Problem with iOS 7 iPad Orientation when view moves up after keyboard appears on UITextField

Question

In my application, I will not move / animate the ViewController view up after the keyboard appears above the UITextField.

and this should support all orientation.
i.e .: UIInterfaceOrientationPortrait
UIInterfaceOrientationPortraitUpsideDown
UIInterfaceOrientationLandscapeLeft
UIInterfaceOrientationLandscapeRight.

For UIInterfaceOrientationPortrait, my code works fine, as shown below:

But for UIInterfaceOrientationPortraitUpsideDown and UIInterfaceOrientationLandscapeLeft it does not work . see below screenshots:

UIView :

static const CGFloat KEYBOARD_ANIMATION_DURATION = 0.3;
static const CGFloat MINIMUM_SCROLL_FRACTION = 0.2;
static const CGFloat MAXIMUM_SCROLL_FRACTION = 0.8;
static const CGFloat PORTRAIT_KEYBOARD_HEIGHT = 264;
static const CGFloat LANDSCAPE_KEYBOARD_HEIGHT = 352;

    -(void) textFieldDidBeginEditing:(UITextField *)textField
    {
        CGRect textFieldRect = [self.view.window convertRect:textField.bounds fromView:textField];

        CGRect viewRect = [self.view.window convertRect:self.view.bounds fromView:self.view];

        CGFloat midline = textFieldRect.origin.y + 0.5 * textFieldRect.size.height;

        CGFloat numerator = midline - viewRect.origin.y - MINIMUM_SCROLL_FRACTION * viewRect.size.height;
        CGFloat denominator = (MAXIMUM_SCROLL_FRACTION - MINIMUM_SCROLL_FRACTION) * viewRect.size.height;
        CGFloat heightFraction = numerator / denominator;

        if (heightFraction < 0.0)
        {
            heightFraction = 0.0;
        }
        else if (heightFraction > 1.0)
        {
            heightFraction = 1.0;
        }

        UIInterfaceOrientation orientation =
        [[UIApplication sharedApplication] statusBarOrientation];
        if (orientation == UIInterfaceOrientationPortrait ||
            orientation == UIInterfaceOrientationPortraitUpsideDown)
        {
            animatedDistance = floor(PORTRAIT_KEYBOARD_HEIGHT * heightFraction);
        }
        else
        {
            animatedDistance = floor(LANDSCAPE_KEYBOARD_HEIGHT * heightFraction);
        }

        if(self.view.frame.origin.y != 0.000000)
        {
            self.view.frame = CGRectMake(self.view.frame.origin.x,0.0,self.view.frame.size.width,self.view.frame.size.height);
        }

        CGRect viewFrame = self.view.frame;
        viewFrame.origin.y -= animatedDistance;

        NSLog(@"View frame y pos did start: %f ",animatedDistance);

        [UIView beginAnimations:nil context:NULL];
        [UIView setAnimationBeginsFromCurrentState:YES];
        [UIView setAnimationDuration:KEYBOARD_ANIMATION_DURATION];

        [self.view setFrame:viewFrame];

        [UIView commitAnimations];
    }

    -(void) textFieldDidEndEditing:(UITextField *)textField
    {
        CGRect viewFrame = self.view.frame;
        viewFrame.origin.y += animatedDistance;

        NSLog(@"View frame y pos did end: %f ",animatedDistance);

        [UIView beginAnimations:nil context:NULL];
        [UIView setAnimationBeginsFromCurrentState:YES];
        [UIView setAnimationDuration:KEYBOARD_ANIMATION_DURATION];

        [UIView commitAnimations];
    }
