How to set Orientation in Unity to be landscapeLeft?

i’m using unity 4.3.4 and xcode 6.3.2, ios 8.0. i want my game to be landscape left, but no matter how i set the oritation in unity and xcoe, the game seems always not right. So how to set parameters correctly? Does the version of unity matter?

I’m developing for android and using strictly Unity, but I believe the option is in Build Settings-> Player Settings. Have you checked there to set the orientation? I set mine to be only Landscape left and it seems to work fine on my phone.
