The UIDocumentInteractionController
appears to be non-functional in iPad Simulator ("iPhone Simulator" version 4.0, shipping with XCode 3.2.3, using iOS Version 3.2).
I have a simple sample code presenting a PDF preview using UIDocumentInteractionController. It works on the device. On iPad presentPreview just returns NO, the UIDocumentInteractionController's delegate methods are not invoked.
Any hint how to make it work?
