I have have a view controller that is embedded in a UINavigationController and I want to segue to another view controller that is also embedded in a different UINavigationController. If I try to use a push segue, I get an error saying that I can't push a UINavigationController. However, I don't think using a modal segue is appropriate. How should I go about this?
How should I go about this?
You should use a single navigation controller.
the problem is that I want different bar button items for each view controller and they won't change
Each view controller can set up the bar buttons however it likes. Take a look at UINavigationItem. Each view controller has a navigation item, and the navigation item has various properties such as leftBarButtonItems and rightBarButtonItems that you can use to set the buttons.

Back when I first created the foundational layout for the app I'm currently working on in Storyboard, I did it in two steps:
Selected my View Controller and used Editor->Embed In->Navigation Controller.
Selected my View Controller again and used Editor->Embed In->Tab Bar Controller.
This was the resulting layout:
Question 1: Why do these steps create such an odd layout?
In this weird layout that seems to imply that the Navigation Controller is attached to the Tab Bar Controller as its parent, the only way I can get navigation items to display in the app (in the view controlled by the View Controller on the right) is by placing them in the nav bar of the Tab Bar Controller scene.
However, this creates various issues, including not being able to create an IBOutlet in my View Controller file for a custom view I drag into the title view slot in the Tab Bar Controller scene. Meanwhile, dragging anything into the navigation bar in the View Controller scene just makes it not appear in the app when it runs.
Question 2: How can I fix this layout so that I can control-drag from navigation items into my View Controller file? Or is everything actually correct, and I'm just trying to force something I shouldn't? (My intention here is to be able to set the custom title view's text in my View Controller code.)
Its obvious, if you want to embed MyViewController to NavigationController then you need to change your second step and need to embed NavigationController to Tab Bar Controller.
Selected MyViewController and used Editor->Embed In->Navigation Controller.
Selected NavigationController Embed with MyViewController and used Editor->Embed In->Tab Bar Controller.
It should look like this.
Note: You need to embed MyViewController to navigationController only if you want to perform push operation on this TabBarItem means with MyViewController other wise simply embed MyViewController to TabBarController no need to embed it with NavigationController.
I have a problem with SWRevealViewController. In my app I have a long chain of UIViewControllers connected to a single UINavigationController. After adding a side menu and setting the "reveal view controller push controller" segue for cells I see only ViewControllers connected with a segue. I can't move between my UIViewControllers in the chain any more. And navigation bar is missing. Is it possible to use a side bar and UINavigationBar at the same time?
I see your image I think you have to add another navigation controller before the C****** S****** View Controller or the view controller you want to go
the reason is that there is no UINavigationController before the C****** S****** View Controller and that's why Navigation bar is hidden and you can't move
I'm working on my first iOS app and I'm realizing just right now that I don't have a navigation controller. Since I'm already pretty far in the app and not completely sure of how I would implement a navigation controller, I was wondering if I would need one in order to implement a search controller, meaning a UITableViewController with like a navigation bar on top.
To implement a Navigation Controller you just need to select the View Controller in storyboard then Click up top Editor -> Embed In -> Navigation Controller. You could also just add a navigation bar to the top of the View Controller you are using.
These are the two options for adding a navigation bar, however, neither is required for adding a search bar.
You do not need to add a navigation controller just to display a navigation bar. Navigation bar can be added to any UIViewController.
You can also add just the search controller in a navigation controller, without affecting your other view controllers. This will add a Navigation bar to the search controller and also allow you to navigate to (Push) other view controllers.
I am using tab bar controller and i want to push uiview controller over tab bar controller. but i don't know how we push UIView controller over Tab Bar Controller. Thanks
You need to embed a navigation controller in your tab bar controller screen where you want the push set up to work
If I'm reading your question right, you want to push a view controller over another view controller which is currently displaying tabs.
In this case, I believe you would need a UINavigationController as your root view controller. Inside this navigation controller, you would initially push a UITabController with it's associated view controllers per tab. When it's time to push another view controller over the tab controller, create an instance of the view controller to push and use the following code:
[self.navigationController pushViewController:newViewController animated:YES];
This will push the new view controller over the existing TabController that is currently being displayed.
The question is little vague Hence I will add the two way to push to another view controller we use in common.
From navigation controller : You just need to create an UIButton in the navigation controller and then control + drag the button to another view controller to create a push feature to another screen in storyboard.
From Tab view Controller : Similarly, control key + drag the tab bar item in the tab bar controller to another UIView controller in the story board. Then chose 'show' option to create a push to another UIview controller screen.
Hope this helps.
Tab Bar controller is different and Navigation Bar controller is different.
And as Pittmaster says, your navigation view controller should be root view controller.
I have a hierarchy of 3 TableViewControllers embeded in Navigation Controller and I need to launch on the most detailed level on the top of the hierarchy. If I change 'Is Initial View Controller' in storyboard to the last detailed TableViewController, my app launches with the selected TVC, but with no NavigationBar. How can I launch on the desired level of hierarchy and keep the Navigation Controller managing the stack of views?
Thank you.
You're telling the storyboard that your third view controller is the root view controller--it has no navigation bar. If you want the navigation controller present as the root view controller then you need to make it the initial view controller, then change the navigation's root to your third view controller.
eg:
initial-->[navigation controller]-->[third VC] [first VC]-->[second VC] (keep these around if you want... just disconnect them from the navigation controller)
You would have to select the ViewController that you want as initial and embed it into a NavigationController, and then add all of the other views after that using push segues.
But why do that? Why not just have the first viewcontroller display the data that you will have in the third view controller? you will end up with the same results.
