Hi,
If I use this code, everything is fine. I just call
PdfViewerController2.ShowModally(). In there, you see a part that is
commented out. If I use that subclass instead of PSPDFViewController
directly, it fails and I get the exception below.
Can somebody please explain what is going on? The PSPDFViewController is
coming from a bound library.
public class SubclassedController : PSPDFViewController
{
private SubclassedController (PSPDFDocument oDoc) : base(oDoc)
{
}
public static void ShowModally(string sFilename)
{
PSPDFDocument oDoc = new PSPDFDocument(NSUrl.FromFilename(sFilename));
// This is working.
var oController = new PSPDFViewController(oDoc)
{
ModalPresentationStyle =
MonoTouch.UIKit.UIModalPresentationStyle.FullScreen,
ModalTransitionStyle = MonoTouch.UIKit.UIModalTransitionStyle.CoverVertical
} ;
// This isn't!
/*var oController = new SubclassedController(oDoc)
{
ModalPresentationStyle =
MonoTouch.UIKit.UIModalPresentationStyle.FullScreen,
ModalTransitionStyle = MonoTouch.UIKit.UIModalTransitionStyle.CoverVertical
} ;*/
AppDelegateBase.BaseAppDelegate.MainController.PresentViewController(oController,
true, delegate {} );
}
}
