How iPhone 5 + iOS6 will decide if an app must be run in letterbox mode

Question

How the iOS6 decides if the app must be run in letterbox/compatibility mode on iPhone 5? Is this a build settings parameter (like the \"Targeted device family\")? Or all app

Answer 1

You will need to add IOS8 specific splash screen too. In my case i had 1136x640 Default.png splashscreen but you need to select launch screen and select orientation as shown below

This worked for me. Hope this helps :)
