- (NSMutableData*)createPDFfromUIScrollView:(UIScrollView*)scrollView{ NSMutableData *pdfData = [NSMutableData data]; UIGraphicsBeginPDFContextToData(pdfData, (CGRect){0,0, scrollView.contentSize}, nil); UIGraphicsBeginPDFPageWithInfo(CGRectMake(0, 0, scrollView.contentSize.width,scrollView.contentSize.height), nil); CGContextRef pdfContext = UIGraphicsGetCurrentContext(); CGRect origSize = scrollView.frame; CGRect newSize = origSize; newSize.size = scrollView.contentSize; [scrollView setFrame:newSize]; [scrollView.layer renderInContext:pdfContext]; [scrollView setFrame:origSize]; UIGraphicsEndPDFContext(); return pdfData; } |
