iPad Screen Orientation

Hello,

I have a problem with iOS. My project is build on Unity 4.0.

In fact, when I export my project on iPad3 (iOS 7.0.6) with XCode, I have no problem.
But, if I export the same project on iPadAir or Mini (iOS 8.1) my project is rotated to 90°. I think that iPadAir/Mini sees landscape to portrait mode … My project is lock in landscape mode (Player settings)

I specific that splash screen, when I launch my application on iPad, is in correct orientation. (Splash screen setted in player settings)

If I force my screen to landscape, my GUI is deformed to be size of screen.
If I upgrade my project on Unity 4.5, my problem disapear. But I can’t upgrade my project ! Because the resources, for build they asset bundle, are lost by my society (a lot of resource …). So I need alternative solution for resolve my bug !

My problem come from iOS version, or iPad hardware ? (I’m afraid to update my ios version on iPad 3 …)

What are my solution ?

I am ready to specify differents informations that you need for help me. Just ask me !

If you have a solution, I would be very grateful … !
In waiting for your reply,
Kind regards.

you may want to check out the patches for unity on their own site. i know me and bunch of other people had the same problem but could be fixed with the proper patch. (i dont know if they have anything regarding to this issue in unity 4.0 patches.)

i had the same problem with 4.3 and i end up upgrading the unity itself.

Where I can find this type of patch ? It’s for that I try to target specifically my problem come from. I need information for target my research.

I not found an another people that talking to the same subject …
On Internet, I found a lot of iPadAir orientation problem, but nothing to do. (Some people talk about a landscape lock …)

Perhaps I must download again Unity 4.0 for get the last fixes … I will try …
