uistoryboardsegue

In my iOS 7 app, I detected if a segue was a popover via this check in prepareForSegue : if ([segue isKindOfClass:[UIStoryboardPopoverSegue class]]) But now that I am using adaptive segues, the Present as Popover segue is no longer returning true in the above check. This is because segue is no longer a UIStoryboardPopoverSegue , instead it is a UIStoryboardPopoverPresentationSegue . However, one cannot simply add the Presentation word because that's not defined. What is the appropriate way to detect when the segue is a popover from an adaptive segue , as opposed to a full screen modal

I have a simple UINavigationController which pushes a UIViewController onto the stack via a custom segue. I then implemented an IBAction on the first UIViewController to perform an unwind action and I implement segueForUnwindingToViewController. Unfortunately, the segueForUnwindingToViewController is not being called (I did confirm that canPerformUnwindSegue is being called on the first VC). I have not seen any simple examples of this behavior. Can anyone please help? Thanks. Here's the code from the root view controller of the NavigationController. - (IBAction) unwindFromSegue:

In my simple app, I have created some controllers with basic segues between them: Yellow controller -> BlueController -> GreenController -> OrangeController . Every of them has its own custom class. From OrangeController I created unwindSegue to my YellowController . It is ok. Within every class I put: override func unwindForSegue(unwindSegue: UIStoryboardSegue, towardsViewController subsequentVC: UIViewController) { print(unwindSegue) print(subsequentVC) } But it was not called at all. Why? What demo should I prepare to test this functionality? The same is with: func

I want to pass my data from one ViewController to another VC on VC dismiss. Is it possible? I've tried the next method and no success: On button click: self.dismiss(animated: true) { let storyboard = UIStoryboard(name: "Main", bundle: nil) let controller = storyboard.instantiateViewController(withIdentifier: "EditViewController") as! EditViewController controller.segueArray = [values] } when EditViewController appears again, my segueArray is nil there. How can I pass my data from my ViewController to the EditViewController on dismiss? the_legend_27 The best way to pass data back to the

I'm building a large storyboard and I was wondering if anyone has come up with helpful naming conventions for segue identifiers . It looks like Apple just uses 'ShowX' in their examples where X is the name of the view it is showing. So far I prefer to use 'PushX' or 'ModalX' to keep track of which type of transition it is. Anyone have any other tricks or tips? There is no correct answer for this question. It depends on taste. I mitigate for readability. Don't be shy to give a long name for your segue identifier; give long and expressive names because Objective-C is a very verbose language
