Reading text and images from a pdf in iOS

I am showing a locally saved pdf in my iPad application. Here is the code:

NSString *path = [[NSBundle mainBundle] pathForResource:@"About Downloads" ofType:@"pdf"]; NSURL *targetURL = [NSURL fileURLWithPath:path]; NSURLRequest *request = [NSURLRequest requestWithURL:targetURL]; [pdfWebView loadRequest:request];

Now, by default, you cannot copy text or images from a PDF file that is displayed in UIWebView. Is there a way to allow users to copy text and / or images from PDF?

I am not familiar with CATitledLayer, so I'm just wondering if this can help in this case?

There is no simple answer to this question. PDFs are nested dictionaries consisting of more dictionaries and arrays. You will have to dig into CGPDFDocument . Voyeur is a great tool to use while copying to PDF files. Reader is a good starting point for rendering PDF files.

To get the text in a PDF, I use PDF Kitten (https://github.com/KurtCode/PDFKitten). It works quite well, but, as the author notes, is incomplete and does not support all types of fonts.
