How to deal with iPhone 5 screen size?
How can I add support for 4-inch iPhone 5 displays to an iOS app in Xcode?
Is this even possible with the latest public Xcode release, v4.4.1?
回答1:
Add a new launch image named Default-568h@2x.png to your project and it will work!
回答2:
If your application is iOS6 only, the easiest way to make views that layout correctly in both 3.5-inch and 4-inch iPhone 5 designs is to use AutoLayout in your XIBs to make them adapt their size automatically (See the WWDC'2012 video sessions about that). If your application must support versions prior to iOS6, then you can still use AutoResizingMasks on your views to make them resize themselves to adapt to both 3.5 and 4 inch screens.
Then for your application to support the 4-inch display and take the whole screen when launched on an iPhone 5, simply add a "Default-568h@2x.png" launch image to your project.
The simple presence of this launch image will make your application launch full-screen on iPhone 5 instead of having black bands at the top and bottom.

Short answer : use the new launch image slot ( the Retina 4-inch ) one in XCode->Targets->Summary->iPhone/iPod Deployment Info
I have an OpenGL ES 2 app that despite all options I checked, nothing worked. Creating a new GLGame project adds black launch images for Retina 3.5 inch and Retina 4 inch. Despite every other comparison to project settings or .plist file I found nothing else to say "make it available for iPhone 5". I sure hope this changes in the future.
