addObjectToUpdateQueue function the interrupt

I think there should be a logical judgment

- (void) addObjectToUpdateQueue:(YPObject *)pdfObject
{
    //add to update array

    [updateObjectQueue addObject:pdfObject];     //Here the interrupt

    //[pdfObject getUncompressedStreamContents];
}

I don't know what you mean. But a pull-request is welcome. This might clarify your suggestion

If the PDF file format simple enough, in this place will cause the interruption of the program, because the judge is not doing enough. The annex to the test file problems.
