I have a UIView subclass which displays a PDF, and this is embedded in a UIScrollView. When the user zooms in, the PDF content is pixelated. I've double checked, and anti-aliasing is enabled. If I display the PDF at a larger size using CGContextScaleCTM, it displays fine, but I don't know how to integrate this with the UIScrollView zooming. Is this possible, or should I eliminate the UIScrollView and handle the scrolling and zooming myself?
