I'm using Xcode 10.1 and my app is a universal app. I'm having a design issue when loading the launch images using the assets i.e. it showing some black screen background in iPad Pro 11 inch and iPad pro 12.9 (3rd generation) devices other than that it working fine in all devices. So how can solve that issue? And If I want to use the LaunchScreen.storyboard file how can I set a single image to satisfy all screen sizes(which image size and what resolution(2x or 3x) have to use) ? or how to use the Static Launch Screen Images by the apple click here?
Any help appreciated.
As you wrote there are two ways to configure the LaunchScreen:
Static image from the special imagest - LaunchImage.launchimage
Designed screen that can hold multiple UI elements - LaunchScreen.storyboard
If your launch screen is simple enough and you choose to use Static image please make sure that your Info.plist doesn't hold the following key: <key>UILaunchStoryboardName</key> <string>LaunchScreen</string>, if it does then the static image won't be used.
The LaunchImage.launchimage holds an image for all device types and tells you which image size to use.
If you use it and do populate all the images and still some devices has no launch image try cleaning and rebuilding your app and uninstalling and reinstalling the app from your test device or simulator. Also consider updating your environment (xCode).
If you choose to use Designed screen please avoid setting the source of your ImageView to the LaunchImage.launchimage, its a special imageset. You can only use regular x.imagesets with less images (1x 2x R4 3x).
Take a look at the following answer to a different question, it explains the mechanism that auto selects the image, it also has table that connects iPhone type to the selected image.
I am developing an iPhone app for iOS 6.1 and 7 (using Xcode 5). I have a problem with iPad launch images.
On iPad 7.0 and 7.0.2, the launch image is not showing up(in 6.1 works!): I get black screen while app is loading.
I don't face this issue with iPhone 6.1 and 7.0.2, although I set all launch images required for iPad and iPad retina (landscape and portrait) and I use Asset Catalog.
What am I missing?
Recently I faced same issue with my App designed only for iPhone , I had the problem where the launch images would not appear in iPad (On iPad ios >= 7.0.x the launch image is not showing up I get black screen while app is loading (in iPad ios < 7.0.x it works fine )).
I don't face this issue of launch image with iPhone worked fine in all iOS versions.
Solution: Is to update to asset catalog to manage your app's images and target only iOS 6 and Prior.
Steps :
Step 1:
Step 2:
Step 3: on the top right corner click on the 'Attribute Inspector' icon. Here you can set the Target OS for the Launch Images.
Uncheck the iOS 7 check boxes for iPhone, Now you should be able to see the launch images for iPad on iOS >= 7.0.x.
If you have the same situation like mine, that's solution:
My app is landscape only, iOs7 only, ipad\iphone (XCode 5).
Problem: black launch on iphone (and simulator), normal launch in ipad.
Solution: go to Images.xcassets - Launch Images - select it. Uncheck at right all "iOs7 and later" boxes. Check "iOs6 and prior" boxes and fill empty spaces with images.
Strange, but works.
Per Apple's documentation (link); an empty iPad specific storyboard may be the answer. I've also seen issues where the initial view controller is not set within a storyboard causes a black screen. A variant of this issue might be an incorrect setting in the app plist.
Technical Q&A QA1780
Why does my app launch to a black screen on iPad?
Q: Why does my app launch to a black screen on iPad?
A: Apps that have been designed only for iPhone may launch to a blank screen when run on an iPad. This is caused by the presence of an empty iPad specific storyboard in the app bundle as well as an iPad specific UIMainStoryboardFile key in the app's Information Property List (Info.plist) file. Both are automatically created by the various Xcode template projects if the Universal option is selected.
...
In Xcode
Look for a file named MainStoryboard_iPad.storyboard in the file navigator. If this file is present, remove it from your project.
In your app's Information Property List
Look for a key named Main storyboard file base name (iPad) or UIMainStoryboardFile~ipad. If this key is present, remove it. You should also remove any other key suffixed with (iPad) or ~ipad.
Finally, test your app on an iPad or in the iPad simulator and verify that it behaves as expected.
I requested Apple support and it turned out that it's a bug. They asked me to report it and I did. Here is the report id : 15340531.
Now it's up to them.
Using LaunchScreen.storyboard
I was having a similar problem until I found the following settings in the General Project Settings.
Set your Main Interface to your main storyboard file. Mine is called Main.storyboard.
Set your Launch Screen File to your launch screen storyboard file. Mine is called LaunchScreen.storyboard. (This is what I had originally ommited.)
After that the launch screen loaded first and then the main story board loaded shortly later.
Try set the image again make sure that resolution of the splash screen is according to the iOS 7 guidelines
I know this sounds stupid. I've had bugs like that when I saved a file in psd-format with a jpg extension. Just 1 wrong click while saving your launch image.
After having tried several solutions found here, I suspected that the iPhone was trying to launch in Landscape orientation, and thus not finding any corresponding launch image. Indeed, the simulator was starting in Landscape for a reason I was not understanding.
Finally, after reading Apple documentation, I found that it's probably the order of keys in "Supported interface orientations" of the info.plist file that was not adequate. The Portrait was the last item. When it's the first item, the app launch in Portrait mode and find the image.
Remove previously installed app from the device or simulator, Then relaunch the app after clean.
I had the problem where the launch images would no appear in iPhone (3.5 or 4 inch) in iOS 7, but the iPad had no problems with iOS 7.
Long story short is I disabled the asset catalog for the launch images only. So I'm adding the launch images the old fashioned way. That seems to have solved the problem.
I will have to do more testing tomorrow, but it seems the problem is solved (at least in my case).
in Xcode 5 , make sure thay you add all needed images mentioned in your app target.
I am assuming that when you are using Asset Catalog, you have ensured that you have the Images.xcassets target membership added correctly. I am mentioning this since if you have multiple targets, looks like you have to add them manually (and you have not provided any screenshots so one can be sure).
Now that you have not really provided a screenshot of the "LaunchImage" overview of Images.xcassets folder in your project, I can only guess the probable reason. Looking at the fact that the launch images work fine for iPhone (6.1 & 7.0.2 and iPad (6.1) and do not work only for iPad (7.0 and upwards), I think you could perhaps look at as to whether the dimension of the images for iPad Portrait and iPad Landscape are proper for iOS7. Specifically, you should see your launch images and not empty rectangles as seen in the attached pic-
This can happen due to the fact that you still have the iPad launch images for iOS7 created excluding the status bar area. Prior to iOS7, the iPad launch images were created to exclude the status bar area, but it's a must on iOS7 that all the launch images must include the status bar area. Please go through the section "Things Every App Must Do" in Apple iOS7 UI transition Guide (https://developer.apple.com/library/ios/documentation/userexperience/conceptual/TransitionGuide/TransitionGuide.pdf).
The following screenshot should explain what I am talking about-
e.g. you can see that iPad Landscape Retina image dimension for iOS6.1 and previous is 2048x1496 (excluding 40 px for status bar) but the dimension for the same image for iOS7.0 and upwards is expected to be 2048x1536 (including the 40px for status bar). So, if you have not changed your images accordingly, you will see black screen for images on iPad 7.0 and upwards. On iPhones, you will not face this issue since iPhone launch images always cover the status bar, be it iOS6.0 and iOS7.0- so the new UI requirement is already met for iPhone launch images.
I found this answer which worked for our app (iPhone only, but used on iPad): https://stackoverflow.com/a/19448782/1258419
To summarize from that answer:
How to do it. Go to the asset catalog. And on the top right corner click on the 'Attribute Inspector' icon. Here you can set the Target OS for the Launch Images. Uncheck the iOS 7 check boxes for iPhone. Now you should be able to see the launch images for these devices.
I encountered a similar problem in landscape, my iOS 7 launch image wasn’t displayed while the iOS 6 did. Mine was the iPhone Retina 3.5” launch image.
Since I have another app in portrait that didn’t share this issue, I did 2 things:
In info.plist, under “Supported interface orientations”, I added the
2 portrait modes as well, and put them before the landscape, like
this:
Item 0: Portrait (top home button)
Item 1: Portrait (bottom home button)
Item 2: Landscape (right home button)
Item 3: Landscape (left home button)
Implemented this method in the View Controller:
-(NSUInteger)supportedInterfaceOrientations{
return UIInterfaceOrientationMaskLandscape;
}
This works with or without the Asset Catalog.
This is an update for iOS 8.
I got the same problem when I tried to add a LaunchImage to my iOS 8 app.
Apple enables developers to use a xib, whose default name is LaunchScreen.xib, to render the launch view as of iOS 8. I believe developers can use either LaunchImage or LaunchScreen.xib. Unfortunately, I couldn't find any document describing how to deal with LaunchImage after LaunchScreen.xib was introduced. I always got a black screen when I tried to use LaunchImage as the launch view.
My solution is:
Don't think about LaunchImage. Use LaunchScreen.xib. (You have to keep an empty LaunchImage in your Asset Catalog though. I believe it's a bug.)
Drag an UIImageView to the xib and make the UIImageView full screen. Remember to take the size classes and constraints into account.
Set an image whose resolution is enough for iPhone 6 plus to the UIImageView.
Check your all images and see if it is properly placed in the Asset and properly named and sized.
Also check which orientations your are allowing and accordingly add images to the asset.
I had the same problem.
I had to make a workaround: used the Default image for all iOS versions and DELETED the UILaunchImageFile key from info.plist.
I cannot use different launch images for iOS 7 and previous versions, so, I had to use the same "artistic" image for all, instead an image that mimic the first view of the app (which Apple recommends and I prefer), but at least I do not get the black screen anymore.
It looks like the UILaunchImageFile key that allows to use differents launch images for iOS 7 and previous versions is not working properly for Retina iPad in iOS 7.
WARNING: I am still testing the app, so I don't know if could be some side effects.
I also faced the similar issue but its solution was simple (in my case).
All I did was following -
1.Add a new file (if you have not added it) Launchscreen.storyboard
2.Get a UIViewController, mark it as Is Initial View Controller then add a UIImageView in it and set a picture which you want to display during launch of your app. Make sure you give this UIImageView required constraint.
3.Go to Project->General->App Icons and Launch images and select Launchscreen.storyboard as Launch Screen File (There will be a dropdown for it).
Because of iOS 13 and later, app launch different than earlier versions.

I simply forgot to call super.loadView() in my view controller...
override func loadView() {
super.loadView()
}
I added "Default.png, Default-568h#2x.png, Default#2x.png" these three files in my universal project for splash image, I have three diffrent image and the resolution exactly the same as mention in apple docs, for iPad 768 * 1024 , for iphone-4s -> 320 * 480 , for iphone 5-> 640 * 1136.
But my problem is that when I rum on iphone4s- iphone5 the splash rum properly, but when I run on Ipad the Deafault.png splash not showing instead of it takes reference from Default-568h#2x.png. The Default-568h#2x.png is showing on the iPad instead of Deafault.png and the image got blur and shrink on ipad also, beacuse Deafault.png not showing. How to slove this problem.
Any Idea or suggestion from experts would be highly welcome.
Launch image naming should be similar like this for universal application.
iPhone > Default~iPhone.png,Default#2x~iPhone.png & Default-568h#2x.png.
iPad > Default-Portrait~iPad.png,Default-Portrait#2x~iPad.png,Default-Landscape~iPad.png,Default-Landscape#2x~iPad.png
Please refere the following link for more details regarding image resolutions
http://developer.apple.com/library/ios/#documentation/userexperience/conceptual/mobilehig/IconsImages/IconsImages.html
and for image naming conventions use the following link
http://developer.apple.com/library/ios/#documentation/iphone/conceptual/iphoneosprogrammingguide/App-RelatedResources/App-RelatedResources.html
First I would like to suggest that,
Preapre all Images,
Select Project from Project Navigator And Go to Summary and scroll down this
screen appears, then right click on that and choose file from your
computer it will automatically copied to project and it will entered
in plist file also..
if your application is universal then you have
to set for iPhone and iPad Both.

See the offical document at chapter App Launch (Default) Images:
App Launch (Default) Images
Only you should do is set the launch image a proper name with relative size, then add those images to the project. Xcode will help you to display it correctly when app launching.
I am writing my first dual app and cannot figure out how to give tell it about the 2 icons to use
I read the following documentation
To specify the icons for your app, add the CFBundleIcons key to your app’s Info.plist file. The contents of that key include a list of filenames intended for use as the primary app icons. The filenames can be anything you want, but all image files must be in the PNG format and reside in the top level of your app bundle. When the system needs an appropriately sized icon, it uses the information in the key to choose the image file whose size most closely matches the intended usage.
I cannot figure out how to do this.
As Dan mentioned, you only need to drag and drop your images into the proper boxes (iPhone icon box, iPhone Retina icon box, etc).
You'll need the PNGs in the proper size, though. You can find information about sizes at the following link: http://developer.apple.com/library/ios/#documentation/UserExperience/Conceptual/MobileHIG/IconsImages/IconsImages.html
Also if you are using images for your elements (UIButton, UINavigationBar, etc), it's a good practice to name *#2x.png your retina display artwork, like:
navBarBackground.png <- Normal screen
navBarBackground#2x.png <- Retina screen
Edit: This way, your application will automatically use the proper image file with the proper screen.
If you are using Xcode 4+, then all you need to do is click on the project file at the top of the project navigator, then select the target you are building for, and then drag and drop your icon files into the appropriate boxes in the summary view
Everything is in the title but I have to make myself clear :
I don't mean : how to automatically change the background of the app once it has finished launching.
What I mean is : when you first launch the app, before the first view is loaded by the iphone there is a black screen. Is it possible to change this black screen which I get when waiting for the first view to appear? I'd like to put a picture instead.
Thanks!

You need to set a Default.png and a Default#2x.png (for retina) and all the work is done for you. Or if you have payed to be a developer, download xcode 4 gm, and you can double click on the loading screen area and you can have it named what ever you wanted.
Just add a picture called "Default.png" to the project (size of the iPhone screen) and it'll automatically appear.
You can add Default.png and it's variations to your project. This image will be displayed as splash screen during application startup (before the first view is loaded).
