I can't seem to figure out for xcode 6 how you would connect a button to go to the next view controller. In the view controller scene, I have 2 view controllers, VC1 and VC2. VC1 has a button and I want VC1 to be first, and then have the user click the button, which will lead it to VC2. How do I do that? Basically, how do I link the button in VC1 to VC2?
Just Press control key and drag your UIButton onto another view controller
Ctrl + drag from your button to the next controller in the storyboard. Choose "present modally".
Learn about UINavigationViewController, it's maybe more what you're looking for.

I have to view controller, One has a button and the other is embed in a navigation controller. I Don't know how to make a proper segue to that second view controller including a back (unwind) segue. That is in swift.
You're going to use a navigation controller. Go and select your view in the storyboard, and select Editor -> Embed In -> Navigation Controller. Do the same for the second view. Now, add a button in the first view that connect to the second view on a click. Make sure when you drag and drop that it's a push segue.
Voila! You should now have your navigation controller working.
I just started with Xcode and Swift.
I try to build my first little App for iOS. But now I have the problem, that I don't know how to implement a the back button, so that i come back to the view before.
My Storyboard look like this:
When I open the A-Z view, I want to display the Back Arrow, which turn me back to the Item 2 view.
To open the A - Z view I connect the button "Medikamente A - Z" with the Navigation Controller.
When using storyboards the back button is usually implemented with unwind segue.
I usually like to follow raywenderlich toturials on UI related topics, like this - http://www.raywenderlich.com/113394/storyboards-tutorial-in-ios-9-part-2
It include a detailed example of how to implement back button in storyboards. Quoting from it -
Storyboards provide the ability to ‘go back’ with something called an unwind segue, which you’ll implement next.
There are three main steps:
1. Create an object for the user to select, usually a button.
2. Create an unwind method in the controller that you want to return to.
3. Hook up the method and the object in the storyboard.
When using UINavigationController, whenever you push to a new ViewController the back button will automatically appear, so you can jump back to the previous View Controller.
So it's works like:
UIViewController -> UIViewController -> UIViewController
A back button will appear on the last 2 so you can pop back the the previous ViewController.
You don't have to do any additional coding for the back button to appear, it'll do it on its own. I hope this clears it up. Let me know if you have any questions.
To implement a back button, your root view controller has to be a Navigation Controller.
The first view controller becomes the navigation root of the navigation controller.
If you want to present another view controller, you select a "Show Detail" relationship as the action for the button which should show the view controller. To do this, Ctrl-click and drag from the button to the destination view controller and select "Show Detail".
I had the same problem, even when on the storyboard the back button was visible at design time.
I deleted the segue, and recreated it with "Show" instead of "Show detail". Changing the segue to "Show" had no effect. I think this is a bug, so if you miss that back button delete and recreate the segue.
Suppose I have 3 tabs on tab bar controller:
TabAViewController
TabBViewController
TabCViewController
and in tab C I have one button.
When I click on that button then open the another View (CsubViewController which is not TabAViewController, TabBViewController, TabCViewController). How to call that Another View (CsubViewController) on button click?
And how to come back to the same view after back button click.
It depends. If you are using a NavigationController as the root controller, you push the CSubViewController in your current ViewController by
navigationController.pushViewController(...)
and go back with
navigationController.popViewControllerAnimated(...)
which is the simplest way to achieve your goal.
Or you can write your own code and try to present the CSubViewController modally in traditional presentViewController(...) and dismissViewController way.
I want to pop from childviewContoller to parentviewController in storyboard with out write any code in file with the help segue.
Thank You in Advance.
I would suggest having a button on your child view (potentially in a nav bar or anywhere else on the page). I your storyboard, control drag from the button on the child view, to the parent view. In the pop up, choose your action segue (standard slide in slide out would be the Show segue).
If you choose present modally as your segue, then you can change the Transition on the left to not animate. This give the segue a blunt but removal feel for the child segue.
Hope this helped
This is my first time using story board and I've set up like 5 view controllers with UINavigationController with buttons that push to the next view controller..
So I start on VC1 and push to VC2, then click and button and push to VC3, then click a button and push to VC4, and so on... on the last screen (VC5) I have a "home" button that the user can click to go back to the home screen (VC1), I've set it up so it pushes to VC1, the problem is when the user clicks that they are taken to the homescreen but then there is a back button on the navigation bar and they can go back to the last screen? After they click home they should not be able to return to previous screens without navigating through to them like they had the first time!
How can I accomplish this? Thanks! I'm used to working with xib and programmatically controlling the UINavigationControllers so this StoryBoard stuff is very new to me haha!
It sounds like you want an unwind segue. On the VC1 .m file add the following blank method:
- (IBAction)unwindToVC1:(UIStoryboardSegue*)sender
{
}
Then in your storyboard on VC5 Ctrl-drag from your home button to the green Exit button at the bottom of your view controller. Choose the unwindToMainMenu option and it should now go back to the VC1 when pressed and no longer have the back button as it has popped all the view controllers.
I think the method you're looking for is popToRootViewControllerAnimated:
[self.navigationController popToRootViewControllerAnimated:YES];
