Sample code

Attached sample does not appear to work (I've ported some Objective-C from http://nshipster.com/ios7/)

The following line of C# (which seems like it should work) causes a crash

    output.MetadataObjectTypes = new NSString[] {AVMetadataObject.TypeQRCode};


Also, output.AvailableMetadataObjectTypes is empty (zero entries).

Thanks!

p.s. I'm testing on an iPad mini with iOS7 installed.

You need to add the output to the session first:

session.AddOutput (output);

then AvailableMetadataObjectTypes returns a bunch of types (and setting MetadataObjectTypes doesn't crash).
