I am working on a Xamarin.iOS app. We have an issue where our LaunchScreen sometimes do not load the image we are displaying in it. The bug is very transient and it only happens sometimes to certain users.
The thing is that when the image first is loaded on a device, it always shows up. On the other hand, if the image is not shown on a device, you can restart the app several times without it being loaded. Sometimes it helps to reboot the device. Sometimes an update/reinstall fixes it, sometimes it does not.
The image resource we are loading is not included as a On-Demand bundle resource, but is included in an Asset catalog.
I have been struggling with this bug for a while now. Sometimes I think I have fixed it, but then it suddenly shows up again.
I do see my launch screen being loaded, since the background color I have on it is displayed. It is only the image I am having the issue with.
I've seen this post, but it doesn't seem to be the same issue, as what I'm experiencing is in the production build from the app store. In debug builds, the splashscreen is loaded fine every time
UIImageView missing images in Launch Screen on device
Anybody who can point into the direction I should look at? I can share some code for the xib launch screen or the asset catalog's json file if necessary.
I know this question may seem like a duplicate of a few existing ones but its not.
I am struggling with this issue where universal (iPad/iPhone) application does not display the splash screen anymore.
Before upgrading to iOS 9 and Xcode 7, no such issues were present. After upgrading no changes were made to the splash screen in any way.
Tech data relevant to the question:
Supported devices are iPad (landscape only) and iPhone
(portrait/landscape)
I use "Launch Screen.xib" that has an UIImageView with size classes and
constraints set up so that it's always full screen.
I have added all splash screen images in image assets (except iPad
Portrait ones)
I use Xcode Version 7.0.1 (7A1001) and iOS 9.0.2
This issue does not happen on an iPad
The wrong splash screen looks like this on iPhone 5s:
This is made in portrait mode, so there are white squares on top and on bottom of this "black square".
I was struggling with this issue yesterday but I managed to fix it by renaming my launch screen to "LaunchScreen.xib" (without the space). But this morning the issue re-appeared.
Things I've tried:
Removing and creating LaunchScreen.xib again with and without space
Creating LaunchScreen.storyboard file instead of xib
Adding #2x and #3x versions of image used in LaunchScreen.xib
Removing/adding/replacing images in image assets
Cleaning, build cleaning and even deleted derived data
Restarting device, reinstalling app, relaunching without building and many other solutions that I could think of.
Nothing helped, so maybe someone fixed a similar issue already and can lead me to the right direction.
EDIT 1
So I renamed my LaunchScreen.xib image used from "Default.png" to "DefaultSplash.png". This instantly fixed all issues on iPhone. But now I have a new problem - iPad splashscreen is now black. If I set the LaunchScreen image to some other image used in project, the Ipad displays it as splashscreen without any problems, but neither Default.png nor DefaultSplash.png can be used on ipad now. This is really weird issue.
In my case the images in the "Launch Screen.xib" weren't displaying. I had to rename them and reset the new names in the nib file to make it work.
So I fixed the issue like this:
Since I renamed the file LaunchScreen.xib, it fixed an issue on iPhone but caused a similar problem on iPad. Since then, I cannot use the same image file name for the same xib (i.e. if image "Default.png" failed, it cannot be used anyomre... Bug?). So I created two files, LaunchScreen.xib and LaunchScreen~iphone.xib with separate image files for each. Now it works okay.
Seems ugly and buggy but it works.
There is a change in Xcode7 iOS 9 onwards. They have modified Launchscreen(Black screen we will get).If you change deployment target means you can see the previous launch screen. Only empty view controller is present so we have make changes on it.
As per requirement in assets add images in imagecassets.
It may sound stupid but something related to this scenario may happen:
If you hook any outlet and then break it by changing the custom class you will get this black screen behavior without any warning, instead of the typical crash from any non launch storyboard/scenes this will lead to a black screen before the app start.
I'm testing my app on a physical device (using a provisioning profile). The device is an iPad Air 2 with iOS version 8.1.
My App wasn't appearing full screen, so I managed to get it full screen following the advice to add Default-568h#2x.png to the project, as per this thread:
Why [UIScreen mainScreen].bounds] is not returning full screen size?
However, upon adding it to images.xcassets, I see this:
Question 1) Why is Xcode complaining about a Missing Default-568h#2x.png launch image when it's clearly there?
So anyway, this made my app start full screen but the launch image was not appearing. Instead, just a plain black screen was showing up during app load.
Question 2) Why wasn't the launch image showing up?
I deleted all the launch images that were eventually added in an attempt to get something working (because this is iOS and trial and error seems to work way more than a logical process). So at the moment, no launch images exist in images.xcassets. However, my app still runs full screen. I removed the already installed app from the device (by making the icon wiggle and tapping the 'X'), selecting Product>Clean from Xcode and building again. No luck. App still appears full screen on future runs. I then attempted to follow the answer by EliSKoren on this thread:
Launch image doesn't update
However, the only reference I could find to launch images were for simulators, not physical devices.
Question 3) Trying really hard not to loose it ... What's happening!? Why is my app still appearing full screen even though I've removed launch images?
This is because Xcode provides placeholders for different devices and respective to them being retina or non retina and device sizes.
As you can see your image is on a placeholder as "unassigned", So xcode cant figure it out which device it is for, hence the image is not showing.
To correct this here is a screenshot --
EDIT
Please migrate to get the launch image assigned to the assets from here
Click on Launch Image Sources -- Use assets catalogue and the pop up will show and then click on migrate.
As you can see in the attribute inspector, you can choose which device launch image you want and it will give you that.
Check by clicking the place holder what image size or resolution it requires and then you just drag and drop those images from finder.
Hope this helps
Edit Final
As it turned out OP was using cMake for the xcode project and by default xcode had already a launch image asset JSON installed which had a wrong configuration, Thus creating another Launch Image wasnt overriding the existing JSON as for cmake the earlier config was being loaded. And by default Universal devices was selected but the Device orientation was totally unchecked.
Checking device orientation after getting a clean version of the project and letting Xcode decide its default Launch Image assets and filling up images in that JSON fixed the issue with OP. Further discussions are mentioned in the link in the comments.
I have an app that supports iOS8 and later, built in Xcode 7 and I am using a XIB for a Launch Screen (I do not have launch images). The view contains a single UILabel with the app version, and 2 UIImageViews with images that are both present in Images.xcassets: A logo and a splash image.
The UILabel and the logo image appear correctly when I launch the application, but the splash image does not if I run the app on an iPad Air 2 with iOS9. I have tested on an Air and a Mini running iOS8, and iOS9 simulators for iPad 2, iPad Air, and iPad Air 2 and the image appears correctly in all of those.
I ran some basic troubleshooting to see if I could figure out what is going on but I haven't been able to solve it and the only difference I can see between the image that's working and the one that's failing is when I added it to the assets...
Here's a rundown of what I know:
The UIImageView for the splash image is in the correct place, at the correct size. I can tell this because I set its background color to green just to make sure. The view is there, but the image does not appear. So I'm assuming that the view is not to blame.
Setting the UIImageView for the splash image to also use the logo image makes the logo image appear in the correct place for the view. This also leads me to assume that the view is not to blame.
The UIImage that I am using in the splash image view is used elsewhere in the app and appears fine in those other views (the logo image is also used elsewhere in the app and appears fine). So I'm assuming that the image is valid and having it appear in other views is not a problem.
I've confirmed that the settings of the UIImages for the logo and splash in the xcassets file are the same. They are set to Universal, Any width and height, multiple scale factors, rendered as default. There is one difference - the logo has 1x, 2x and 3x scales while the splash image only has 1x and 2x, but I have also tried using UIImages with only 1x, and 1x and 2x values in the UIView and they work (if they were added to the project some time ago).
Adding another image of a different size or format (PNG and JPG) to my xcassets and using that UIImage in the UIImageView for the splash image also fails to display.
Adding another UIImageView to the XIB file and allocating it a UIImage that was already in the xcassets works, the image appears in the loading screen.
Copying and renaming the image files used for the logo and adding them to the project then using that UIImage in the splash view also fails to display.
I have tried cleaning the project, restarting the development machine, and deleting the app from the Air 2 and reinstalling it just in case that was a problem.
These last three steps lead me to believe that there's some issue with images added after a certain point in the project file's lifetime. While I updated to Xcode 7 yesterday, the splash image was originally added in Xcode 6, but the logo image (also added in Xcode 6) was added some months before.
I've looked over the json files for the logo image and splash image and they appear to have the same format. I've also trawled through the pbxproj file looking for differences and I can't see any.
So I was wondering if anyone had any idea why the launch screen might not display these new images I'm adding on the Air 2 specifically? Other questions I've been reading through relating to images not appearing all seem to relate either to Launch Images, or to images in XIB files that have associated classes, neither of which seems relevant here.
Turn it off and then on again.
Seriously, restart the device — that’s what fixed it for me.
Here’s what didn’t work:
Cleaning DerivedData.
Cleaning the project.
Uninstalling the app from the device.
Restarting Xcode.
Restarting the computer.
Older observations:
Just like the others, it:
Works fine in the Simulator
Used to work on the devices (iPhone 5S, iPad Air)
No code changes (verified via git reset --hard HEAD), yet stopped working.
What I remember triggering the first build where it stopped working was unplugging the iPhone while it was runnning. (Not sure if it’s related.)
However, the git reset not fixing it (combined with all the clean steps not working) tells me it this must be getting cached somewhere else. Quite possibly in one of the .gitignored files? (I’m using Git ignore file for Xcode projects)
One workaround that worked for one UIImageView (in the UIView that has three) but not for the others was putting the image into an .xcassets file. Reverting to the plain image file did not undo the fix. (Really feels like a caching error.)
UPDATE: See top — restarting the device is what fixed it. I get the feeling the wrong bitmap data is being cached on the device itself.

"The solution for me was simply to make sure that the "Clears Graphics Context" box is unchecked for the UIImageView in the storyboard. Just changing this fixed it for me."
No other solutions worked for me.
Got it from apple developer forum
I had exactly the same issue on an iPhone 6.
The very strange fact is that I was able to use another image from my images.xcassets which had the same size, compression, color space ...
I'm not able to find why it doesn't work but I found a solution :
Simply put your file outside your images.xcassets and use its full name (with extension) in Interface Builder
Hope this help !
The following sequence of operations fixed the issue for me on Xcode 7.3.1 and iOS 9.3.4:
Clean Your Build (⌘+⇧+K)
Close Xcode
Hard Reset iOS Device (Power + Home Button reboot)
Relaunch Xcode - let indexing finish and build on device once it is ready.
Many other answers suggest rebooting devices and / or rebuilding and / or reinstalling is the solution.
While these answers work for some of us, the reason these work is because the app is forced to "retake" or "rebuild" cached snapshots.
Cached snapshots are used by apps to present images before supporting data is loaded into memory, including the asset catalogue that contains storyboard images.
This SO answer by #jaga provides the solution, but not the reason, as to why UIImageViews are missing in the Launch Screen on device (but not in the simulator).
Background
Recently I attempted to use a custom font in my "Launch Screen.storyboard" file.
The reason I could not became clear after reading this SO answer by #TimCamber, which prompted me to do a little more research and testing.
The reason that a custom font is not included in my Launch Screen Storyboard file is the same reason an image within an asset catalogue is not included...
The app prepares portrait & landscape snapshots of the app's Launch Screen from your Launch Screen Storyboard file and (currently) saves it in your app bundle here:
/Library/Caches/Snapshots/<<app_bundle>>/ and
/Library/Caches/Snapshots/<<app_bundle>>/downscaled/.
This process is complete before any supporting files are loaded, including any custom fonts and the asset catalogue.
Solution
As mentioned above by following #jaga's solution, literally all that is required is to:
(old school) add an image file (.PNG) to your app's bundle (as you can see from the screenshot below I added the image file under the Supporting Files subdirectory in an Images subdirectory), and
reference that image in your UIImageView object in the Launch
Screen Storyboard file...
I was seeing the same problem. Rebooting the device (iPhone 6) and rebuilding the app to the device is the only thing that fixed it. I tried many other tips and suggestions but nothing else worked. Only reboot + rebuild helped.
My solution #iOS 11.x:
Use .jpg image instead of .png. I think image file size matters;
(Optionally) Put image file in project directory rather than .xcassets;
I had the same for app installed from TestFlight.
Delete app -> then restart iPhone -> then reinstall app works for me.
Just reinstall app or just restarting device didn't help.
What worked for me was to select Reset Content and Settings... from the Simulator menu
I was having the same problem, but restarting the device didn't help. What worked for me was deleting the UIImageView from my launch storyboard and adding a new one.
Have you tried turning the device off and on again? Do it.
Bring images out of Image.xcassets and add them again to project. It worked for me.
Remove app from mobile and then restart mobile and install app again. now the issues will be solved
I also had this exact problem in Xcode 7 with iPad and iPhone devices. Although it makes no sense, I was able to get around it most of the time by setting not only the Image but also the Highlighted image in the image view to the same image in my images.xcassets.
I use the iPhone 5s device, also meet this problem.
I fix it by :
Remove Drive Data
Clean the project
Restart Xcode
Remove the project from my device
Restart the 5s.
I think it's something wrong of Xcode to use memory, system may be allocate a little memory for Xcode cause Xcode drawing the lunch image failed (On my computer , Xcode have runned for several weeks without close)
it's worked for me.
First in xcode clean de project.
If you use the simulator, delete app and relaunch.
If you use a device, delete app and restart the device.
I think launchscreen only support image in Assets.xcassets.
Restarting Xcode did it for me.
What did not do it:
Clean build folder
Restart device or simulator (image wasn't visible on either)
Select the ImageView and then remove the image extension (.png or .jpg) in the attributes inspector tab > Image view > Image > Image Name.
On launchscreen.storyboard the image will not appear but it will be there in device. This worked for me.
It seemed a bug of iOS. Like sometimes the system animation disappeared.
Now I just reboot the iPhone and it is worked for me.
In my case I it was the image name.
I added an image named Default-568h#2x.png to LaunchScreen.xib - one of my old launch screens just for testing purposes. I was building on the iPhone X Simulator, the image didn't show up.
Changing the name to something neutral (MyImage.png) solved the issue.
It seems that the #2x was part of the problem as well as the -568h.
Which makes some sense on a -812h#3x device.
I have the same issue with imageView a launch screen storyboard. I removed reference of picture from project, I renamed my image and added it again to project. All works perfectly.
Also can 1. delete project image 2. change image name 3. add file image to project
It worked for me.
I had this problem in iOS 10 on an iPhone 6 and also in the Simulator. My image was in a folder and that seemed to be the issue. I removed the image from the folder in Xcode and put it in the project's base directory which solved the problem.
I experience the same. I change image resolution from 300 pixels/inch, change it to 72. It works for me.
Next helped to me:
change "Launch Screen File" to another xib
run the app
change xib back
Also very important: check that your is xib not opened in another tab, that can cause it as well!
I found a simple but radical solution that worked for me :
1 - Delete the file : LaunchScreen.storyboard and move it to trash.
2 - Product -> Clean
3 - Create a new launch screen file named : LaunchScreen.storyboard and put your images in it
4 - Save and build
That worked for me after trying complex methods for hours... It seems that my LaunchScreen.storyboard was write-locked and couldn't be saved or a weird caching process was blocking it.
This is too important
Must be empty! Launch Screen File
Image name is the problem.
Rename the image name used inside the Launch screen storyboard.
Make sure not to use any character other than alphanumeric ( don't use "_-&#")
Worked for me like a charm..
SOLVED!
The only thing that worked for me was deleting the ViewController from LaunchScreen.storyboard and create a new ViewController set to
Is Initial View Controller
Simple as that :)
I'm trying to get the Launch screen to display instead I get the default black screen.
I remember I've had this issue in the past and is something really silly but I can't remember what it is.
I have a LaunchScreen.xib. I've set in my target -> info to use LaunchScreen and not image catalog. I am running iOS 8 and using Xcode 6.1. I tried on all iPhone simulators and iPhone 4s.
I can't think what more info to give than that.
For those who are still looking for another answer here's what worked for us:
Our launch xib only contains an imageView in the middle of the view. For some reason the image never showed (but the view was there, checked it with changing the background color).
The solution was to move the image file out of the image catalog and just drop it in the project as a standalone file. Pretty strange considering when we tried other images from the catalog they appeared correctly but not this one. Anyway, I hope this helps someone!
I had the same issue.
Turned out that I had earlier tried to attach a viewcontroller file with the launchscreen. To fix:
Go to launch screen
Click Connections Inspector in right pane
Remove all connections.
Accoring to #doctorBroctor: also go to the File's Owner tab and remove the connections there.
Go to your launch screen
Go to file inspector
Check the checkbox for "Use as Launch Screen"
I have tried with:
Deleted Launch Screen File.
Tapped on Use Asset Catalog in Launch Image Source and added Splash screen Images as desired in the image asset.
Deleted Previous Project on Simulator or Device. Clear the Project.
Run Again and it is showing now.
One reason for why you might experience the black screen instead of your launch screen is that the .xib file might not get copied in your build phase. At least that was my issue that caused my app to show the black screen even though I had done the steps you describe.
So, double check that your LaunchScreen.xib (or whatever it is named) appears in:
Your target -> Build Phases -> Copy Bundle Resources
And if not, make sure to add it. That resolved my issue.
For me the problem was that I hadn't selected the LaunchScreen.storyboard in the General tab of the project settings.
I've experienced the same issue. The solution for me was simply delete the app, reboot the device, then reinstall it. I think iOS caches the Launchscreen, and this cache is not invalidated every time when it should be.
I had the same issue in iOS 9 as well. Deleting the old app in simulator alone is not enough. Simulator has to be quit launched. It worked for me.
I fix it by select the "is Initial View Controller" in storyboard.
Make sure to delete the installed app from the emulator. Then run the app again from xcode (product->clean, product->run).
That worked for me.
I've looked at all the above answers, it helped a bit. Especially the answer by Suragch put me in right direction.
The LaunchScreen.storyboard isn't showing up, even after applying simple background colour to the view and removing the image.
Firstly, I cannot see the "LaunchScreen.storyboard" as shown in the image
This was because, some reason the LaunchScreen.storyboard wasn't added to the build Target.
Solution: Ensure the LaunchScreen.storyboard is included to the build Target.
Also, Choose the LaunchScreen.storyboard from the drop down as shown in above pic.
I hope it helps someone!
I found this old post 'cause my launch screen WAS working, then it stopped. I thrashed around for a good while and then realized this, undocumented problem:
If your launch XIB or storyboard file has a UIImageView with an image whose name contains a space, the entire screen won't load.
I only had a centered UIImageView in my LaunchScreen.xib that contained an image (.png file), and had the same black screen showing.
I removed the image (the .png file) from the project, added it again with new name, and used the new image.
Make sure to use empty Launch Screen File, then Xcode would use Launch Image Source.
Make sure you have "is initial View Controller" checked in interface builder.
I tried pretty much everything else but this finally fixed the problem and now it works in simulator as well as the device.
New feature in the iOS 8 SDK: you can now use a storyboard scene in place of your app’s launch images.
Create a blank storyboard file named LaunchScreen.storyboard.
Go to your target settings and, on the General tab, select the storyboard as your Launch Screen File. Xcode will add a corresponding UILaunchStoryboardName key to your app’s Info.plist. When this key is present, Xcode will prioritize it over any launch images you might have set.
Add a view controller scene to the storyboard. Add some subviews to the scene and position them with constraints. When you launch the app on a device, the OS should use the scene as the launch screen.
For more information check out this blog post by Ole Begemann "Replacing Launch Images With Storyboards".
Reset Simulator working for me
For iOS 14 and newer:
Device > Erase All Contents and Settings...
For iOS 11 and newer:
Hardware > Erase All Contents and Settings...
For previous versions:
Simulator > Reset Content and Settings...
Your launch image should be a PNG. A JPEG may work under certain targets, but you should use PNG anyway.
