PDF Parsing in iPhone

Hello friend,

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.

Hi,

It seems that you have to extract the names of the values first. Take a look to this site especially the allScriptsInPDFDocument method

Thanks for your help, but, the libraries and code used their were for MAC OS and are currently unavailable in iPhone OS.

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).
