Question

I am creating a map application similar to the iphone map app. I need to have the page curl feature, same as that in the map app. Need help in this case.

Answer 1

I think you’ll find that it’s actually quite easy for a partial page curl:

As stated in previous answers to similar questions, you simply need to present a modal view controller with UIModalTransitionStylePartialCurl :

When the view controller is presented, one corner of the current view
curls up to reveal the modal view underneath. On dismissal, the curled
up page unfurls itself back on top of the modal view. A modal view
presented using this transition is itself prevented from presenting
any additional modal views.

This transition style is supported only if the parent view controller
is presenting a full-screen view and you use the
UIModalPresentationFullScreen modal presentation style. Attempting to
use a different form factor for the parent view or a different
presentation style triggers an exception.
