Question

I am using the UIDocumentInteractionController to preview pdf files. I display the controller as follows:

self.docInteractionController = [UIDocumentInteractionController interactionControllerWithURL:pdfUrl];
    self.docInteractionController.delegate = self;
    self.docInteractionController.name = literature.title;
    [self.docInteractionController presentPreviewAnimated:YES];  

It all works a treat. However, if I add an Exception Breakpoint catch-all to Xcode and debug the app then I notice quite a few crashes happening as I interact with the pdf document. The app does not crash totally, but the exception breakpoint fires whenever I tap on the document.

Do I need to worry about this behaviour?

Was it helpful?

Solution

If you are not retaining the UIDocumentInteractionController Object thats when you will see a crash. Try to retain self.docInteractionController. I too ran into the same problem and this fixed it.
