Is this at all possible without converting the PDF to an image? If not, what are the member functions for converting a PDF into a PNG? I would really prefer to preserve the PDF if at all pssoible.

问题 While attempting to debug a build created using the 3.2 SDK on an iPhone device I receive the message "A signed resource has been added, modified, or deleted.". I can clean, rebuild, then install with no error, but if I try to install without cleaning the error shows.
