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

When I drag to the next view controller to add a segue the new view controller has no navigation bar with a back button. I thought that was the default when you add a segue to a new VC. I'm also not able to drag a navigation bar to the top of the table view controller. Am I doing something wrong? Thanks.
Maybe the problem is the kind of segue that you are you using. The Segue type should be "Show (e.g Push)". Click on the segue and in the right panel go to the "attributes inspector" (the 4th one). And here you can check the type.
A view controller like in your case only shows a navigation bar by default, when the view controller itself or one of its parents (connected by a push-segue) is embedded in a navigation controller. Obviously, the navigation controller must not have hidden the navigation bar.
So, you either forgot to put a navigation controller into play or your segue is modal and not push.
Well, it's two years since you asked your question, but when it happened to me, I realized it was because at one point, I had accidentally created my segue as a different kind of segue (a detail one, I think), but changing it back to a "Show" segue didn't actually change it's behavior. When I found the segue in my storyboard xml, it was listed as a "Show" segue, but with a different custom action that suggested it was going to do something completely different.
Anyhoo, deleting and recreating the segue in Xcode fixed it. I probably could have also deleted that custom action in the xml file, too.
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 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.
I'm mainly from a C# background, so the workflow for iOS is a bit unusual for me, at least for now.
I was having a problem having simple segue from a main menu, to a another menu/work area, and then with the ability to go back to the main menu.
For a test, apparently I did something wrong.
I didn't write any code for this test to exhibit the problem.
What I did was just,
create a new single-view app
drag an additional view controller onto the work area
drag the start arrow to the new view controller (so it becomes the initial view, same thing as checking the checkbox to set it as the initial view)
added a button to each view controller
Ctrl + clicked and dragged the buttons to the opposing view
for the segue type, I chose "replace"
now the program crashes if I hit the second button to go back to the "main menu" (green view controller in this example)
So what am I doing wrong? Do I need to add some form of delegate or something?
I did find this, though it present fewer segue options in the tutorial than what I have.
https://developer.apple.com/library/ios/referencelibrary/GettingStarted/RoadMapiOS/SecondTutorial.html
These are the options I have when I Ctrl + Click from a button to another view
-Push
-Modal
-PopOver
-Custom
-Replace
"Have you embedded a navigation controller? You need to go to editor->embed in-> Navigation Controller. You need a navigation controller for push segue. – Kaushal Bisht"
This solved it for me. Now I'm just going to work on replacing the navigation bar with custom UI controls.
Thanks everyone! :)
I have an application which has 5 tabs. I also have another view which you can access from tab3 via a selection of buttons. I will call it view 3b. View 3b populates with information based on which button the user selected in view 3. After the user puts in all the information required the app automatically takes them back to view 3. I want to add the tab bar to this view(3b) but I do not want it to have its own tab. I just want to use it so the user can navigate out of this view back to the rest of the app if they want to exit the screen early. Does anyone know how I can attach the tab bar to this screen without having a tab added for this screen. I am using Xcode 4.6.2 and am using storyboards to set up my app.
Any help would be appreciated. I've done a bit of searching but everything I find just explains how to use tabs.
Any help would be appreciated. Thanks.
It sounds like you need to use a UINavigationController.
When you set up your UITabBarController, instead of linking the third tab directly to your 3rd view controller, connect it to a UINavigationController, and then set the root view of that UINavigationController as the UIViewController you want as your third tab.
From there, you can set up your buttons to perform a push segue to your second view controller (view 3b from your question). If you do this, not only will you keep the tab bar on view 3b, but a back button will automatically be placed in the top left of the page so the user can simply go back to view 3. If you don't want the navigation bar that appears to be there, you can instead uncheck the "shows navigation bar" checkbox in the UINavigationController's attributes inspector.
I hope this helps!
