Suppose I have 3 tabs on tab bar controller:
TabAViewController
TabBViewController
TabCViewController
and in tab C I have one button.
When I click on that button then open the another View (CsubViewController which is not TabAViewController, TabBViewController, TabCViewController). How to call that Another View (CsubViewController) on button click?
And how to come back to the same view after back button click.
It depends. If you are using a NavigationController as the root controller, you push the CSubViewController in your current ViewController by
navigationController.pushViewController(...)
and go back with
navigationController.popViewControllerAnimated(...)
which is the simplest way to achieve your goal.
Or you can write your own code and try to present the CSubViewController modally in traditional presentViewController(...) and dismissViewController way.

I have 4 tabs and in the home tab, I have a button to goto profile view controller.
When I use segue, The view changes completely and it's presented over tab bar. So it gets hidden.
I want to present it under the tab bar so that I can quickly navigate to other tabs without a back button.
I am not sure if this is the right way or not. but you can add presenting viewcontroller's view as subview with the same animation.
I have tab bar controller with 3 tabs(all view controllers are embedded in navigation controller) while clicking the 3rd tab am showing a view controller with start button, clicking start it goes to the next controller, from this controller by programmatically am pushing to another vc. Now my issue is when I click the 3rd tab it showing the last pushed controller instead of showing a view controller with start button.
If I double click the 3rd tab it showing the current view controller.
Help much appreciated.
That’s how it is supposed to work, if you want to show the root vc for tab 3 you’ll need to call popToRootViewController() on the navigationController.
aVC.navigationController.popToRootViewController()
You would need to call the above when the relevant tab button is tapped, so you can use UITabBarControllerDelegate to find out when that happens.
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 would like to introduce in my app a View that will contains both navigation bar and a tab bar at the bottom. View contains a Table View with multiple entries and once user tap on a cell a push segue takes him to another view with details regarding the cell he has previously tapped. If he decides, user can go back to parent view by tapping on 'Back' button of the navigation bar on top. In addition to this, I would like my view to have a tab bar at the bottom with extra tools for the user. So, if he decides to check the 'Creator' of the app, he can by simply tap on 'Creator' TabBarItem at the bottom.
I would like to ask you what is the best way to achieve the above. I have already tried to use UITabBarController combined with UINavigationController. Didn't achieve what I was looking for because I would like the view with the table on it to be independent from the TabBarController and NOT a part of it (by part I mean by accessible through tabs).
Do you believe a UINavigationController view with UITabBarView would be a better choice?
UPDATE
What I mean by, "independent from the TabBarController and NOT a part of it":
Once the app loaded, I would like to see my main view (with table) contains Navigation Bar on top and Tab Bar at the bottom. However, I don't want to see the first tab of the Tab Bar selected because my main view will not be accessible through tabs of the Tab Bar but through Navigation Bar. If, for example, I am in Main view and tap on 1st tap, I would like to move to another view that will contains some other info.
Option 1:-
Create a tab bar Controller and on that TabbarController assign your navigation Views.
say nav1 with tab1 , nav2 with tab2...
Option 2:-
Create a Navigation View Controller and than add the tabbarcontroller on that navigationView Controller by using addSubView.
So when the user clicks on a row in a table u will go to a different View which doesn't have the TabbarController and when the user comes back he will again see the TabbarController.
This is what I will do:
First I will subclass UITabbarController and create for example ParentTabBarController. This controller will contain all the tabs necessary and what they will do if they are clicked so on.
Next for each viewcontroller I create, I will subclass from this ParentTabBarController so that the tabs are already in. You can add additional functionality or override it depending on your situation.
In your appdelegate pass in a navigation controller and every time push and dismiss the viewcontrollers you created in second step.
Hope this helps..
I am very new to Xcode and have encountered an issue with my app. I am trying to create a tab bar app. On one of the tabs I have a button that brings the user to a different ViewController. I want to have it so the user can select a button that would return them to the tab that had the button. I tried to set up an action from the button to the previous view (the tabbed screen), however the tab bar disappears. I hope this is makes sense.
Here is a link to a screenshot...
Easiest way to do this is to place a UINavigationController as the root view controller of the TabBarController. You can do this in storyboard by simply ctrl+dragging from the tabbar controller to the navigation controller and adding it as a relationship.
Here's an example using storyboards:
The next step is to set the third controller (in this case the table view controller) to your player view controller class.
Then, you can use the default back button and animation that comes with the navigation controller. If you prefer to hide the navigation bar at the top of the screen, then you can use your custom back button to call
[self.navigationController popViewControllerAnimated:YES];
You can also choose custom animations / segues, etc. but using a navigation controller to help you navigate screens is probably the simplest approach.
