Description Allie Miller 2014-05-21 16:02:00 UTC
When a user opens a PDF file using the Quick Look Previewer in a Xamarin.iOS application on an iPad, the document fails to load (grey screen appears) with the text:

<pdf filename>
my pdf viewer
<file size>

This only occurs when the third-party app ClickMeeting is also installed on the device.

To reproduce the issue:
1) Download the attached test project PDFViewerTest
2) Install the ClickMeeting application on the iPad.
3) Attempt to deploy the PDFViewerTest to the iPad device

Expected
The pdf should appear whether the ClickMeeting app is installed or not.

Results
The pdf fails to load

Comment 2 Rolf Bjarne Kvinge [MSFT] 2014-05-22 04:40:05 UTC
It's because ClickMeeting handles pdfs by setting CFBundleDocumentTypes/UTExportedTypeDeclarations in their Info.plist.

There is nothing Xamarin can do about this.

It might be possible to 'override' ClickMeeting by setting the same options in the app's Info.plist.
