In your UIViewController write something like this (example below is to force 
the app into landscape mode only):

// Override to allow orientations other than the default portrait orientation.
- 
(BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
 {
    // Return YES for supported orientations
        
        if (interfaceOrientation == UIInterfaceOrientationLandscapeLeft) {
                [[UIApplication sharedApplication] 
setStatusBarOrientation:UIInterfaceOrientationLandscapeLeft];
                return YES;
        } else if (interfaceOrientation == 
UIInterfaceOrientationLandscapeRight) {
                [[UIApplication sharedApplication] 
setStatusBarOrientation:UIInterfaceOrientationLandscapeRight];
                return YES;
        }
    
        return NO;
}
