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'm looking at the iPhone 5 specs, and see that the screen resolution is 640x1132 or so, which would break some of my manual+storyboard interface layouts. I'm wandering how to make an app so it would either show on iPhone 5 in 640x960 screen (with black bars), or exclude my app from sale to iPhone 5 at all, as I do not want to worry about the interface breaking. Is this possible for existing apps?
Thank you for your input!
Unless you include a Default-568h#2x.png image in your application, it will not run at full iPhone 5 resolution.
In the Apple keynote on the 12th Sept 2012, they said all current applications in the app store would run on the iPhone 5 with without a problem using the black letterbox at the top and bottom.
The way to remove the letterbox is by providing a Default-568h#2x.png image, like duskwuff mentioned. If its not there, the device will run the application will run at 640x960.
I've seen tons of questions and answers regarding merging an iPhone and an iPad app into an universal app, but that isn't what I want to do. What I am going to do is use in app purchase to unlock an iPad interface and then display the correct interface using conditionals. If the interface is purchased, the app displays the iPad Nib, and if not, it just displays the same way as an iPhone application does (with the option to scale the app, etc). The conditionals are very simple and I have already implemented them, however the issue I run into is this: If the IAP is NOT purchased, the iPad displays the iPhone Nib, but not in the typical way. It is just in the corner with no option to scale it, rather than in the center with the black border that you usually see. Does anyone know how I can set it up so i fixes this issue? I'm a little stumped to be honest.
The Info.plist file in an iOS app contains a key, UIDeviceFamily, which lists the devices that the app natively supports. If the key's value is 1, or a array containing 1, the app natively supports iPhones and iPods Touch. If the value is 2, or a array containing 2, the app natively supports iPads.
If UIDeviceFamily says the app supports iPads, then it will run the app in native iPad mode, not in iPhone-wrapper mode.
The Info.plist file is part of your app bundle, and you can't modify files in the app bundle.
So there is no way to enable or disable the system's native-iPad support at runtime. You'll have to move your app's top-level view into a wrapper view that centers and scales its child, and use that wrapper view as the UIWindow's subview.
UIDeviceFamily in the Information Property List Key Reference
This isn't possible, unfortunately. The iPad will know that the app is iPad ready and will tell draw the screen at full size. Even if you showed iPhone xib file on the iPad, they would still be scaled to fit the full screen using the UIViewAutoresizingMask params you've set for them.
One thought would be to force the size of your UIWindow to be iPhone sized (remember to account for retina) and centered, but I'm not 100% sure how/if this would work. You may have to change each UIView frame. I'm not sure.

I have developed a straight iPhone/iPod Touch app.
A launch image is implemented for Retina displays as well as the lower resolution of the former generation devices.
Those images are displayed properly on the iPhone simulator as well as on several iPhone an iPod Touch devices.
However, since some days, when launched on an iPad (1) or iPad simulator one of the other images within the app is shown.
Apparently the image that is displayed wrongly, is one of two amongst ca. 70 images within the app. Those two images happen to be either
1. the first image in my xcode project groups hierarchy.
-or-
2. the first image in my project in alphabetical order.
I did not yet find a pattern of when 1. or 2. happens, so when the first image in the project's hierarchy of groups is taken or when the first in alphabetical order is taken. But it seems to be one of these two files only.
Any idea what I probably did wrong so that a wrong image is picked as launch image of this iPhone-only app whenever it is launched on an iPad?
Thanks in advance.
Cheers

Try inserting an image named Default.png into Xcode. That's all, just drag it in. Xcode recognizes any picture named Default.png as the loading image. That should make it work.
To expand a little on Jack's answer - you can indeed use an image named Default.png which will automatically be used as a launch image for your app.
However,you can also customise the launch image for particular hardware and device orientations by using images of a particular size and name - for example, a 768x1004 pixel image named Default-Portrait~ipad.png added to your project will be automatically used as the launch image when you launch the app on an iPad in portrait orientation.
The use of these customised images is highly recommended, as it allows the launch image to be sized appropriately for the different shapes of screen (i.e. iPhone and iPad), and allows high resolution launch images to be used on Retina display devices.
For a list of these sizes and image names, see this page. The items of interest are the ones beginning with "Default"
All iPhone apps have a splash screen, or what Apple refers to as a “launch image”. It is the screen that is displayed immediately after you press your app’s icon on the home screen, while the app icons are sweeping away and your app is zooming into view.
Some apps opt not to display a splash screen and go for a black screen, which is the default behaviour when you create an app. Others display a wireframe of the app’s interface in order to look like it is loading faster. See Apple’s native apps such as Clock and Camera for good examples of this. The most common use of the splash screen (especially in games) is to present a company or game logo, as we do in Addicus:
Apple has made it so easy to set your splash screen that you don’t even need a single line of code to do it. Why, you don’t even need to change a setting. Here’s how to set your splash screen it in just 2 steps:
Add a file to your project’s Resource folder called Default.png.
There is no step 2. Take this time to reflect on how good life is.
And that’s it. Run your app and your splash screen will zoom into glorious view.
A couple of things to watch out for when working with splash screens:
Whatever image you give it will be scaled to fill the 320×480 resolution of the iPhone, so ideally you would use a 320×480-sized image.
If your iPhone app is running in landscape mode, you need to rotate the splash screen you use. For example, our splash screen is rotated 90 degrees to the right in the above image.
