First UIView in Portrait orientation and second in Landscape

Question

I have an app which has 2 view controllers. The first viewcontroller should be in portrait and it's ok, but when I'm loading the second view controller, I could not make the app orientation to be landscape... The problem is with iOS 6.

I have tried everything I found on SO.

Using [[UIApplication sharedApplication] setStatusBarOrientation:UIInterfaceOrientationLandscapeRight animated:NO]; on viewWillAppear and viewDidLoad,

and also:

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

 -(BOOL)shouldAutorotate
  {
return YES;
  }

- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation
 {
return UIInterfaceOrientationLandscapeRight;
 }

-(NSInteger)supportedInterfaceOrientations{

return UIInterfaceOrientationMaskLandscapeRight;
}

Answer 1

Add these code in 2nd View Controller's viewDidLoad method to transform view into landscape :

[self rotateController:self degrees:-90];
[[UIApplication sharedApplication] setStatusBarOrientation:UIInterfaceOrientationLandscapeLeft animated:NO];
//set it according to 3.5 and 4.0 inch screen in landscape mode
[self.view setBounds:CGRectMake(0, 0, 480, 320)]; 

add rotateController method :

 -(void) rotateController:(UIViewController *)controller degrees:(NSInteger)aDgrees
{
  UIScreen *screen = [UIScreen mainScreen];
  if(aDgrees>0)
    controller.view.bounds = CGRectMake(0, 0, screen.bounds.size.height, screen.bounds.size.width);
  else
  {
    controller.view.bounds = CGRectMake(0, 0, screen.bounds.size.width, screen.bounds.size.height);
  }
  controller.view.transform = CGAffineTransformConcat(controller.view.transform, CGAffineTransformMakeRotation(DEGREES_TO_RADIANS(aDgrees)));
}

Now in viewWillDisappear's method to transform view into protrait . Add these:

[self rotateController:self degrees:90];
[[UIApplication sharedApplication] setStatusBarOrientation:UIInterfaceOrientationPortrait animated:NO];
//set it according to 3.5 and 4.0 inch screen in protrait mode
[self.view setBounds:CGRectMake(0, 0, 320, 480)];

Also your orientation methods should be like these if not added add these :

- (BOOL)shouldAutorotate
{    
  //make view landscape on start
  return NO;
}

- (NSUInteger)supportedInterfaceOrientations
{
  return UIInterfaceOrientationMaskLandscapeLeft;
}

- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation
{
  return UIInterfaceOrientationLandscapeLeft;
}

EDIT : Add these macro for radian

#define DEGREES_TO_RADIANS(angle) ((angle) / 180.0 * M_PI)
