Only having one view autorotate in xcode?

Question

Ok so I currently have 3 views and I need only one of them to autorotate to any orientation while the rest stay in portrait. Right now my set up is a splashviewcontroller fades into view A, and inside view A is a button to switch to view B. All I want is for view B to be able to rotate to any orientation.

When I return YES for shouldautorotatetointerfaceorientation in the splashviewcontroller, every view rotates because this is the parent view. When I return portrait only in the splashview, nothing rotates even if the other views return YES. Is there a way to only have view B rotate? I'm willing to do it manually if you can provide code. Thanks

You can manually mange the rotation of any desired UIView object like so:

EDIT:

In the init or viewDidLoad

- (void)viewDidLoad
{
    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(rotate) name:UIDeviceOrientationDidChangeNotification object:nil];

    [super viewDidLoad];
}

#define degreesToRadian(x) (M_PI * (x) / 180.0)

-(void)rotate{

    self.view.bounds = CGRectMake(0, 0, 0, 0);

    if ([UIDevice currentDevice].orientation == UIInterfaceOrientationPortrait){


        CGAffineTransform landscapeTransform = CGAffineTransformMakeRotation(degreesToRadian(0));
        landscapeTransform = CGAffineTransformTranslate (landscapeTransform, 0.0, 0.0);

        self.view.bounds = CGRectMake(self.view.bounds.origin.x, self.view.bounds.origin.y, 320, 480);

        [self.view setTransform:landscapeTransform];


    } else if ([UIDevice currentDevice].orientation == UIInterfaceOrientationPortraitUpsideDown){


        CGAffineTransform landscapeTransform = CGAffineTransformMakeRotation(degreesToRadian(180));
        landscapeTransform = CGAffineTransformTranslate (landscapeTransform, 0.0, 0.0);

        self.view.bounds = CGRectMake(self.view.bounds.origin.x, self.view.bounds.origin.y, 320, 480);

        [self.view setTransform:landscapeTransform];

    } else if ([UIDevice currentDevice].orientation == UIInterfaceOrientationLandscapeRight){

        CGAffineTransform landscapeTransform = CGAffineTransformMakeRotation(degreesToRadian(90));

         landscapeTransform = CGAffineTransformTranslate (landscapeTransform, 0.0, 0.0);
         self.view.bounds = CGRectMake(self.view.bounds.origin.x, self.view.bounds.origin.y, 480, 320); 


        [self.view setTransform:landscapeTransform];

    }else if ([UIDevice currentDevice].orientation == UIInterfaceOrientationLandscapeLeft){

        CGAffineTransform landscapeTransform = CGAffineTransformMakeRotation(degreesToRadian(270));

        landscapeTransform = CGAffineTransformTranslate (landscapeTransform, 0.0, 0.0);
        self.view.bounds = CGRectMake(self.view.bounds.origin.x, self.view.bounds.origin.y, 480, 320); 

        [self.view setTransform:landscapeTransform];
    }

}
