What is the difference between them? I couldn't find any documentation on it. There used to be some which I found in a Google search, but it's now gone: https://developer.apple.com/library/ios/recipes/xcode_help-interface_builder/articles-storyboard/StoryboardSegue.html
Here is a quick summary of the segues and an example for each type.
Show - Pushes the destination view controller onto the navigation stack, sliding overtop from right to left, providing a back button to return - if not embedded in a navigation controller it will be presented modally
Example: Navigating in Settings, for example tapping General > About
Show Detail - For use in a split view controller, replaces the secondary view controller when in a multi-column interface, or if collapsed to one column it will push in the navigation controller
Example: In Messages, tapping a conversation will show the conversation details - replacing the view controller on the right when in a two column layout, or push the conversation when in a single column layout
Present Modally - Presents a view controller overtop the current view controller in various fashions as defined by the modal presentation and transition style - most commonly used to present a view controller in a sheet that animates up from the bottom
Example: Selecting Face ID & Passcode in Settings
Popover Presentation - When run on iPad, the destination appears in a popover, and tapping anywhere outside will dismiss it - popovers are supported on iPhone as well but by default it will present the view controller modally
Example: Tapping the + button in Calendar
Custom - You may implement your own custom segue and have control over its behavior
Embed - You may embed a view controller into another view controller, such as navigation, tab bar, and split view controllers as well as custom containers
Unwind - You may use an unwind segue to navigate back to a previous view controller, even if there’s many screens pushed/presented on top all of them will be dismissed
The deprecated segues are essentially the non-adaptive equivalents of those described above. These segue types were deprecated in iOS 8: Push, Modal, Popover, Replace.
For more info, you may read over the Using Segues documentation which also explains the types of segues and how to use them in a Storyboard. Also check out Session 216 Building Adaptive Apps with UIKit from WWDC 2014. They talked about how you can build adaptive apps using these new Adaptive Segues, and they built a demo project that utilizes these segues.
For clarity, I'd like to illustrate #Joey's answer above with these gifs :

The document has moved here it seems: https://help.apple.com/xcode/mac/8.0/#/dev564169bb1
Can't copy the icons here, but here are the descriptions:
Show: Present the content in the detail or master area depending on the content of the screen.
If the app is displaying a master and detail view, the content is pushed onto the detail area. If the app is only displaying the master or the detail, the content is pushed on top of the current view controller stack.
Show Detail: Present the content in the detail area.
If the app is displaying a master and detail view, the new content replaces the current detail. If the app is only displaying the master or the detail, the content replaces the top of the current view controller stack.
Present Modally: Present the content modally.
Present as Popover: Present the content as a popover anchored to an existing view.
Custom: Create your own behaviors by using a custom segue.
For those who prefer a bit more practical learning, select the segue in dock, open the attribute inspector and switch between different kinds of segues (dropdown "Kind"). This will reveal options specific for each of them: for example you can see that "present modally" allows you to choose a transition type etc.

I am implementing filters in my ecommerce iOS app. I want my filter functionality similar to ebay filter functionality.
Like in the gif attached when user taps on sort filter, the next view (maybe a view controller) opens and shows possible sort options. I am trying to replicate this functionality.
What i tried.
I have implemented a container view controller in which i am showing the filter options. when user taps on any filter item, i am performing a push segue(using storyboard) to next view controller in which i am showing relevant filter options
But the problem.
When i tap on any filter item to proceed further, my app opens the next view controller in full screen, not in the bounds of the container view controller.
See the gif
So how to restrict the next view controller's frame to its parent container view controller?
Also the height of the next view controller should be equal to the number of items in it. See the ebay filters gif. (This is secondary requirement)
Any help would be much appreciated.
I will suggest your view hierarchy should be like as follows.
Embed your container view controller (main filter screen) inside a navigation controller by going into editor (xcode menu) ==> embed in ==> Navigation Controller (story board should be open).
On didSelect method of container view controller, push your inner filter Controller by either storyboard segue or programmatically.
You need to make the view controller that wants to present define a presentation context, and then on the other view controller, make the presentation overCurrentContext. That should make the other view controller present itself only over the context of the parent.
This is the similar presentation style that is used on popovers.
Difference between navigation controller and viewcontroller?
I mean how can we decide when to use navigation controller or a normal view controller?
Just my two cents:
A UIViewController represents a single view and you can put buttons in this view controller to segue to another UIViewController. If you want to segue back to the first UIViewController, you will have to worry about putting a button in the second view controller that leads back to the first. If you are drilling down into view controllers, this can be tedious having to remember to give the user a way back to a previous view controller.
A UINavigationController does a lot of this tedious work for you. As mentioned, it contains a stack of UIViewControllers. It will create a navigation bar at the top that will allow you to easily go back up the hierarchy of view controllers.
In short, if you have a hierarchy of view controllers that you want the user to easily navigate around, inbed your UIViewControllers into a UINavigation controller.
UINavigation Controller is a combination of 2 or more view controllers,those are connected through "segue" feature of "Ios". Benefit of using Navigation Controller is that we can navigate between different screens easily with default "Back" button on each screen . We don't need to give any individual button to move back onto previous screen.
Whereas a ViewController provides a single screen & we can connect more screen using "segue" but we also have to design a "Back" button to navigate onto previous screen.
We should use Navigation Controller , in case where one option resides into another one.Like in an iPhone settings ->Mobile Data Options->Voice->4G or 3G or 2G. It's a hierarchy of menus so here navigation Controller is better option than using UIController.
We should use UiController with "segue " , in case where
we have to choose one option among multiple.Like -
Photos ->There are many folders in which , any one is selected, that are Favourites or People or Places .
Here's a very brief, high-level overview.
Whereas a UIViewController can be thought of as representing a single 'screen', UINavigationController, as the name implies, is used as a means of being able to navigate multiple 'screens'.
From the documentation:
The UINavigationController class implements a specialized view controller that manages the navigation of hierarchical content. This navigation interface makes it possible to present your data efficiently and makes it easier for the user to navigate that content. You generally use this class as-is but in iOS 6 and later you may subclass to customize the class behavior.
Please see the rest of the UINavigationController documentation here: https://developer.apple.com/library/ios/documentation/UIKit/Reference/UINavigationController_Class/index.html
Okay, Thank you everyone for helping me to find out a clear answer on this.
Navigation Controller consists of navigation bar and tool bar to move in and out from view controllers present in navigation stack.Therefore there can be many view controllers in Navigation Controller.
In view controller we don't have this facility and it represents a single screen view.
Please correct me If I am wrong.
See the Navigation Controller discussion in the View Controller Catalog.
Bottom line, a navigation controller actually is a view controller, but it just happens to be one that presents and navigates between other view controllers.
in the google maps app for ios. When you select the settings button, it will show you a view of options such as "traffic", "public transit", etc.
My question is how this is done on ios.
I tried following this tutorial but it says that it won't work on uinavigationviewcrollers. I have seen this partial segue of the the view in apps that use a navigational controller. How do they create that?
It's not a partial segue. It's not a segue at all, it use of containment view controllers.
Instead of a single view controller which transitions to a different view controller image one single master view controller. For simplicity, we'll say this view controller has two views (of the root), both of which cover the the whole screen. For this example let's think of them as "main" view and "menu" view.
Other than these two empty views, the view controller has no content. That's because this view controller does nothing other than manage other view controllers which get stuck into the two views. It will have a couple methods manage them, like presentInMainView:(UIViewController *)viewcontroller and presentInMenuView:(UIViewController *)viewcontroller
When the program starts running the master view controller will programmatically add the map to it's "main" view. The map view controller now cover the whole screen and looks and acts like it's the top level view controller, but it isn't. It's contained. At some point some taps the settings button and the map view controller will make a call to it's parent and say presentInMenuView:... and the master view controller will then load up a second view controller into the menu view. The menu view could even be located off the left side of the screen and the master view controller animates the menu view frame to side it right covering the whole screen. Assuming the menu view controller only has content which covers the left half of the screen you'll see the map view controller hiding behind it.
That really only scratches the surface, lots can be done with container view controllers. You could create a container which lets you brings up a dozen different views all populated with view different view controllers. You could size and arrange them on all over the screen and each child view controller could still only have to deal with it's own contents.
For more info there is the Apple Developer Guide and the WWDC 2011 Videos where it was introduced (session 102)
I used SWRevealViewController For similar type of sidebar animation.They given the good example of how to use SWRevealViewController also please try it once.
I am creating a iPad App and it has several views to load data,but for one view i need to add split view. I dont need split views in other views. They are just detail pages. I search Through the net and found lots of tutorials based on iPad split view. But the problem is they all are creating a project as Split view project or they create a window base app and add slipt view to the delegate. I dont need to do that, I need to implement this split view only for one view. Is There any way to overcome this problem?
You can add the split view inside a Navigation Controller.
Even if the Split View is a container view controller and Apple recommends in the documentation that all containers should not be embedded in other containers, adding a split view inside a navigation controller works correctly and I never noticed any side effect in doing it.
Basically what you should do is:
- in the app delegate create a UINavigationController and use it as root view of your application window
- hide the navigation controller navigation bar if you don't want to see it (showing a split view with a main navbar on top is not nice looking...)
- then add your view controllers inside the navigation bar.
Example: imagine you have this application views sequence:
FIRST VIEW (full view = detail page)
SECOND VIEW (split view)
THIRD VIEW (full = detail page)
So you can represent FIRST and THIRD as standard view controllers (full screen), while SECOND will be a split view. Your app will be initialized by creating the main navigation controller, adding FIRST on it as top controller and using the main navigation controller as window's root view.
Than use the navigation controller push, pop methods to switch between these views or change the navigation controller "viewControllers" array directly if you don't want the recommended push/pop methods.
If you need to add special behavior to the navigation controller based on the type of view on top, just register your app delegate as navigation controller delegate (or a "main controller" object dedicated to this if you don't want to complicate your app delegate).
I am not 100% sure, but it seems to me that you can't use a SplitView just somewhere in your view hierarchy.
The Apple intended way is to use the SplitViewController as the top level controller. The left side of it can include a drill down mechanism with a navigation controller so you are ably to drill down hierarchies and the right side will present details for the item you select on the left side.
If you need a view with some kind of split mechanism in it, you probably have to code it yourself. Or even better: find some other mechanism you can use in your UI.
How are you switching your view hierarchies now? Maybe you could integrate your existing UI into a SplitViewController?
In my app delegate I create a UISplitViewController. I set the delegate to be the detailViewController.
When I run my app in portrait, I have the left top popover button showing that will slide out the split view master.
Then I have a button in my detail view that resets the splitviewcontroller array with a new detail view controller and sets the split view delegate to that controller.
The second detail view displays properly... but I lose my popover button on the second view controller.
Does anyone know how I can get that button to remain on all of my detail view controllers I may add?
Thanks!
See http://www.raywenderlich.com/forums/viewtopic.php?f=2&t=1546 for what I find to be a good approach.
It involves setting the SplitViewController delegate to be the master instead of the detail. The master keeps references to the popoverController and the button, and each time the delegate methods are called (hide and show master) it gets the current detail view and performs the necessary action (add in the button/remove button and popovercontroller).
The master defines a protocol for "SubstituableDetailView" which contains the two methods for showing/hiding the button.
