This is an Xcode 6 Swift project. When choosing iPhone 5 or 5s in the simulator, the app launches at full screen height. However, when running the app on an actual device (an iPhone 5s), the screen is only iPhone 4 in height (i.e. black bars appear at the top and bottom of the screen).
The strange thing is that I've re-created this project from another test project - and in the original project I didn't have this problem.
I've performed a text-compare on the storyboard xml files for each, and both are mostly identical. I've also looked at the Build Settings for each, and can't see any obvious differences. Finally, the json files specified in the "Images.xcassets" directory for each are the same.
Managed to fix the problem. In the General settings for the target, under "App Icons and Launch Images" I clicked the "Use Asset Catalog" button and followed the options.
Place the Launch screen images for both iphone 5 and iphone 4 . Put the size of the default-568#2x image as 640 x 1136 .
May be you missed this size of splash screen in your project.
For me it was fixed after adding the images with all sizes
For me, this was because I'd saved the file in photoshop format, but with a PNG extension. The emulator loaded the file, but the actual device couldn't. Wasted 3 hours messing with asset catalogs before I figured it out!

I believe I am making a silly mistake. But I cannot figure it out.
I have an image named Default.png that I have added to my project. Now when I go to General and then Launch Images I drag and drop this Default.png to the 2x window for my app. When I go to build the project and try it, I get this error:
"The launch image set named "LaunchImage" did not have any applicable content."
What's the problem here? I've also seen that simply dragging and dropping the Default.png should do it, but I think that's for older versions.
Any ideas?
Thanks
Search for LaunchImage keyword in your .plist file and delete it. Then, try assigning the image again by dragging as you already did before...
This case raised in Xcode 5.0 + iOS 7.
Apple use Images.xcassets to group App Icons, App Launch (Default) Images in Xcode 5.0 + iOS 7.
For solving the problem of Asset Catalog Compiler Error
The launch image set named "LaunchImage" did not have any applicable content.
Approach:
Putting suitable size of images into LaunchImage.
For example:
Should be 640x960 dimensioning in iPhone Portrait iOS7 2x.
Should be 640x1136 dimensioning in iPhone Portrait iOS 7 R2.
Reference from iOS App Programming Guide:
Create and Set iOS Launch Images
Launch images are displayed while your app is launching on iOS. A launch image matching the device resolution appears as soon as the user taps your app icon.
App Launch (Default) Images
Specify the launch images for your app in your Xcode project settings. In Xcode 5.0, specify these images on the General tab of your project settings; in older versions of Xcode, this tab may have a different name. Xcode places your launch image files at the top-level of the app bundle and configures other project settings as appropriate. Specifically, Xcode adds the UILaunchImages key to your app’s Info.plist file automatically if your app runs on iOS 7 or later. That key tells the system the name of your app’s launch image files. For earlier versions of iOS, the system uses the launch image filenames to decide which image to load.
The same error has been resolved by adding the exact sizes of launch images for different iOS devices.
I tried everything here, deleted the .app and rebuilt each time, and nothing worked. I finally got fed up and switched back to the old style of launcher image specification (Project Settings Window -> General -> Launch Images -> Source -> Don't use asset catalogs.) That worked!
I had this problem as well. Make sure of a couple of things:
Aspect Ratio is what Apple expects, in other words square
The sizes are correct, 60pt (for example) should be 60x60
60pt #2x should be 120x120
After I fixed the sizes the app compiled without errors but I think the most important thing is the aspect ratio.
In my case, with Xcode 7, the Images.xcassets was missing from the Build Phases, under Copy Bundle Resources. Then I just added it manually and the problem was gone.
Try looking at the code for "LaunchImage" and rename it to "Default"
Check and compare carefully if your image size matches the expected size. In my case I was using a wrong size, but when correcting the project built fine.
Check this attached image to see where you can compare them
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 have a quite simple question concerning the difference in screen size between the iPhone 3/3GS and the iPhone 4. I've googled around, but was unable to come up with a good explanation.
Here's the thing: tabbar icons. All my icons are 30x30 and 60x60. I named the high resolution ones like [icon]#2x.png. When I load my app on my own iPhone 3GS, all goes fine. But when I load the app in Simulator, simulating a 4 with retina-display, the icon looks pixelated and is clearly the wrong resolution.
What am I doing wrong? These were the exact steps I followed, but I'm probably missing something. Is there something like an option I need to set in the plist?
Any help is greatly appreciated!
Kind regards,
Reinder
You need to name the icons as you have and edit your plist file
The following link should help
http://developer.apple.com/library/ios/#qa/qa2010/qa1686.html
Make sure you clean and build and remove the existing application from your phone and the simulator to see the results
The complete set of icon sizes distilled is
Icon.png – Home screen icon for iPhone 3 (57×57)
Icon#2x.png – Home screen icon for iPhone 4 (114×114)
Icon-72.png – Home screen icon for iPad (72×72)
Icon-Small.png - Settings/Spotlight icon for iPhone 3 (29×29)
Icon-Small#2x.png – Settings/Spotlight icon for iPhone 4 (58×58)
Icon-Small-50.png – Spotlight icon for iPad (50×50)
iTunesArtwork – Icon for iTunes AdHoc distribution (512×512)
It seems that you're doing it the right way. Did you try to remove the app from the simulator? Clean up the project? Re-import the icon image files?
Try (with the simulator stopped) cleaning all targets and re-building. Sometimes xcode gets dumb about what files it's got and needs to be told to clear its cached build and start fresh. It's in the "build" menu, or ctrl-shift-K.
I'm trying to give my iPhone a splash screen.
I've placed Default.png in my resources group. When I run the simulator it is displayed as expected, however when I install my application to the iPhone, no splash screen is displayed.
Does anyone know what the cause/solution to this problem is?
Thanks!
If Default.png is not showing up in device, but simulator... then try the following.
Be sure you delete any "default.png", "Default.png", "Default.PNG", etc. that you might have created in several wrong attemps from within XCode and in Finder.
Delete the App on your iPhone/iPod/iPad
In Xcode Build->Clean All Targets
In Finder go to your project and locate the build folder, delete all folders in there.
Create a new Default.png like in the following example:
Connect iPhone/iPod to Mac.
Start your App on iPhone
In XCode launch Organizer (Window->Organizer)
Select your connected Device
You should see a tab "Screenshots"
Push the Capture Button, to make a Screenshot of your App
Push "As Default Image..." Button (This will create the Default.png and add it to your project, so that's a really handy thing)
Build and Run again. It should work now
Problems can occur due to wrong format (should be 320 width and 480 height (yes, that means you can see the status bar in your default.png)) or because you might have named the first file default.png (WHICH IS WRONG), which worked in simulator because it seems to be case insensitive but then when it gets copied to iPhone, it won't be found, cause it is case sensitive. So it will still be there in build folder (i think) causing a next correctly named Default.png not to override the old default.png in this iPhone build folder and so it might seem, that you can't fix the problem (cause you see Default.png in project, but in build it's still default.png).
At least this is my understanding now (afterwards), since for me it simply didn't want to work even though I tried again and again with different solutions from other people.
So from my point of view this different file handling (case/not case sensitive) is a mess that you can solve, by simply cleaning all and everything and trying to generate a new Default.png with the organizer (after everything was cleaned).
If you want a different/modified splash screen. Open the generated Default.png with photoshop/gimp/whatever and edit it.
Make sure your image is 480x320 pixels, and placed in your application at the top level. The frameworks will display this image until your initial view has loaded and is ready for display.
If you are seeing a black background then there is something amiss, however if you are just seeing your app's initial view then be happy you have managed to launch your app and have it ready for use in good time.
If you really, really want the user to to see your splash screen then slow down your launch by adding a delay into your app before you present the initial view
The file name must be Default.png (with a capital D). Also, do a clean/rebuild of the entire project to ensure the most recent version of the file is being included in the project. Check the filename on the filesystem, it may display differently in XCode.
Make sure that is is added into the bundle. To do this, select the image in the XCode left navigation panel, get info on the file, and make sure the checkbox for your target is enabled. Also make sure the file is really a png and not just named that way.
Just check the spelling ... I think u r using "default.png" instead of "Default.png". just make "d" capital "D" of Default.png .
Another possible issue that is Default.png is actually Default.jpg that was renamed to .png.
This will work fine on the simulator, but won't work on the device.
If you are using an iphone 4 you also need to add a
Default#2x.png with the size 640*960 px.
That's what fixed it for me.
This naming convention applies to all images in your app btw.
I had a similar problem, but my images were being displayed as gray or gray bars. It turned out that there was an alpha channel on the PNG images that the simulator was having no problem with, but the iphone wouldn't display. I opened the images in preview on my Mac and re-saved them without the alpha channel and everything worked. Don't know if this is your problem, but it might be worth a try.
I know this is old, but I'm having the exact same issue. The image doesn't show on the device, but is fine on the simulator. I noticed a lot of really weird things with my project, like there were 3-4 "Default.png" images in my plist and that there were a few other "Default.png" images in different libraries and stuff that I didn't notice.
I tried everything to get them to show up, but after creating a new project and setting the launch images to the EXACT same images I was trying to use, they worked fine. The only thing I can think is that somewhere the project gets corrupted and won't figure out what those launch images do.
Had the same problem caused by saving the initial file as default.png, so it should be Default.png (normal) and Default#2x.png (retina) images.
Go to your projects plist and add a row "Launch image" - use a different file name. Save your images with this name (and add #2x.png for retina). Should be fine afterwards.
Also, if you've already install the app on device, delete the app from device (as previous installation may not affect the changes).
