Hi all
I have made a application to show a PDF document, I follow an internet
examples but the app crashes after few milliseconds after shown the
document.
Below the source code:
NSUrl ns = NSUrl.FromFilename(s);
UIDocumentInteractionController PreviewController =
UIDocumentInteractionController.FromUrl(ns);
PreviewController.Delegate = new
MxUIDocumentInteractionControllerDelegateClass(MxSession.LoadedViewsCollection[MxViewType.ProductDetails].Instance);
PreviewController.PresentPreview(false);
public class MxUIDocumentInteractionControllerDelegateClass :
UIDocumentInteractionControllerDelegate
{
private UIViewController mViewController;
//private DTSVirtualFile mFile;
public MxUIDocumentInteractionControllerDelegateClass(UIViewController
viewController)
{
mViewController = viewController;
//mFile = file;
}
public override UIViewController ViewControllerForPreview
(UIDocumentInteractionController controller)
{
return mViewController;
}
public override UIView ViewForPreview (UIDocumentInteractionController
controller)
{
return mViewController.View;
}
public override RectangleF RectangleForPreview
(UIDocumentInteractionController controller)
{
return mViewController.View.Frame;
}
public override void DidEndPreview (UIDocumentInteractionController
controller)
{
Console.WriteLine ("WillBeginPreview");
}
public override void DidDismissOptionsMenu
(UIDocumentInteractionController controller)
{
// TODO: Implement - see:
http://go-mono.com/docs/index.aspx?link=T%3aMonoTouch.Foundation.ModelAttribute
}
public override void WillBeginPreview (UIDocumentInteractionController
controller)
{
Console.WriteLine("WillBeginPreview");
}
public override void WillBeginSendingToApplication
(UIDocumentInteractionController controller)
{
// TODO: Implement - see:
http://go-mono.com/docs/index.aspx?link=T%3aMonoTouch.Foundation.ModelAttribute
}
public override void WillPresentOpenInMenu
(UIDocumentInteractionController controller)
{
// TODO: Implement - see:
http://go-mono.com/docs/index.aspx?link=T%3aMonoTouch.Foundation.ModelAttribute
}
public override void WillPresentOptionsMenu
(UIDocumentInteractionController controller)
{
// TODO: Implement - see:
http://go-mono.com/docs/index.aspx?link=T%3aMonoTouch.Foundation.ModelAttribute
}
}

How can I solve this problem? or is there a workaround?
