An iPad app can support inclusion of launch images in both orientations; presumably, if your app supports auto-rotation, then this would suggest to me that if the user launches an app while the device is in Landscape mode, then the Landscape launch image is used.
But in all the apps I've built and released, this has never been the case. Never once has the Landscape launch image appeared, only the Portrait. After loading, the app will auto-rotate to whatever orientation the device is in, but at launch, it assumes you are in Portrait. Always.
Why?
I have seen many other apps in the store that behave this way, but then there are some seem to always automatically know immediately at first launch, from that first launch image, that you are in Landscape, if that's the case.
How is this done?
iPhone supports only portrait images (http://developer.apple.com/library/ios/#documentation/userexperience/conceptual/mobilehig/IconsImages/IconsImages.html#//apple_ref/doc/uid/TP40006556-CH14-SW5)
Apps that don't support portrait orientations, provide the same portrait oriented image. For example, Angry birds on iPhone has the same portrait oriented image but the guys painted rotated graphics on it.
As it would turn out, the issue was due to leaving out the supported orientations in the plist file for the app. You can add these manually or just select them in the Target page. More details here:

I'm developing universal app (game) which working only in landscape modes. Can I do not specify Launch images for portrait mode for saving size?
Yes, adding "Default-Landscape.png" will be enough, if you need so.
"Universal apps must provide launch images for both the iPhone and iPad idioms".. BUT.. launch images for the iPhone are only accepted in portrait mode (link).
so.. for Default.png or Default-iphone.png .. to provide a landscape launch image you must create the image and rotate it 90 degrees in an image editor
i am developing an app which supports all orientations. i need to launch the splash screen (launching image) in all orientation types. but the project summary have only one field (portrait) to set the Default.png. how will i launch the landscape splash screen on my iphone app.
ipad have some features to setup both the orientations. is their anything like that in iphone,
thank you in advance
iPhone splash screen is only Portrait. iPad has landscape too because iPad home screen auto rotates unlike iPhone's.
In order to achieve such a behavior you can make your first screen identical to the splash screen ( add the same image on the background) . So it will look like a landscaped splash screen while you are loading the resources needed for your app but you can't start the app in landscape mode.
Hope this helps.
Cheers!
Nope, according to HIG, iPhone's default orientation is portrait and launch will do only portrait mode.
Let me quote a special behaviour
From Technical Note TN2244 Launching your iPhone Application in Landscape
Except for launch images used by the iPhone 6 Plus, asset catalogs assume that all iPhone launch images are for the portrait orientation.
Therefore
Launch images for iPhone apps are always sized to match the dimensions of the screen in portrait orientation. For applications that launch into landscape orientation, you should use your preferred graphics editing software to rotate the content of the launch image while keeping the image's size consistent with a portrait launch image (height > width).
if you don't do things correctly, you can end up with a blank/white screen
The result is a blank screen during launch as the system cannot find an appropriate launch image.
Unfortunately, the document was last updated 2 years ago.

How to change a launching image to landscape?
I want to set different launching image when device was landscape mode.
so, I made a PNG file (file name : default-LandscapeLeft#2x~iphone.png)
and dragged it in supporting files folder.
and then building and running in device landscape mode.
but I have seen only black screen.
I can't know reason..
I doubt if .plist file was needed to modify..
Please help from advanced guy....
If you are on an iPhone or iPod, and if your app supports both portrait and landscape mode, then iOS always launches it in portrait mode. After it is launched, if the device is in landscape mode, then iOS tells your app to autorotate to landscape mode. This is explained in iOS App Programming Guide: Launching in Landscape Mode.
I am developing one iphone app, and i want to support all orientations.
The problem is that I want the default.png to be launched in the proper way according to the orientation at start up. Can someone post some method or proper name for default images so that I can rotate it?
Basically there is a landscape "default" image only for iPad. in iPhone you should suplly only one in the main orientation of your app.
anyway, if you want to do that, there is a workaround posted in this question:
Auto-rotate the default application image according to current landscape mode
I am developing an application that is in landscape mode. I have Default.png with size 480x320.
But still when it launches the default image comes in portrait mode not in landscape mode.
However it should come according to the device oreintation.
If i take default.png with same size in allready rotated. then it comes as it was in rotated mode.
However it should come according to the device oreintation.
Please help me
There is an answer to question How to put Default.png in landscape mode? by #brentford that should help you.
There is also an article by John Muchow which outlines a different way one way to accomplish what you want to do.
Taken straight from here
"In iOS 3.2 and later, an iPad application can provide different launch images depending on whether the device is in a portrait or landscape configuration. To specify a launch image for a different orientation, you must add a special modifier string to the base file name of your standard launch image. Thus, the format of each file name becomes the following:
[basename][orientation_modifier][scale_modifier][device_modifier].png"
So in your example you could have:
Default-Landscape.png
Default-Portrait.png
(Default-Landscape#2x.png for iphone 4 and Default-Landscape~ipad.png for ipad and so forth...)
both have to be 320x480 and you'll have to ensure that your app's Info.plist contains all 4 UISupportedOrientation values (UIOrientationPortrait, UIOrientationLandscapeLeft etc etc). But see my above link for a better explanation.
I believe the splashscreen is loaded without checking for orientation.
Try to set UIInterfaceOrientation key in the info.plist file to UIInterfaceOrientationLandscapeLeft (iPhone home button will be on the left) or UIInterfaceOrientationLandscapeRight (home button on right).
