Can we use the sequences of 3 launch images in iphone/ipad?
No. A launch image is just one image (for that particular device/scale/orientation).
We show an animation in one of our apps, which starts immediately after launch (on the root view controller).
Technically not. But you can show additional images yourself after the app finished loading. The Default.png is used to display something (instead of a black screen) while your app loads.
Once it finished loading, it is immediately replaced with your main window's content. Then you can add UIImageViews or UIViewControllers to display anything you would like. But at this point your app is done loading and it would be a waste of time to show anything else, than your app's live content.
You cannot use sequence of images in default launch.
But you can do with the customise the code on view to change the images sequentially with a timing difference once the default image is loaded.
No. you can use only one image of different type of device like normal size,3.5 inch and 4 inch
You can add a new viewcontroller which will display the different type of splash screen image in the application didFinishLoading.
This way you display the more splash screen display a bit longer.

I want to use Activity View Indicator on my app while it's loading, so I have LaunchScreen.storyboard.
I use "Behaviour - Animating" on my AVI, but it is not animating.
When I use Act.V.Indic. not in LaunchScreen - it is animating.
The LaunchScreen storyboard is static. iOS actually creates an image from the LaunchScreen and displays that image. It is impossible to have any dynamic or animated content in a LaunchScreen storyboard.
If your app takes time to load, then your app should display another screen as soon as it starts and that screen should show the activity indicator view.
Launch screens are static. Even though you set it to animating, it won't animate, simply because it can't. Think of them as outlines for your launch images. iOS will generate an image from them, that'll be shown to the user. They are a more convenient way of generating launch screens but aren't interactive or dynamic.
So I am new to iOS development and I have a question about the launch screen.
My app will have an image (that loads when the app opens from the internet) this can change anytime the image is updated on the website, so what is the done thing when designing a launch screen as the image could be different to what is on the launch screen?
Thanks
In Apple's Human Interface Guidelines, they suggest that the launch screen should match the first screen of your app. In the example they give, the only parts of the launch screen are the non-dynamic parts (the UI around the web content).
Design a launch screen that’s nearly identical to the first screen of your app. If you include elements that look different when the app finishes launching, people can experience an unpleasant flash between the launch screen and the first screen of the app.
The launch screen is presented before your app loads, and it should be used for static content only.
If there are any UI elements around the image that is displayed, show those in your launch screen. If not, choose a neutral background color that works well with the theme of your app.
Omit the image. A launch image should be a bare outline of what the screen will certainly contain. It might be no more than the correctly-colored background. It is just to cover the gap between nothing and something.
Read the Guidelines: https://developer.apple.com/ios/human-interface-guidelines/graphics/launch-screen/ Look at the picture on the left. That's a launch screen — basically empty.
LaunchScreen image is always the same..
You can set it in LaunchScreen.storyboard
The launch screen is used to display something whilst your app is initialising, making network requests or whatever.
You shouldn't be looking to load dynamic content here as if a user is on a very slow connection then they wont see anything until your image has loaded. This is why it doesn't have a view controller associated with it. it should be static.
You should only really be loading your logo or something in here, you could just use the company name. it will only show for a short amount of time. then when assets change, submit the changes to store
I have some issues with the launch screen images, when the app is started. I currently using the default image set that contains the #1,2,3x images, but I figured out that there is also an Launch Image Set. This will solve also the problem of different iPhone sizes with the export for multiple screen resolutions. But after uploaded the correct images to the launch image set, I can't select them within an UIImageView in the launch storyboard. Is this even possible and if so, how can I use that in storyboards? Or is there another way to do this?
I cycle through an x amount of images that will randomly display when opening the application. So every time you open the app, it will display another image.
You can't use launch images in the rest of your storyboards. You should create a normal image set to use in the rest of your app and use constraints to get it to adjust size to whatever device the app runs on.
The launch image is shown while your app is loading ("launched", loaded to memory). So you can not run any code at this time.
As the launch time is not that long, a common approach is to initially show a view, that looks 100% identical to the actual launch screen for 3 seconds or so. So you can do run code, animations or such there.
In my personal user experience this is an ugly approach, as you let the user wait for no reason but to show of you CI.
To sum it up: You can not have a random initial launch screen.

Some time ago we decided to put our application-loading logic into a separate function that is called after DidFinishLaunching. We are doing by showing a new UIViewController that contains the default splash image (as described here). The two reasons for this are:
We can automatically show the current version number on the splash screen.
If the loading time takes more than around 10 - 15 seconds, the app would be killed by the OS. We had this situation one time during a version update until now where a large DB / file reorganisation took up to 15 seconds. If the app would have been killed by the OS, the data would have been left in a corrupted state.
This worked fine. Now since iOS 8 things have changed a little bit and we are supposed to be using a launch screen xib or story board. I tried to load the xib in a UIViewController (our own splash screen), but this resulted in an NSInternalInconsistencyException - loaded the "" nib but the view outlet was not set. As I found out, launch screens must be pure static, same as the original launch images.
I like the concept of having only one launch screen instead of a dozen launch images. How would I be doing this? Is there a way to programmatically load the original launch screen xib and show it in my own splash screen view controller? Of course I would then also like to programmatically add the version number as I did it until now.
Edit: Putting the application to sleep in DidFinishLaunching() is not an option, see second point above.
You can't hold launch screen for longer period.
You can add a ViewController with default.png in the applicationdidFinishLoading. Show this controller for few seconds(5 secs) and replace with next view controller.
Note: According to the appstore guidelines state, you should not
delay starting of you are any longer than necessary.
I am currently trying to figure out how to change the splash screen (default png) in iOS.
From what I understand, the ideal way to present an application to the user at the very beginning is to have the launch image a skeletal representation of the UI elements in the app (like this: http://h.dropcanvas.com/u90tr/IMG_0388.png).
Now, in my application, when I switch tabs and go to another app or the home screen, when I return to the application, the splash image is no longer relevant to that particular tab.
Ideally, what I would like to do is programmatically change the launch image in applicationDidEnterBackground so I can present a relevant splash screen when returning to the application.
Many thanks for your help!
You can't do this, and shouldn't need to bother. The launch image (it is NOT a splash screen!) is only used when your application is launched from scratch. If its just been into the background, the OS will take its own snapshot and use that when you return to the app.
Your launch image therefore only needs to show a basic representation of your app as it will appear when launched from scratch. If you have a tab bar, it shouldn't show any icons or labels (as they can change with localisation) - literally just the black glossy background, all the way across. In your link, I would lose the bar button item, for example.
If you can't make a representative image, a plain black image (or no image at all) would be best.
