Landscape-mode page curl issue in iPhone app

Question

In my app, I have a page curl effect. The page curl effect works correctly in portrait mode whereas in landscape mode the page curl ending takes place at the corner of the i pad.

In landscape mode I want the page to be get separated in the middle as in the following figure.

But my page curl effects looks as the following figure.

I am using the following code:

-(void)PresentView
{
    [UIView animateWithDuration:1.0  animations:^
    {
                         CATransition *animation = [CATransition animation];

                         [animation setDelegate:self];
                         [animation setDuration:0.7];

                         [animation setTimingFunction:UIViewAnimationCurveEaseInOut];

                         animation.type = @"pageCurl";

                         animation.fillMode = kCAFillModeForwards;
                         animation.endProgress = 0.65;

                         [animation setRemovedOnCompletion:NO];
                         [m_container.layer addAnimation:animation forKey:@"pageCurlAnimation"];  

                         [m_container addSubview:self];
                         ;}  

     ];    
}

How do I get the page curl animation in landscape mode as in the first figure?

You need to adjust two properties of UIPageViewController:

• Set doubleSided to YES, so that each page has content on both of its sides
• Set spineLocation to UIPageViewControllerSpineLocationMid so that you have two pages joined in the middle of view
