How do I change landscape orientation?

I can't change orientation of my game. I made a game in 1136;640 resolution for iOs, choose landscape orientation in project properties and in Intel XDK I also choose landscape. But building on adhoc and testing my game on my I phone I see that orientation is not landscape but portrait. What is wrong?
