ipad - Reading text and images from a pdf document in iOS

Question

I'm displaying locally stored pdf in my iPad application. Here's 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 can't copy text or images from the PDF which is rendered by the UIWebView. Is there a way to let users copy text and/or images out of pdf?

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

There's no simple answer to this. PDF's are nested dictionaries composed of more dictionaries & arrays. You'll have to dig into CGPDFDocument. Voyeur is an excellent tool to use while digging around in PDF's. Reader is a good suggested starting point for rendering PDF's.
