I am new to IOS App development and have a question. I'm trying to segue from one view controller to another. However, it seems that every time I ctrl+drag from the options button to the adjacent view controller and choose the 'show' option, the view controller "shifts" down(bottom picture). Why does that happen and if it is not the correct behavior, how can I do it right? Thanks!
You need to set fullscreen style manually if select model style,
a fullscreen option did not show in Push type, you must use Navigation Controller if you want to set fullscreen for Push

When you click on the segue(the line that connects view controllers) and open the Attribute Inspector in right panel, you will see the Kind is set to Present Modally. This means your view controller will popup on your current screen.
You can change the Kind to Push and it will start showing normally.
Also embed your controller in a navigation Controller
Option 2
If you dont want a navigation controller, you can also change the presentation to full screen.
If you're new to iOS
then I might suggest don't use show and don't use segue from storyboard
If you don't know the concept of navigation controller (push and pop methods), then have a look at it (You may not use show afterwards)
have a look at following link
Swift programmatically navigate to another view controller/scene
I was trying to push an interface after clicking at one button of my two pages consisting rootController and got a weird result.
My requested controller (second image) gets pushed over my first page..but, the second page of my root controller is still there and I can segue into it.
I don't want this.
How can I dismiss all other pages of my several pages controller after pushing a new interface over it?.
Modal is not an option as I want to go deeper after pushing this controller.
WatchKit does not support pushing an interface controller in a page-based navigation layout. As of Xcode beta 4, I understand that you won't see this strange behaviour as the interface simply will not be presented.
I am new to iOS development and have not tried this programmatically yet. I would prefer to get this working in a storyboard.
I'm following this somewhat outdated tutorial from XCode 4.5 in XCode 6.1 to create a series of views connected by one navigation controller.
http://youtu.be/rgd6mCuzlEc
Once I create the second view controller, I am unable to double click the navigation bar to change the name and I am unable to add a bar button to it.
I have a Segue going from bar button "Item" from view 1 to 2. Notice in the "View Controller Scene" there is no navigation item. If I add any elements to the view controller they fall under "View" and not under "View Controller", unlike view controller 1 where it falls under "one".
Is this a limitation on XCode? Am I using the wrong Segue (Show)? Is there a hidden setting or customization I'm missing?
I actually have this working for 2 view controllers and failing the 3rd in a separate project but I don't know what I did to do that so I'm pretty sure it's possible I just cannot reproduce..
EDIT: Workaround Instead of the new adaptive SHOW segue, use the deprecated PUSH segue, add the bar button items, then change back to the adaptive SHOW segue.
Try adding a Navigation Item to the controller and it should work properly
I have two view controllers in my iPhone application (built with swift) built with Xcode 6.1 and uses storyboards.
The first view controller is embedded in a navigation controller in the storyboard and the segue for the second view controller is a 'Show' segue.
When the application is run, it properly shows the transition as a push in iOS 8.x, but in iOS 7.x it appears as a modal without the navigation bar.
My application requirement is to show the transition as a push regardless of whether it's iOS 7 or iOS 8. Any ideas to get this working as push in both versions of the iOS?
I saw a related post where this issue is mentioned, but could not find a solution to the problem: Adaptive segue in storyboard Xcode 6. Is push deprecated?
Any help is appreciated...
Thanks
This solution is different from the others in the following ways:
It includes a method to examine and verify the issue
The cause of the issue is traced to the source (a change in the segue type)
The solution is very simple (delete and recreate a new segue)
Please note the requirements in the text
I just gave a very detailed SO answer that fully explains what is happening and why, but the simple solution is you can delete the Segue that is not pushing and then recreate it on the storyboard. The reason is that there is likely a broken bit of xml in the segue (see extended answer for example/instructions how to confirm this issue).
After you confirm that you have at least one UINavigationController within the view hierarchy, be sure that the segue is NOT a manual segue and does NOT have an action associated with it (by viewing the segue in the storyboard as Source Code). Delete the existing segue and then Ctrl-drag from a UIView/UIControl to the target view controller and if custom action is needed intercept the call to destination controller in prepareForSegue.
Also to confirm that this solution works for you please do the
following:
Verify that your initial view controller (with the arrow on it) is a
UINavigationController and that it has a normal content view
controller as it's root view controller. (or that you embed your
initial view controller inside of a UINavigationController)
Read my extended comments on an earlier response to a very similar question (linked above).
It's possible that you have assigned the Initial View Controller to your UIViewController instead of the UINavigationController. Also, select your UIViewController and check that the "Is Initial View Controller" option is unchecked.
Here is the workaround for that. It looks like a bug in Xcode for iOS 7. You need to create a dummy UINavigationController and link all your free UIViewControllers to this navigation controller. Worked for me.
For me, my storyboard lacked a navigation controller. I am creating the navigation controller programmatically, which works fine in iOS8, but not iOS7.
SOLUTION
In your storyboard, select the main view controller and in the Xcode menu, choose Editor > Embed In > Navigation Controller.
Select the new navigation controller, and in the attributes inspector on the right, under View Controller, make sure Is Initial View Controller is checked.
Run the app. Should be fixed now.
I believe this is a bug in Xcode 7.2. In order to workaround, you can create a "Push (deprecated)" segue and then in the Storyboard editor, select the segue and change it to Show(e.g. Push)
I have had this exact issue with "Show (eg. Push)" for ages and I have just figured it out whilst trying to push a view controller onto a navigation controller that is in a Popover. It seems that the context of the called View Controller is the problem. So this is how I resolved it:
On the View Controller performing the Segue, check the "Defines Context" property in the Storyboard.
In the called View Controller, set the Presentation property to "Current Context".
I ran into this problem and the only solution I found that works for me is to use the deprecated 'Push' segue.
I am using XCode 9 with Swift 4. Note this version came out yesterday (September 20th).
For me this was just a caching bug. I had to choose "Present Modally", run the app and then choose "Show (e.g. Push)". Now everything works fine.
Basically the answer of Jomafer is partly correct. The controller which you are pushing needs to be preceded by a UINavigationController. You dont really need to push the UINavigationController at all. As long the storyboard knows its within a UINavigationController, all is well.
When a "Show" segue comes up as a modal segue in testing it is usually one of two problems:
The first view controller is not inside a navigation controller.
The storyboard XML is corrupted.
The solution to #2 is usually to remove and replace the segue, and it should correct itself. Sometimes just switching to some other presentation style, running, and switching back to "Show" fixes it.
This can also happen to "Show Detail" segues, and it can be more insidious.
Example:
I have a series of view controllers arranged in a UISplitViewController. They have segues Show->Show->Show->Show Detail. The last segue kept coming up modal. I tried everything to fix that last segue. The problem was that the upstream Show segue had been corrupted into a Show Detail segue (even though the storyboard still said it was a Show segue). I had been testing on iPhone, and I did not discover the real problem until I ran it on the iPad simulator. The segues were now Show->Show->Show Detail->Show Detail. On the iPhone the third segue looked just like a Show because it collapsed onto the navigation controller. However, it is still the detail view controller, and you cannot have a Show Detail from a detail view controller, so the OS does what it can to get your view controller on screen and displays it modally.
Lesson 1: Always test your UISplitViewController on iPad to make sure the segues are doing what you think.
Lesson 2: If your segue is coming up modal unexpectedly, check the upstream segues for corruption as well as the segue in question.
Problem in my case was that I created Show (e.g. Push) segue before putting ViewController as rootViewController of UINavigationController. In other words I didn't have UINavigationController.
Then I deleted seque, added UINavigationController and added seque again and it worked. Tested on Xcode 9.0.1 / iOS 11.0.3.
I have built some view controllers in storyboard like in the picture below
I already implemented the data inside them, modal segue is used for transitions in between. Now I just realise when I push "back" button, previous view won't be properly loaded. I figure I should switch to navigation controller and add those controllers in stack instead. But I don't know how to go from where I am now.
I think I should make changes programmatically because I found building navigation controller in storyboard won't have much variation in UI design (at least I don't know how to implement existing pages in that way). So what should I do to implement programmatically? Please help me, thanks!
Select Category View Controller and go to menu: Editor > Embed In > Navigation Controller. Then change segues style from Modal to Push.
