How do I fullscreen in iPhone without navigation bar

Hi, I'm new, I'm trying to fullscreen my game in the cell, but the navigation bar is ever present, I want to see only the game in the screen of the cell.

a second question is how I do to permanently see the game in horizontal regardless of the orientation.

sorry if the questions are useless and very thanks to all who can help me.

iOS doesn't currently support fullscreen or orientation lock in Safari. The best you can do is 'add to home screen' which makes it fullscreen when run from the home screen, but still not orientation locked.
