I have a file with some metadata prepended to a pdf.I want to strip the metadata off and display the pdf. I was trying to do this: - (void) loadFromPath: (NSString *) path { NSData *myData = [NSData dataWithContentsOfFile:path]; NSString *myStr = [[NSString alloc] initWithData:pdfData encoding:NSASCIIStringEncoding]; // I strip off the metadata here, leaving the pdfStr. // Nothing I've tried here has worked: NSData * myNewData = [pdfStr dataUsingEncoding: ???]; // Display the pdf here... } How can I get this to work?
You can't treat a PDF file as a string, it isn't. You must use NSData methods to work with the raw bytes of the PDF to do the stripping of the metadata instead.
Then you would do something like: PDFDocument* myPDF=[[PDFDocument alloc] initWithData:pdfData]; You can then display the PDFDocument in a PDFView. -- Rob Keniger _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
