Could you tell me if I can use your products for generating PDFs from my Cocoa application, written on Objective-C for Mac OS X?
A:
Yes, you can use PDFNet for Mac OS X to read/write and edit PDF in Objective-C.
Exactly the same API is also available on iOS.
All sample code (http://www.pdftron.com/pdfnet/samplecode.html) that comes with PDFNet includes Objective-C version.
