i'm working on pdf annotations application , need save annotation when tried save annotations , pdf content new pdf , annotations saved content of pdf not ? here function :
-(void)save_doc_as_pdf:(readermaintoolbar *)toolbar backbutton:(uibutton *)button { nserror *error; nsstring *pdfpath = [document.fileurl absolutestring]; nsstring *newpath = [pdfpath stringbyreplacingoccurrencesofstring:@"file://localhost" withstring:@""]; nsstring *newpdfpath = [thenewpath stringbyreplacingoccurrencesofstring:@".pdf" withstring:@"_1.pdf"]; nsdata *pdfdata = [nsdata datawithcontentsoffile:[document.fileurl path] options:nsdatareadinguncached error:&error]; if (pdfdata == nil) { nslog(@"data nil !!!!"); } if (error) { nslog(@"%@", [error localizeddescription]); return; } else nslog(@"data has loaded successfully."); //if fails create new file, returns if (![[nsfilemanager defaultmanager] createfileatpath:newpdfpath contents:pdfdata attributes:nil]) { return; } nsurl *url = [nsurl fileurlwithpath:newpath]; cgpdfdocumentref pdf_document = cgpdfdocumentcreatewithurl ((__bridge_retained cfurlref) url); size_t count = cgpdfdocumentgetnumberofpages(pdf_document); if (count == 0) { nslog(@"pdf needs @ least 1 page"); return; } cgrect papersize = cgrectmake(0, 0,842, 1190); uigraphicsbeginpdfcontexttofile(newpdfpath , papersize, nil); // cgpdfpageref page = cgpdfdocumentgetpage(document, 1); uigraphicsbeginpdfpagewithinfo(papersize, nil); cgcontextref currentcontext = uigraphicsgetcurrentcontext(); // flip context page right way (landscape app) cgcontextscalectm(currentcontext, 1, -1); // rotate coordinate system (rotation = m_pi or -m_pi landscape) //cgcontextrotatectm(currentcontext, rotation/ 2); cgpdfpageref page = cgpdfdocumentgetpage (pdf_document, 1); // grab page 1 of pdf cgcontextdrawpdfpage (currentcontext, page); // draw page 1 graphics context //flip context annotations right way cgcontextscalectm(currentcontext, 1, -1); //cgcontextrotatectm(currentcontext, rotation / 2); //render layer of annotations view in context [startdraw.layer renderincontext:currentcontext]; uigraphicsendpdfcontext(); cgpdfdocumentrelease (pdf_document); }
hello find solution saving annotaion on pdf document , want shar here code :
-(void)save_the_pdf:(readermaintoolbar *)toolbar backbutton:(uibutton *)button{ nsmutablearray *urlstableobject=[[nsmutablearray alloc] init]; nsmutablearray *urlstable=[[nsmutablearray alloc] init]; nsuserdefaults *datastoreurls; nsstring *originalpdfname = [document.filename stringbyreplacingoccurrencesofstring:@".pdf" withstring:@""]; nsstring *originalpdfpath = [document.filename stringbyreplacingoccurrencesofstring:@".pdf" withstring:@""]; nsstring* thenewpath = [[nsbundle mainbundle] pathforresource:originalpdfpath oftype:@"pdf"]; nsstring *newpdfpath = [thenewpath stringbyreplacingoccurrencesofstring:@".pdf" withstring:@"_1.pdf"]; cgpdfdocumentref pdf = cgpdfdocumentcreatewithurl((__bridge cfurlref)[[nsbundle mainbundle] urlforresource:originalpdfname withextension:@"pdf"]); const size_t numberofpages = cgpdfdocumentgetnumberofpages(pdf); nsmutabledata* data = [nsmutabledata data]; uigraphicsbeginpdfcontexttodata(data, cgrectzero, nil); for(size_t page = 1; page <= numberofpages; page++) { // current page , page frame cgpdfpageref pdfpage = cgpdfdocumentgetpage(pdf, page); const cgrect pageframe = cgpdfpagegetboxrect(pdfpage, kcgpdfmediabox); uigraphicsbeginpdfpagewithinfo(pageframe, nil); // draw page (flipped) cgcontextref ctx = uigraphicsgetcurrentcontext(); cgcontextsavegstate(ctx); cgcontextscalectm(ctx, 1, -1); cgcontexttranslatectm(ctx, 0, -pageframe.size.height); cgcontextdrawpdfpage(ctx, pdfpage); cgcontextrestoregstate(ctx); if (page == currentpage) { [startdraw.layer renderincontext:ctx]; } } uigraphicsendpdfcontext(); cgpdfdocumentrelease(pdf); //pdf = nil; if (![[nsfilemanager defaultmanager] createfileatpath:newpdfpath contents:data attributes:nil]) { return; } // 'data'... datastoreurls=[nsuserdefaults standarduserdefaults]; if([datastoreurls objectforkey:@"allurls"]!=null){ urlstableobject=[datastoreurls objectforkey:@"allurls"]; int index=[urlstableobject count]; urlstable=[[nsmutablearray alloc] initwitharray:urlstableobject]; [urlstable insertobject:newpdfpath atindex:index]; [datastoreurls setobject:urlstable forkey:@"allurls"]; }else{ [urlstable addobject:newpdfpath]; [datastoreurls setobject:urlstable forkey:@"allurls"]; } [datastoreurls synchronize]; }
