I'm fairly certain this is a bug, but in case anyone has found a way around this, let me know.
I've set up an asset catalog in Xcode-5 of launch images. If I set an iOS 7 R4 image it is only used if my app supports portrait orientation. My app is landscape-right only and I do not see the launch image.
The iOS 5,6 images work just fine, and the R4 iOS 5,6 image will actually load "correctly" if I leave out the iOS 7 R4 image.
Has anyone been able to get this to work?
Update
I've found that I can get iOS 7 landscape images to appear, but only if I remove the default (iOS6) images, which doesn't really help me. If you edit the info.plist and change the image orientation to "Landscape (right home button)" (for example), then provide a horizontal image, it will actually show it on iOS 7 at launch. Unfortunately, if you include an iOS 6 image, it shows that instead. Also, you will not see the iOS 7 image listed in the "General" tab of your target if the orientation is anything other than Portrait. This is with Xcode 5.0 and iOS 7.0.2.
