How can I change the orientation of the build in Unity SplashScreen in iOS(Free), my game is in Landscape orientation but the SplashScreen is always in Portrait orientation and I would like to have both the same orientation.
Do not manipulate the Unity SplashScreen by hand, your app stops working immediately!!
Check this question, and see if it helps.
It may be a little too late, but running 3.5.6 fixed this issue.
Create a new Xcode project, with a diffrent name than the orginal one, pass your Unitybuild to it and the problem is gone!
At least this was the working solution for me.(Note that I have checked the orientation of the images in Unity and Xcode more than once, they were all correct)
Then, 4.6.0 users may need to wait for a patch release or 4.6.1, as current 4.6.0 does not include the changes from 3.5.5f1 to 3.5.6.
