I segue from one Storyboard where the View Controller is written in Objective C to another Storyboard where the View Controllers is written in Swift 2 and it goes through fine.
However, when I click fire the next segue in the second Storyboard, I get the following error:
*** Terminating app due to uncaught exception 'NSGenericException', reason: 'Could not find a navigation controller for segue 'record'. Push segues can only be used when the source controller is managed by an instance of UINavigationController.'
This is the code that calls the next segue in Swift 2
self.performSegueWithIdentifier("record", sender: nil)
The initial view in the second Storyboard is embedded in a Navigation Controller as well.
Also worth noting, I tried without the first storyboard and my app going directly to the second storyboard, and it finds the segue fine.
Any ideas on what could be causing the problem?
Choose the segue, go to its Attributes inspector and change the Kind from push to Modal. Let the presentation and Transition remain default.
This will work fine for you.
But if you want the segue of kind 'Push' then the first View controller which is written in Objective-C should be embed in Navigation Controller.

I'm getting this follow message when I try open a table item in my 'add' form to update it.
Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: 'Receiver () has no segue with identifier 'verBeneficioSegue''

My code:
When I was debbuging I got error in line 58.
P.S. I'm doing a project exercise for my post-degree in iOS.
I try to clean up project, restart Xcode, restart my Mac, but nothing worked.
From the crash the segue is inside vc named ListarBeneficiosTableViewController
ListarBeneficiosTableViewController: 0x7fbf6d510340>) has
no segue with identifier 'verBeneficioSegue'
and your vc shown in picture is named MyBeneficio ( it's a UITaBarController ) which isn't the same hence the crash
If your purpose is to add another tab to the tabs controller you should drag the segue from the tab to the listoVC and select viewControllers from the popup
Otherwise the segue origin should be ListarBeneficiosTableViewController and it's destination is another vc
You are saying
self.performSegue(withIdentifier: "verBeneficio", sender: beneficio)
in your ListarBeneficiosTableViewController class. This implies that your ListarBeneficiosTableViewController instance is loaded from the storyboard and in the storyboard it has a segue called "verBeneficio".
Okay, so let's look in the storyboard. When we do, we see that the "verBeneficio" segue does not come from the ListarBeneficiosTableViewController. It comes from the tab view controller.
I have a few views embedded in a navigation controller.
I've created a few segues (some from buttons to other view controllers, some from one view controller to another one.
for example I have a segue (Show) from one button to a view controller called name2, when I press the button it works great, but when I try to call it programmatically the app crashes and gives an error.
This is how I call the segue on ViewController1
self.performSegueWithIdentifier("name2", sender: self)
this is from ViewController1 to ViewController2
I also have a segue that is connected not to a button but from vc1 to vc2, gives the same error.
This is the strange error I get:
*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: 'Receiver (ViewController2) has no segue with identifier 'name2''
I tried cleaning the product and also reseting the simulator.
A screen shot of my storyboard
A screen of the identity inspector of viewcontroller1 (it is actually called ViewController in my project)
A screen shot of the segue (name3)
The options of the segue :
Edit:
I found that when I connect a button as an IBAction and then call performSegueWithIdentifier("LogIn", sender: self) from the button it works correctly.
Any help?
Do not connect your Button in Storyboard Editor to the other segue (when you want to call the performWithSegue function within your ViewController1) - just connect the first ViewController to the second One.
Then you can use
self.performSegueWithIdentifier("name2", sender: self)
within your ViewController1 class.
When you set the Segue from one view controller to the other, ensure that you have correctly set the class - see image:
UIStoryBoardSegue was what mine needed.
The error says that you're looking for a segue in ViewController2 but your question states that the segue comes from a button. That would explain why it can't be found.
Try to remove the segue identifier ( name ), build ( cmd + b ), then set the segue identifier and compile. ( in storyboard of course )
Ok the answer is that I'm pretty dumb,
Whenever I was creating new ViewControllers, I was subclassing ViewController which was my first ViewController, instead of UIViewController which made it run recursivly.
I've search almost every related question, but still can not find a clue...
Here is what I did:
1.Create a scrollView using storyboard.
2.Programticaly created 10 myController(which are UITableViewControllers) inside the scrollViewController, So I can use panGesture to switch between tables. and it's working fine.
3.Created a tableViewController using storyboard, set myController to be the corresponding view controller.
4.Embedded the tableViewController in navigation controller.
5.Control drag from tableViewController to a new view controller to create a push segue.
6.Setup segue identifier in storyboard.
The Problem is:
A. When try to segue programmaticaly: use [self performSegueWithIdentifier:#"test" sender:self]; in tableView:didSelectRowAtIndexPath: method.
The exception shows all the time:Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: 'Receiver (<MyTableViewController: 0x8b413c0>) has no segue with identifier 'test''
B. Than I tried prepareForSegue: but it has never been called.
C. I've checked the segue identifier...there is no problem at all.
What's happening here??? Anyone has any idea???
EDIT:
ScrollViewController and TableViewController are separately created on the same storyboard. no connection/segue between them.
PIC Updated.
I have a tabbar ios application. I put (embed) NavigationController in one of the viewcontroller,then added one button and one new viewcontroller to pass. I dragged from button in first vc to new vc and select "push".
But following error message is thrown when I tab the button :
Terminating app due to uncaught exception 'NSGenericException', reason: 'Push segues can only be used when the source controller is managed by an instance of UINavigationController.'
I really don't understand because I have already a navigation controller and also not added any additional code yet.
Thanks for any help.
You may not use push segue with a button that you have created yourself. Try using Modal segue instead.
I just created a calculator app with storyboards using two views. I started my simulator, and everything worked fine at first. On the first screen, I was able to use the "Calculator" button to switch to the second screen, and on the second screen I had a button to go back to the main menu. But when I switched from the main menu back to the calculator a second time, the app crashed, and the following error occurred:
2013-02-21 20:55:36.556 CTS Calculator[22637:c07] * Terminating app

I am not sure why this did not happen the first time I pushed the calculator button. I have a custom segue transition going back to the menu, but not from the menu to the calculator. My navigation controller is set up fine, I believe. Any ideas what the problem might be?
Error shows you dont have a navigation controller. and you are setting segue style to push. Change the segue style to modal and give a try.
Yes. You can use push then the root view controller should be a navigation controller.
