iPad Partial Curl modal transition always curls to full screen

I'm using UIModalTransitionStylePartialCurl to show a modal view in iPad.

mod开发者_开发百科alViewController.modalTransitionStyle = UIModalTransitionStylePartialCurl;
[[self parentViewController] presentModalViewController:modalViewController animated:YES];

self is the right side view controller of my SplitViewController.

When I do this, the page is curled all the way to the top even though the size of the view of modalViewController is small. I only need it to curl a little so it would reveal ONLY the area taken by modalViewController. What I'm trying to do is something exactly like the iPad maps application settings.

I tried using all the modalPresentationStyle options for the modal view and I also tried setting the modalPresentationStyle.view.frame to a small CGRect but still couldn't get it to work.

Can anybody help on this...thanks in advance..

Just leave a clean space (No Controls or Images) in the top of your PresentedViewController, the Framework make the rest.

I have yet to find a more optimal solution, but I've been able to get good results by making the modal (revealed) view the same size as the parent (curling) view. iOS looks at the subviews to determine where to stop the curling and shows "just enough" of the subview to keep the subview pieces on-screen.
