I am new to iOS app developing.
I want an unwind segue without any animation, but I don't know how to get that. Could anybody help me out???
Thanks a lot!!
If you just need to remove the last viewController displayed from your navigation stack you can use [self.navigationController popViewControllerAnimated: NO];
I think, you should perform custom animation for unwind segue.
and don't animate your VC in that animation.
Try this to perform Unwind segue with animation: http://spin.atomicobject.com/2015/03/03/ios-unwind-segue-custom-animation/
I'm searching for an answer to this as well. The one thing I do know, which hasn't been mentioned yet, is that in Xcode 7 there's a new box you can uncheck.
Go to the storyboard and select the unwind segue. In the inspector you where the ID and class are, below the text fields there's now a checkbox which says "Animates". You can uncheck it, telling it not to animate the unwind.
Too easy, right? Yup. The catch is that it's new and only works for iOS9. If you're targeting anything earlier, you need a different solution.

I can't find an answer to this seemingly basic question. Let's say I have a storyboard with two view controllers A and B and a segue transition from one to another. Now, I created a different view controller C and now would like to redirect the existing segue from A to C.
I Ctrl dragged it, command dragged it, etc. it does not seem to work. In the real app, I have way too many segues to try to re-create them from scratch. Is there an easier way?
This question is not a duplicate as flagged since I'm trying to reuse existing segue, not direct to a different controller.
Thanks!
Option 1,using XML file
First,right click the Storyboard file.Then select open as Source
Code
Search segue,then change the destination id
<segue destination="Esd-4c-JQq" kind="show" id="Jnu-RW-1O5"/>
Option 2,using Interface Builder
First, selected the segue source ViewController
Second,Create a same segue(Control+drag),like picture shows
Now,you have two same segue,
You just need to delete the old one
You can drag segue from ViewController icon at the top of ViewController to other Controllers.
Just give identifier to segue by clicking segue pointer on storyboard and then opening attribute inspector and finally you have to do just that code.
Case 1: Push Segue to B from A
[self performSegueWithIdentifier:#"PushB" sender:self]; //PushB is segue identifier
Case 2: Push Segue to C from A
[self performSegueWithIdentifier:#"PushC" sender:self];
Note : You must have Navigation Controller as initial point of storyboard before performing performSegueWithIdentifier.
Hope this will help.
Delete the previous one from A to B and then recreate new one from A to C.
Hope it helps.
I know this was a problem in the Xcode betas and I read that this was fixed in the Xcode 6 GM, but I am having trouble with it now. I have create an unwind segue but it doesn't unwind properly. I have both views set to their respective custom View Controller, I have the unwind function in the view controller I want to unwind to, and this is the code I'm using:
#IBAction func unwindToObjectives(segue: UIStoryboardSegue) {
}
Can someone please help explain what I'm doing wrong? I know there is a work around, but I am trying to avoid using it. Also, I apologize for asking this menial question, I'm extremely new to Swift and iOS development.
I fixed the problem. In the end I just remade the custom TVC (with the segue), deleted the VC, and change the segue to a modal on and it work. I don't know how that helped, but it did.
I am in a situation exactly like this post, but for whatever reason, only one of my performSegueWithIdentifier:sender works.
I have a View Controller (embedded in a UINavigationController) with two buttons, Cancel and Done. When clicked I want Cancel to unwind to one screen, and Done to unwind to another screen; however, this only works with one of the two segues I have set up.
- (IBAction)clickedDone:(id)sender {
[self performSegueWithIdentifier:#"unwindToHome" sender:self];
}
- (IBAction)clickedCancel:(id)sender {
[self performSegueWithIdentifier:#"unwindToViewEntries" sender:self];
}
"unwindToHome" works fine while "unwindToViewEntries" does nothing. No error, no printing, nothing. If I switch the segues and buttons, "unwindToHome" will still work while "unwindToViewEntries" does nothing.
I have unwind methods in both ViewControllers I want to unwind to and there are no other actions attached to the buttons.
I find it really odd that only one works. I've looked them over several times and there is nothing different that I can see.
Thanks in advance for the help. If there are some more things I should check please let me know!
I've already looked at solutions for the following posts:
How to unwind programmatically to 2 different VC
performSegueWithIdentifier not working
I've also tried removing the segues and re-adding them, as well as deleting and re-adding the entire view controller. Every time, the same behavior.
EDIT: I should also mention that I've tried adding other segues in different views and none of the new ones I add work. Only "unwindToHome" seems to work, and I can't figure out why.
In the storyboard make sure that both segues show that it is a show (push) segues. There was a question earlier,which is a little bit different, that if you create two segues from the same button Xcode was setting one push the other modal.
Happy coding!

I'm working on a storyboard-based iPhone app.
I am successfully using unwind segues to navigate my stack of view controllers.
However, when I present a modal view controller I cannot seem to be able to trigger the unwind segue that I have specified in the storyboard file.
Is this normal or a bug?
Problem solved.
Apparently I've hit some glitch with the storyboard editor.
What I did was to delete the destination (modal) view controller and then re-create it.
Works fine, now.
Bug report filed.
So I have the same problem (more than two years later!). I haven't fixed the underlying issue, but I found that a modal view being presented with a default presentation style will unwind OK, but one that uses a page sheet presentation style simply doesn't work. The unwindToViewX method gets called on the parent view controller that the unwind segue is moving to, though, so I've circumvented the issue with the following code:
if (self.presentedViewController) {
[self dismissViewControllerAnimated:YES completion:NULL];
}
This saves me from setting up a delegate system as the unwind action is doing all the heavy lifting, but also avoids an issue where perhaps the unwind action might work one day, because in that case self.presentedViewController should return NO because the unwind action worked correctly and we won't end up dismissing two view controllers by accident.
I hope this helps others in the same boat, but I'd also like to hear if anyone else has better solutions.
Is it possible to not use a NavigationController and change views with an animation/segue with a storbyboard. I cant seem to figure out how to accomplish this. I thought it would have been pretty simple but no luck. I just have two views and want to transition without adding a navigationcontroller.
Sure, just create the segue and select "modal" in the menu that pops up instead of "push".
When you want to return you do it programmatically with:
[self dismissModalViewControllerAnimated:YES];
T.J. is right about selecting a modal segue, but -dismissModalViewControllerAnimated: is deprecated in iOS 5+.
You should use -dismissViewControllerAnimated:completion: instead.
With the advent of iOS 6, you may also be able to use 'unwind actions' for dismissing presented controllers with unwind segues.
