I am trying to make a simple iPhone game and I need the game to be in landscape mode. I can get the initial view to be landscape, but if remove the initial view and replace it with a new view (going from Main Menu to Game Screen) the new view is now in portrait mode. Also, if I switchback to the first view (removing the game screen and then creating the new menu view) the view is still in portrait mode. I have the Info.plist file set up correctly to initialize with landscape right and I have the GameViewController.m file set up with the following code: 

-(BOOL) shouldAutorotateToInterfaceOrientation:
        (UIInterfaceOrientation)interfaceOrientation 
{
    return (interfaceOrientation == UIInterfaceOrientationLandscapeRight);
}

I have read many postings about people having troubles with setting up the landscape orientation, but they always seem to be about the initial load of the app (only displaying one view). I can't seem to find any solutions for this problem. Can someone help me?

  • Do both your views have shouldAutorotateToInterfaceOrientation: setup to return YES for UIInterfaceOrientationLandscapeRight ? – Tudor Apr 10 '11 at 17:40

Make sure that all the view controllers that are visible on screen support the landscape orientation. I would recommend, in your shouldAutorotateToInterfaceOrientation, to return UIInterfaceOrientationIsIsLandscape(interfaceOrientation); instead of your code. This will ensure that both landscape orientation will work. Can you share a bit more how you are switching from the main menu to the game screen?

  • This function gets called when i touch the screen and after two touches, it changes to the next view. -(void) touchesEnded:(NSSet*)touches withEvent:(UIEvent*)event { UITouch* touch = [touches anyObject]; NSUInteger numTaps = [touch tapCount]; if(numTaps > 1) { [m_pManager doStateChange:[gsMain class]]; } } – usherjer Apr 10 '11 at 20:03
