A very simple App is created to deal with pdf file providing open/save/highlight pdf file utilizing PDFKit.
pdfDoc is used to load pdf file:
pdfDoc = [PDFDocument alloc];
pdfDoc = [pdfDoc initWithURL:url];
the following code is used to save changed pdf file:
[pdfDoc writeToFile:path];
The App can save a pdf file changed by highlight some texts and reopen it properly. But if the
Chinese/Japanese/Korea (CJK) text of the reopened pdf file is selected and copied, the text pasted
is error codes.
I do not know whether I miss something in the codes or it is a bug in PDFKit. It seems Preview.app has the
same problem before, but it works fine now.
Any suggestion for solving the problem will be appreciated.
