The final step of my first iphone app (Xcode 6) is to add a launch (splash) screen. I copied a 640x960 (iphone 5 ios8) into my images.xcassets file, into the LauchImage space. I copied into the 2x location (for iPhone Portrait iOS 7,8). I am only running this development app on a single phone so won't need to support all the various screens/sizes.
Apparently, just dragging the image into the .xcassets file/LaunchImage isn't sufficient. I still have only a one sec black screen flash while my app is loading, and no launch screen. Is there another step or two needed here?
thx.
In your app settings General page try setting the Launch Image Source to "Use Asset Catalog".

I have only Default-568h#2x.png and Default-568h#3x.png in my bundle. When I execute the application in iPhone 6 and 6 Plus the app automatically does some scaling and displays the app utilising full screen size.
But when i use some .xib file as "Launch Screen File", the app stops scaling and does not displays for full screen, has various UI issues.
Is it mandatory to have launch file, if I need to support iOS 8 / iPhone 6 / iPhone Plus?
Is there any chance for the app to get rejected if the app does not use LAUNCH FILE?
Please let me know your comments.
You can use your storyboard for your launch screen now.

NO.
LaunchScreen xib is a quick way to detect main screen.
Depending upon the main screen, OS runs your app and determines screen width and height.
Another approach is just to add launch images for iPhone 6 and 6 Plus instead of LaunchScreen file.
NOTE: Apple is motivating to use LaunchScreen, because it is a one file launch image. It can also be used for pads as well. Single file multi purpose.
I have a simple out of box app that doesn't use the entire screen when I deploy it on a iphone5s. By default it creates a LaunchScreen.xib. I have not edited this file on purpose.

Other answers suggest to add a Default-568h#2x.png launch image, but I am not using a launch image, and I am not sure where to add these. I see a place for this in the Images.xcassets by clicking the + icon and selecting New Launch Image.
Do I need to add a New Launch Image to Images.xcassets? If so what is the point of having a LaunchScreen.xib?
Thanks!
To get the app to display full screen:
As suggested here (https://stackoverflow.com/a/15328339/4347877), you must include a Default-568h#2x.png launch image (for iOS 7 or earlier). Or if your deployment target is iOS 8 or higher, you have the option of using LaunchScreen.xib.
Why Use LaunchScreen.xib?
For iOS 7 and earlier, app developers had to provide separate launch images for all screen sizes, resolutions and orientations their app supported. For universal apps, up to seven images were required: retina and non-retina versions for 3.5-inch iPhones in portrait and for iPads in portrait and landscape; and another retina image for 4-inch iPhones (the iPhone requires no landscape version because apps are always launched from the portrait-only Home screen).
Creating these images is a nuisance. Xcode 6 comes to the rescue by allowing you to specify a storyboard whose initial view controller will then be used as the app’s launch screen.
If you want to add a launch image instead of using LaunchScreen.xib:
Click on your Images.xcassets folder, right-click in the left pane, and select "New Launch Image." Once you have the correct launch image sizes for all devices you would like to support, drag each image to its respective slot (e.g. "Retina HD 5.5" or "iPhone Portrait 2x"). Before Xcode 6 introduced LaunchScreen.xib I used to create my launch image size here: http://www.appiconsizes.com.
Okay the solution I found came from this question. The answer from James Nick Sears actually fixes my problem. This is after adding the Launch Images. It should be noted that launch images using the images.xcasset is the prefered way to do this pre iOS 8.0 and the only way to make your app compatible with devices running iOS 7 and earlier.
I suggest using TiCons to create the icons, the mapping took me longer then it should have to figure out. In xcode you can see the expected image size for each device by selecting the empty image box and looking in the attribute inspector window on right.
But the real kicker is clicking the 'use asset catalog' button on the "App Icons and Launch Images" of your apps settings under the General tab. Once you click Migrate you can select your LaunchImages from the selection menu that resides where the button used to be, after "Launch Images Source". Without doing this your app won't work correctly on pre iOS 8 devices.
I updated my application to use Image Asset for App Icon and Launch Images i set both with
appropriate image size according to Apple Doc. The issue that I have that for Iphone
and the simulator for (4S/5/5S) the launch image/screen is always black except for
Iphone 6+ but it works fine on iPad. I looked at couple of post here and nothing have
worked as follow
1) deleting the asset catalog and creating a new one
2) adding #2x and 3#x to each file before adding to the catalog
3) removing and redeploying the application
Anyone had that issue when porting image catalog ? Im using Xcode 6
Targeting ios 7 and 8
Thanks

Update 1
When disabling landscape launch screen appears normally
something i noticed before doing, so on either the device and the simulator
the application starts in landscape even if the device is held in portrait
and then it rotate to portrait. Still trying to solve that issue now
The following steps are worked for me:
Add the images to the project (root directory or Resources folder) with the following nomination (I will describe them into the Portrait launchimages): Degault.png (3.5 inch), Default-567h#2x (4 inch), Default-667h#2x (iPhone 6), Default-736#2x (iPhone 6plus).
Go to the target settings, App Icons And Launch Images on the General tab -> Set the Launch Image Source to not use asset catalog ('Do not use asset catalogs').
Remove the LaunchImage asset from your main image asset
Go to the target settings, App Icons And Launch Images on the General tab -> Set the Launch Image Source to use asset catalog
The XCode 6 is going to ask you about image asset migration from the existing images. Just click to 'Migrate'.
And it worked for me for each kind of devices on iOS7, iOS8.
Note:
If you check the new LaunchImage asset, than you can see it is really strange. It seems to contain only a few image without the images with iPhone6 or iPhone 6plus resolution.
I found that if I go to the app target general tab and remove all device orientations, the launch image will show again (i.e. the black screen goes away). After running the app, I then went back to the app target general tab and restored the desired device orientation and the launch images continue to work as desired.
(My answer should be in the comment section but I can't post it there due to my reputation)
May be these are very basic steps but:
Have you tried doing a full clean and deleting the derived data?
Have you checked the General tab of your target, under App Icons and Launch Images?
all!
I have a problem. I've created launch images for my app. I added them through assets catalog.
Ipad ios 6 and 7 works, but iphone works only for ios 6. Ios 7 on iphone shows only black screen (for all: 3, 3 retina and 4 inch), and then app starts, but launch image don't shows.
Yes, iOS6 and iOS7 require you to insert separate launch images for each… Actually, technically, the 2x iOS7 and 2x iOS6 iPhone launch images can be identical, and the R4 iOS7 and R4 iOS7 launch images can likewise be identical, but they are associated separately in the images.xcassets folder based on version.
To guarantee you have launch images associated with each version, go to Targets > General then go to "Launch Images":
Then select all of your supported devices in the right-hand menu under the 3rd tab (in this screenshot from my particular app, only portrait interface is available for iPhone, but if your app also supports landscape, landscape should show up here too). To find out the "expected size" of each launch image, select its placeholder then scroll down to look for the "expected size" also in the right-hand menu. And finally drag the appropriate images into the appropriate placeholder slots to make sure your app has launch images suitable for each device/interface.
I have faced same problem few days ago and i posted my Answer in this question-
iPhone application developed in X-code 5, not showing icon and launch image while running on iPad
Hope it help you.
I have developed an iPhone app, it is not universal. Now when i run it on any iPhone it's launching with splash screen and icon image is getting showed on device but-
when I run same app on iPad neither it is showing the launch images/Splash screen nor it's icon image is visible on device.
I am using Xcode 5, Deployment target is 6.0, and app is not universal.
Please have a look of images what i did yet.
what is the correct process in Xcode 5 to set icon images and launch images of any iPhone app, should i set it for iPad somewhere?
Is it because of resolution of images (Icon/Launch) for Retina and Non-Retina Display?
In X-Code 5 image assets is the folder to manage the images including icon images and launch images but in my case to manage it i just check the resolution of every icon image and launch image, some of the images having correct suitable size for retina display but not having proper resolution so i corrected it.
Resolution Non-Retina: 72
Resolution Retina display: 376
In image assets > icon folder > it worked for me when i put images with correct resolution and size i.e.-
Xcode 5 is smart enough to check the resolution so be sure about the resolution of images, I Think.
When i tried to add correct images in image assets > launch image, it didn't work yet so For launch image i used the old pattern to handle Launching image like-
It worked in my case, Hope It will help others as well.
I think you need tick the required device and need to add App Icons and Splash Screens using image assets like.
Here are the sizes required for according to devices.
Please review:
Remove app from simulator (Reset simulator), clean project.
then check app icons and images in assets according to iOS targets and check if warning coming. then build and run the app And if stay remains please review
