Unable to save pdf form data using PDFKit iOS 11

Question

I have loaded a pdf form using PDFKit in iOS 11. I am trying to save the editable fields ( Checkbox, TextBox) values. How do I get back the editable PDFDocument object to save the PDF contents using

• (BOOL)writeToFile:(NSString *)path;

Answer 1

Thanks. I did something like this. I added and Observer and on receiving notification when the pdf changes write the contents to a filepath

PDFView *view = notification.object;
PDFDocument *myDocument = view.document;
NSData* content = myDocument.dataRepresentation; 
[content writeToFile:newPath atomically:YES];

That worked for me.
