Hi,
I really need help. I just installed iOS 8. Trying our last game. Screen orientation is set to Landscape Right in Unity but on device it changed on Portrait. With previous verison of iOS it was ok.
Please try it on Unity 4.5.4p1 patch release : Unity Patch Releases - Industries - News & General Discussion - Unity Discussions
Any chance we will see a patch for Unity 3.5 as we did with the non-public API issue that occurred a couple weeks ago?
We are done with our game and want to get it submitted and this just came up. 
You could build & submit your game with Xcode 5.1, this will switch UIKit to old orientation handling model. But then you loose native resolution support for iPhone 6/iPhone 6+.
Yes, the solution was to reinstall the iOS7 SDK and build against that. Unfortunately this will only be viable until February 2015 when Apple will require devs to submit apps built with the iOS8 SDK. So it go.
Issue is still present in Unity 4.5.5f4. Maybe steps little bit different.
