Try this:

CGPDFDocumentRef document;
UIGraphicsBeginImageContext(/* PDF_SIZE */);
CGContextRef context = UIGraphicsGetCurrentContext();
CGContextDrawPDFPage(context, CGPDFDocumentGetPage(/* PDF_PAGE */));

UIImage *output = UIGraphicsGetImageFromCurrentImageContext();

UIGraphicsEndImageContext();
