要求將PDF拆分爲單個頁面,僅將個別文件保留爲.pdf擴展名。 在/ CreatedPDF文件夾中創建的文件未打開如何通過編程將PDF拆分爲獨立的單頁PDF格式
請幫助確定/糾正此問題。
//"fileURL" is the original File which has to be broken
//"pages" is the number of pages in PDF
NSInteger pages = CGPDFDocumentGetNumberOfPages(pdfDocReference);
for (int page = 1; page <= pages; page++)
{
NSFileManager *fm = [NSFileManager defaultManager];
NSString *dirName = [documentsDirectory stringByAppendingPathComponent:@"/CreatedPDF"];
[fm createDirectoryAtPath:dirName withIntermediateDirectories:YES attributes:nil error:nil];
NSString *pdfPath = [dirName stringByAppendingPathComponent:[NSString stringWithFormat:@"page_%d.pdf",page]];
NSURL *pdfUrl = [NSURL fileURLWithPath:pdfPath];
CGContextRef context = CGPDFContextCreateWithURL((__bridge_retained CFURLRef)pdfUrl, NULL, NULL);
CGPDFDocumentRef pdfDoc = CGPDFDocumentCreateWithURL((__bridge_retained CFURLRef)fileURL);
CGPDFPageRef pdfPage = CGPDFDocumentGetPage(pdfDoc, 1);
CGRect pdfCropBoxRect = CGPDFPageGetBoxRect(pdfPage, kCGPDFMediaBox);
// Copy the page to the new document
CGContextBeginPage(context, &pdfCropBoxRect);
CGContextDrawPDFPage(context, pdfPage);
// Close the source files
CGContextEndPage(context);
CGPDFDocumentRelease(pdfDoc);
}
您可以添加完整的代碼來從PDF中提取頁面嗎?這對未來的讀者會有所幫助。 – Hemang 2017-05-04 12:25:18
