I'm fairly new to iOS development. I'm working on an App that segues to multiple table view controllers. When my application launches, it loads view controller A. I then click on a row in View Controller A to segue to view controller B. The navigation button (back button) in View Controller B shows the title of View Controller A. I then click on a row in View Controller B which will segue to View Controller C. When I click a row in View Controller C, I segue back to View Controller B. My problem is that when I segue from View Controller C to View Controller B, the navigation button (back button) on View Controller B shows the title of View Controller C. I would like it to still show the title of View Controller A. Can anyone help on how this can be done? Sample code will be great. Thanks.
If you are going to use a segue to go from C to B, then you need to use an unwind segue. This has the advantage over using popViewControllerAnimated: in that you can use prepareForSegue to send information back to view controller B just like you would for a forward segue.
You can try to use the popViewControllerAnimated function. Have a look here : http://developer.apple.com/library/ios/documentation/uikit/reference/UINavigationController_Class/Reference/Reference.html#//apple_ref/occ/instm/UINavigationController/popViewControllerAnimated:
I think its pretty simple to use so I hope you will not need sample code.

I'm making an application that has:
Navigation Controller -> View Controller -> Navigation Controller -> View Controller -> Navigation Controller -> View Controller.
This is making it so that there's no back button on the second view controller, only the third one, and I can't get it to appear. I'm fairly new to iOS and simply want to have a path of view controllers that the user can navigate down and back. Is there a way to add the back button to the second view controller's nav bar? Is there a better way to do this? Is it problematic to just create buttons at the top of views that perform segues?
I found some Objective-C solutions but couldn't find anything in Swift. Thanks for your help!
Remove all the navigation controllers except the first one.Your app must be like this..
Navigation Controller -> View Controller -> View Controller -> View
Controller.
Call segue to move to the other controller .. Just dismiss your controller if you have modally showed them on back button pressed or pop them from
navigationController
if you have pushed them.
Now for Back, you can do it in multiple ways. One of them is, add a view on the top of your controller, add a button on it and implement an action when someone taped it..
I hope you will got that ...
I have a View Controller (A) with a text field and some other things in it.
When the user presses a button on View Controller A it segues to View Controller B using "Present Modally".
How could I preserve the state of View Controller A (e.g. text in the textfield) when returning to it from View Controller B. I would rather avoid using NSUserDefaults if possible.
Thanks!
When you present view controller B modally on top of view view controller A, view controller A is not closed - it's just covered by view controller B. The close action on view controller B should invoke dismiss(animated:completion:) to dismiss the modal. When you do that you can be certain that view controller A will be revealed with its state intact.
You should NOT use a segue to go back to view controller A. That would create a new copy of view controller A that would wind up being displayed on top of the original view controller A and the new view controller B. That is a bad idea.
I have searched around and all cases of using the pop to return to a previous view controller seem to be based around using a navigation controller, I am using a tab bar controller and have no real need to the navigation controller and so havent implemented it.
I load this detailed view controller via a segue based on rowindex selected in a list controller and just need to close it when they are done reading with a close button.
Is there still a method that can be used to pop a view controller without it all being housed in a navigation controllers unnecessarily?
Why don't you use a Storyboard and use an Unwind Segue to go back to the prev. View? Take a look at this Unwind Segue, hope will help you.
I want to design a routing mechanism for management view controller transitions in objective-c.
Two view controllers, without reference to the other side of the pointer, the transition is completely controlled by the route.
How to achieve the route?
Thanks for your help.
I hope you think like this.
Route = Segue (In Xcode)
Take Two View controller
Make 1st Embed in Navigation controller (Which is must be initial View Controller)
Put One Button in 1st VC
Press Ctrl + Drag Mouse from button to 2nd VC (One popup will be show, then select Push)
Run Project
Press Button
Lol
You can use Storyboard's segues. Create view controllers and segues between them. You can use Push Segue or Model Segue. Push Segue will let you pop next view controller too, and you will have to embed your first view controller into navigation controller. For Model Segue, you can move from one view controller to another but to return to previous view controller, you will have to create another segue.
I think I find the approach to answer this question。 Here is the similar project.
Hi I have a view controller A that deal with view A, and a view controller B for view B. Now to go to view B when user click a button in view A?
You can create a UINavigationController , the NavigationController's rootViewController is view A . When the user clicks the button at view A, push View controller B onto the NavigationController. use this method: pushViewController:
good luck with you!
Push View Controller A onto a UINavigationController to begin with. When the user clicks on the button in view A, push View Controller B onto the navigation controller.
Create an IBAction method for the button, initialize your view B, and push it onto the view stack.
This is very well documented in the documentation. You should check it out!
If you are using Storyboard this becomes much much easier. Just select the scene for View A in the Storyboard view, then on the Menu bar, Click Editor->Embed In->Navigation Controller. This will add the Nav Controller automagically and make View A the Root View Controller. Then it is just a matter of wiring up a Segue from View A to View B.
