Hi Marco, Can it be that pieceInfo is NULL? I.e. the GetIndirectKey() returns a NULL object, because the PieceInfo directory is not available in the PDF?
Another thing you could try, is to disable the LoadOnDemand mechanism? Does it
work if you disable it? (Even though, this is obviously no long term solution
on an iPhone)
Cheers,
Dominik
