Symptoms
- Calling the screen orientation changes from portrait to landscape mode, even if the project is set to use portrait mode only
Cause
If you are using the iOS presentation controller, this could override your orientation constraints.
Resolution
As a workaround, you can modify the iOS trampoline code to use only the portrait mode.
Build for iOS and open UnityAppController.mm and replace supportedInterfaceOrientationsForWindow with the provided code:
- (NSUInteger)application:(UIApplication*)application supportedInterfaceOrientationsForWindow:(UIWindow*)window
{
return (1 << UIInterfaceOrientationPortrait) |
(0 << UIInterfaceOrientationPortraitUpsideDown) |
(0 << UIInterfaceOrientationLandscapeRight) |
(0 << UIInterfaceOrientationLandscapeLeft);
}

Worked for me using Unity 5.3.3f1. Really thank a lot for this Answer :)
Works for me in Unity 5.3.5f1.
You can leave out the last 3 lines. They're just like doing 4 + 0 + 0 + 0 (so you can leave out the zeroes and still have the 4 left).
is enough.
Be careful of using this as a solution for landscape games not to turn portrait, though: it could end up crashing smaller iPhones when you hold the device in portrait mode and open Game Center. So test that ;)
