Supporting custom and default unwind segues
ios,cocoa-touch,uistoryboard,uistoryboardsegue
Well, I figured out the issue. Ends up that the super method is alright, the problem lies on a UINavigationController subclass that I made that forwards the call to this view controller. To fix it, I added a protocol that any view controller can implement, and basically asks if it...
Unwinding a segue on interface builder
ios,interface-builder,uistoryboardsegue
A method with with a particular signature, an IBAction with an argument of type UIStoryboardSegue, needs to be in the controller that you are unwinding to. That (and any other methods like it that you might have in other controllers) will show up in the exit button (of the controller...
Receiver has no segue with identifier“***”
ios,objective-c,storyboard,segue,uistoryboardsegue
you call performSegueWithIdentifier:sender: in the viewDidLoad. You can not dismiss a UIViewController that isn't presented yet. viewDidLoad has purely memory management functions, you can use it as (part of a) constructor. What may work, is to start a segue in viewDidAppear, however I would suggest to start with the view...
iOS segue too slow
objective-c,profiler,uistoryboardsegue
The problem, clearly displayed in your log, is that One, Two, Three, and Four are being performed on a background thread. This means, for example, that you are saying: [self performSegueWithIdentifier:@"login_success_new" sender:self]; ...on a background thread. That is so wrong. You must NEVER say anything to or about the interface...

Cannot programmatically perform segue
ios,objective-c,uinavigationcontroller,uistoryboardsegue
Try implementing the shouldPerformSegueWithIdentifier:sender: or prepareForSegue:sender: methods in the 'from' view controller. Put a break point or NSLog() inside the method to inspect the segue identifier. This will prove that you indeed set up the segue correctly in the storyboard. If you want to manually push your next view controller...

Common pattern with segues and table views in iOS
ios,objective-c,uitableview,uistoryboardsegue

IOS - Segue - detect which image was clicked
There are a couple of ways to do this. First of all, UIButtons can actually have a background image, which you could set to your various images. If you're intent on using a UIImageView, you would have to implement its touch event receiving method and handle it yourself. Either way,...

Going back to viewController that was already segued to and is already loaded? No nav controller
You can't do this with a segue, since segues always instantiate new controllers. Instead of a segue, you should create a property for ViewControllerB in ViewControllerA, and instantiate it only the first time you go to it (which you would do using presentViewController:animated:completion). After coming back to A, when you...
iOS: Disable all touches for some time after calling 'prepareForSegue:'

Segues vs. UIViewControllerAnimatedTransitioning
ios,ios8,uistoryboardsegue,uiviewanimationtransition
Some differences: Segues can only be used with storyboards. Animator objects can be used programmatically, or along with segues. Animator objects allow you to set a customized final position and size for your new view controller. Animator objects can be configured to do special animations with navigation controllers and collection...

iOS Swift issue with UIStoryBoardSegue method
