I have developed a pdf reader using schwa/iOS-PDF-Reader API. I am experiencing a caching problem, I supply my file path dynamically to the API, but the reader always brings up the first pdf file irrespective of the file path supplied.
Please help me out..
Thanks in advance...
You can give all pdf paths into an array and then just pass array index path to your API.
Just try it i hope it will help for you.

I'm using jQuery fileupload on a site to upload a single file for processing. I've got a simple upload working based on the Basic Plus demo, but would like to upload files to a given path and filename on the server (independent of the filename on the client machine). It seems like this should be straightforward, but I'm having problems figuring it out or finding resources. Is this possible in jQuery fileupload? If so, can anybody point me in the right direction for how?
Thanks for your time!
Answered? Found some helpful information here on changing the filename of uploads.
hi im working on pdf manipulation.
my requirements are to edit the existing pdf document.
looks like there is no actual way to do it. i found out using javascript i can edit the html contents.
so now that my pdf is in uiwebview is there any way to convert pdf document to html content???
i have to do it programatically.
preferred language is objective c but its k if any suggestions in C/C++
thanks in advance
You will have to drop down to C if you want to do this. Basically you need to get hold of a CGPDFDocumentRef reference, and through that iterate each CGPDFPageRef. From the page you can get access to the CGPDFContentStreamRef.
From the content stream you can parse out the primitive data that is is PDF document. From there only a good understanding of the PDF document format can help you.
I would advice you to find a commercial tool, hire an experience contractor, or change your plan. What you have your sights on is allot of hard work.
I'm receiving a pdf that contains some data I would like to parse.
For example, there's an array with some integer data that I would like to parse for an automatic treatment.
I've looked at itext but the sample I've found are for writing pdf only.
Can someone give me an example of how to read through a pdf ?
Thanks in advance for any help.
Best regards
PdfBox is much better for reading text from a PDF file.
Finally,
I'm converting PDF to Word and I'm using Word interop :)
How can I scan links in a PDF Document? Do I have to use Quartz? Which methods/functions?
Yes, you need to use Quartz. You have to parse it out from the PDF. This guide can help you.

I recommend reading the PDF specification so you will know what to look for.
The links are stored in the Annotations object so you will need some software to parse those.
I am trying to read a PDF on iPhone, I got to know that we can get the info about PDF from CGPDFDocumentGetCatalog method. But, this method returns a CGPDFDictionaryRef. I have browsed through the documentation and didn't find any method to extract its Key/Values. Please help me if anybody has solution for the problem. Or you can tell if we can have any other way to extract data from PDFs.
It seems that you have to extract the names of the values first. Take a look to this site especially the allScriptsInPDFDocument method
I have just checked out the documentation and it has a load of functions for getting key value pairs. If you don't know what the keys are you can use CGPDFDictionaryApplyFunction to with an appropriate callback.
Alternatively, check out the PDF Specification for a detailed description of the catalog (section 7.7.2).
