change bar tint color.Try it
The view controller food is embedded in Navigation Controller , hence it is root view controller.
Navigation bar will appear when any viewController is push on same navigation controller.
So, If you tableview is already in Navigationcontroller then remove Navigation Controller in which Your FoodVC Controller is embedded.
If you want that navigation controller, you may add leftBarButtonItem programatically.
Totally depends on your requirement.
Is MenuVc your main Controller? try this, delete that navigation controller in the middle. Then click the MenuVc, embed in Navigation Controller and set the navigation controller as initial view controller at the attribute inspector. then navigate the menuVC to Food, "Show".
I've got 3 view controllers. Two I have hooked up to a tab bar controller and one that I'm wanting to access when a user selects a cell on the second view controller in my tabbed views.
I'm wanting when the user hits "back" on the 3rd "detail" page for the user to be taken back to the 2nd view.
When I do this by just adding a button and segueing back to the 2nd VC, the tab bar is gone. I tried in my viewDidAppear to unhide the tab bar, but I guess going off of the tab bar controller messes up the navigation.
I tried creating a variable that was like "didHitBack" and on my "back" button on the 3rd view I'm creating a segue back to the Tab Bar Controller, and if "didHitBack" is true I do
_ self.tabBarController?.selectedIndex = 1
which takes me to the second page, but it's loading the first view in then going to the second page which looks bad.
I was thinking maybe there was a way to do "didHitBack" and setting the tab bar's initial view controller to the second one or something, but that all just seems very wrong.
Is there a "proper" way to do this?
To recap I have VC1 and VC2 that are hooked up to a Tab Bar Controller, I have a tableview on VC2 that on didSelectRow I'm going to VC3 which I do not want to be a part of the tabbed view controller, and when I hit back on VC3 I want to go back to VC2.
If you want to build a navigation stack, you should embed your view controller in a UINavigationController
So your tab bar would be hooked up to VC1 and NavVC. The root view controller of NavVC would be VC2.
You can then push a new view controller onto the stack using the navigation controller (or pop the view controller to go back) all within the confines of the tabBar.
I have a RootViewController which is a TabBarController which have 5 ChildViewControllers. Each child is a NavigationController. Each child will be able present a FullScreenController which have modalTransitionStyle set to OverFullScreen and present by calling showDetailViewController. The FullScreenController need to be able to further navigate which will push another ViewController into the current NavigationController.
The problem I am facing is that the FullScreenController is presented by the TabBarController, and I cant present the original TabBarController again since it is the PresentingViewController of the FullScreenController.
Anyone know how to properly support a ViewController hierarchy with the following requirements
Should support a navigation bar and a tab bar
Should be able to present a FullScreenController which don't have navigation bar and tab bar
The FullScreenController can navigate to another ViewController which have both navigation bar and tab bar
Should support navigate backward
Each tab on the tab bar represent its own navigation stack
You can add full screen view as child controller to Each Tab bar controller and keep the close button from full screen view (close will take them back to tab bar view).
Hope this will help.
I'm trying to find out why any ViewController, that I push onto navigation stack does not show tabbar. Now I have construction like this:
loginVC -> navigationController -> SWRevealVC --> (leftPanelVC and second segue is to tabbarController, which has 4 its own view controllers). When I push view controller from any of this 4 controllers I'm loosing my tabbar and I cannot bring it back. Tried hidesBottomWhenPushed but it didn't work out as expected. Anybody?
EDIT:
What I just tried, was to set connections like this: login -> tabbarcontroller -> as first subcontroller I set up SWRevealViewController and hooked to it front navigationController and rear tableController. Unfortunately it messes stuff a bit, because tabbar now stays always, even on top of rear controller... the look I'm trying to get is interaction like in facebook app, where tabbar is always visible, but as a part of front controller, not overlaying rear.
When I push view controller from any of this 4 controllers I'm loosing my tabbar and I cannot bring it back.
I am not sure what you are doing here, but as far as I understand, you have:
pushed a tab bar controller on to a navigation controller;
from that tab bar controller, pushed a new view controller on to the navigation controller.
It that is correct, than it is normal that your tab bar controller tab bar "disappears" since you are pushing a new view controller (point 2) on to the navigation controller and this will replace the tab bar controller as the top most controller in your navigation controller.
Possibly, what you are looking for can be obtained by embedding a navigation controller inside of a tab bar controller, but I do not have enough info about your UI to be sure this makes sense.
